Security and Emergency Management in a Major Hospital

Today, we had the great pleasure of hosting Mr. Thomas, Lynch, the Director of Security and Emergency Management at Baystate Health in Springfield, Massachusetts. This is a big level 1 trauma hospital, which, on some days, as happened last week with 397 patients, is the busiest hospital in terms of emergency room visits in Massachusetts. He has been the Director of Security at Baystate Health since 1995 and the Chair of the Emergency Management Committee for the Baystate Medical Center since 1997.  Prior to his arrival at Baystate, he served for 11 years as the Assistant Director of Security at Mt Sinai Medical Center in Manhattan and also served for 10 years as an officer in the Army Military Police Corps.

The title of Mr. Lynch's  presentation to my Humanitarian Logistics and Healthcare class was: Healthcare Emergency Management. 

Mr. Lynch emphasized the very dynamic, integrated process that is used in the hospital setting with an all hazards approach to emergency management. The challenges in such a setting are immense and his team, the hospital staff, and, of course, the medical professionals are constantly drilling and continuously improving their processes. He noted the importance of table top exercises and real drills.

He shared with us the following scenario: how an evacuation was handled from an Operating Room during surgery because there was smoke. Practicing fire drills had helped and the patient that was being operated on was moved safely to another room and the surgery completed. Think of the associated issues of sterility, for example.  

Mr. Lynch shared with us his wealth of experiences including the handling of VIP patients while he worked at Mt. Sinai Hospital in Manhattan. The VIPs, patients at separate times, included  a close relative of the Saudi king and a renowned Orthodox rabbi, whose supporters created surges. It was interesting to see, given that it was July, that there were men in raincoats around the hospital for the former (clearly with armaments beneath).

He emphasized all phases of disaster management, which we have been covering in class, and especially risk mitigation and the lessening of exposure to risk, with preparation and planning so that you can adequately respond. He said that more efforts should be spent on recovery. He noted how hospitals are accredited and the accrediting body shows up unannounced every three years (a bit different from the forthcoming AACSB team visit for the accreditation of our business school later this month). He also noted that Baystate Health in Springfield is one of three designated Ebola treatment units in Massachusetts and that unit is now complete after 1 1/2 years of planning and work.

Federal law requires that patients are treated according to the EMT law and the medical center has to prepare for surges of patients, as well. Sometimes, police assist in stopping influxes at the perimeter because there are only so many patients that can be handled. He spoke of surges, post 9/11, due to fears about anthrax.  At times, when there are casualties family members and friends can also cause congestion in the emergency rooms.

He emphasized "serving the most people that you can save" when it comes to a hospital evacuation and, ideally, one hopes just for a horizontal evacuation - to another part of the building, for example, rather than a vertical one (down stars). He mentioned a flood in Houston a few years back during which it took 8 staff members to carry patients down 6 flights of stairs.  We've learned from Superstorm Sandy that generators should not be in basements, which can flood.

He emphasized 3 things that are very important to remember and respond to in the order below:

1. Take care of yourself (this is hard sometimes for medical professionals who are always trying to save lives),

2. Take care of other people, and only then

3. Take care of property.

One has to manage the disaster and keep the hospital running, too. By federal law, a hospital is required to be self-sufficient, post a disaster, for 96 hours.

Mr. Lynch also noted the criticality of Medicare and Medicaid for the financial survival of a hospital and that immediately after an incident, the team gets together and identifies what can be done better. The focus on continuous improvement, I am sure, resonated with the Operations and Information Management and Industrial Engineering students in the class. He noted that similar incidents continue to happen so one must learn and improve and that could include getting a badge maker on site so that you can identify people promptly.

He also told the class that relationships matter with your partners and it makes matters so much easier and more seamless if you have good working relationships with the police and fire departments, the Department of Public Health, and also Homeland Security. He also emphasized that the Public Affairs department is crucial in dealing with the media since a hospital's reputation is very important.

The incidents that one worries about are so different from issues in the commercial space: mass casualties, which the hospital deals with on a regular basis, infant abductions, and, of course, surges, cases of violence, etc. I was also impressed that the incident commander can change from incident to incident depending on the situation and even time of day. The Chief Operation Officer, who is a female, would be in charge of many emergencies but the VP of Facilities would be in charge of those having to do with his responsibilities. At night, an administrator would be on call.

Mr. Lynch's presentation was very informative and fascinating and I am so grateful that such a professional would take tie out of his very busy schedule to share his experiences with my students. Having such guest speakers is invaluable for education.

His lecture can be downloaded here.

Hosting Great Speakers at the Isenberg School This Semester!

The Spring semester is off to a great start.

One of the highlights, I find, of each semester, is the speakers that we bring to campus, which enhance the education of our students and even the faculty. Also, the provide novel networking opportunities.

Sometimes the logistics of scheduling speakers can be challenging since the one inviting should also be present. This semester I have made commitments to speak at Yale University, the Mitre Corporation, the University of Buffalo, and Carnegie Mellon University.  I am also hosting speakers through our UMass Amherst INFORMS Speaker Series plus speakers in my course on Humanitarian Logistics and Healthcare class.

Through the UMass Amherst INFORMS Speaker Series, we have three, already confirmed, great speakers: Dr. Renee Pratt of the Isenberg School, Dr. Michael Johnson of UMass Boston, and Dr. Les Servi of MITRE. The students of the award-winning UMass Amherst INFORMS Student Chapter, which I have been the Faculty Advisor of for 12 years, help out with the logistics and the advertising of these talks. They prepared the nice posters below.
Dr. Michael Johnson will be speaking on March 4, 2016, and his topic will be Community-Based Operations Research. Once we receive all the information on his presentation, we will disseminate. Dr. Johnson is behind the terrific INFORMS initiative: Pro Bono Analytics.

With topics this semester such as Information Technology and Healthcare, Community-Based Operations Research, and Cybersecurity, I am sure that the talks and  the discussions with the audience will be very stimulating and engaging!

In addition, this semester, I am hosting the following speakers in my Humanitarian Logistics and Healthcare class:

Mr. Jeff Hescock, who is the Director of Emergency Management and Business Continuity at UMass Amherst, and who was the first guest speaker in my class this semester;

Mr. Thomas Lynch - Director of Security - Baystate Medical Center Springfield;

Mr. Brad Campbell, 1st Vice Chair, American Red Cross of Western Massachusetts, Executive Director, Home Builders & Remodelers Association of Western MA;

Mr. Rasmus Dahlberg, 
Copenhagen Center for Disaster Research, Department of Public Health, University of Copenhagen, Denmark;  (I also hope that Mr. Dahlberg will give a UMass Amherst INFORMS presentation);

Lt Col James G. Bishop, Lt Chief, Public Affairs, Westover Air Reserve Base. We will also have Skyping in  Mr. Ken Hundemer, Director of Operations for the Denton Amendment Humanitarian Assistance Program, located at Charleston Air Force Base, SC.

The above speakers are part of our Professor for a Day initiative at the Isenberg School.

Looking forward to all of our guest speakers!

Renowned Economist Professor Sam Bowles on Economic Inequality

After teaching two classes today, I had the pleasure of attending Professor Samuel Bowles' lecture on "The Origins and Future of Economic Inequality." Appropriately, Sam Bowles was giving the inaugural Samuel Bowles lecture. He is a renowned economist and is a UMass Amherst Professor Emeritus. He is now heading the behavioral sciences program of the Santa Fe Institute. After 40 years at UMass Amherst he also had an affiliation with the University of Siena in Italy.

I figured that the lecture would be standing room only so I got there early and it was wonderful to even see Bowles' long-time collaborator, and also a former UMass Amherst Professor, Herb Gintis. I have had the pleasure of seeing Herb at a workshop in Hawaii, at which we were both invited speakers (and all our expenses were paid) and also at a conference at the University of Maryland. And, as I mentioned to him today, when I arrived in Gothenburg, Sweden in my apartment there as a Visiting Professor last Spring, I turned on the television and there was Herb being interviewed! No wonder I always feel so at home in Sweden!

I could not resist taking a photo of Herb Gintis featured above.

Professor Bowles was introduced by Professor Michael Ash of the UMass Amherst Economics Department. We had hosted Professor Bowles back in 2009 in our UMass Amherst INFORMS Speaker Series. He was mesmerizing then and today as well.
Bowles spoke about his data-driven research to identify why there is economic inequality and his research tackles problems over centuries. He noted how, as a student in a school in New Delhi, India, he struggled with trying to understand why people were so similar and yet some suffered from poverty. After being denied tenure at Harvard he decided that he "would either leave economics or change economics" and he has been doing the latter ever since. Luckily, we had him at UMass Amherst for 40 years. Harvard's loss was our  and the world's gain!

He is fascinated (and who is not) by such questions as why inequality may persist and intensify and on what does a more egalitarian future depend.

He described mobile hunter gatherers for whom cooperation was an essential part of their livelihood and brought out the kudu (featured below).
Since there were no refrigerators and kudu meat is perishable the society would divide up the parts of the kudu and would share.  It would be wasteful not to share. Land ownership, which is associated with hierarchical structures, rather than egalitarian ones, changed societies and wealth holdings. Inequality took place because of the rise in wealth that could be stored and inherited. Hence, farming also played a role in economic inequality.

Fascinatingly, Bowles noted that the wealth of hunters gatherers was knowledge and networks! Public speaking was important because you had to convince others. Some would walk for miles to interact with others as an "insurance network," a phrase that resonated with me.

The inheritance of material wealth was becoming much greater than the inheritance of human capacity and hunters gatherers took many years to acquire their skills and knowledge.

He spoke of the Gini coefficient with a value of 0 signifying perfect equality and a value of 1 corresponding to ownership of 1. He also presented graphs of Gini coefficients for different countries and, of course, some of my favorite ones - the Nordic countries - were singled out as having low Gini coefficients, so this shows a redistribution of wealth. He also showed  Lorenz curves for measuring inequality.

He emphasized that knowledge and human capacity now are more important than material wealth. We are past the industrial society and in the knowledge and information-based economy.. How important is material wealth in producing what we need?

He presented a math model from a published paper with 4 terms and noted that the cost of redistributing in a society of knowledge, networks, and human capacity may be lower.

Of course, he mentioned Thomas Piketty's book, "Capital in the Twenty-First Century."  Piketty delivered the Gamble lecture last year at UMass and I blogged about it. Bowles said that he was interested in Human Capital.

In the information-based economy, he said that "the winner takes all." No longer is it just the local singer that you may care about but the best singer and songs and the same for apps. He said something quite controversial - that intellectual property should be abolished. He also mentioned that because of the World Wide Web we have a "weightless economy," which I found quite interesting.

He also stated that the US because of its great inequality has a huge amount of  "guard labor," which is a drain on the economy.

I very much appreciated hearing him talk about knowledge, creativity, and networks and educational institutions, such as, of course, the university at which I teach.

The Q&A session that followed was great with issues of politics and poverty highlighted.

It was definitely a day of intellectual rigor and delights and, interestingly, the material that I covered in my afternoon seminar was an introduction to variational inequalities - a mathematical formulation that contains optimization problems as special cases. So, inequality was definitely the dominant theme for today.

Bowles in his summary and conclusions also noted that the politics of redistribution of wealth is extremely important.

Emergency Management at a University

A university is an ecosystem with many interacting parts.

The resiliency of a university depends on the procedures and practices in place for emergency management.

Today, we had the pleasure of hearing Mr. Jeff Hescock, the Director of Emergency Management and Business Continuity at UMass Amherst, in my Humanitarian Logistics and Healthcare class at the Isenberg School. He was a terrific Professor for a Day!
Mr. Hescock's described how his group, with many partners at UMass, prepares for a variety of emergencies, both man-made and natural ones, and assesses a page of risks that can affect students, research, energy, and infrastructure, to start. He also spoke of the emergency alert system, which includes text and email alerts, as well as sirens, and postings on the UMass homepage. The importance of relaying timely information was emphasized as well as post incident discussions and evaluations.

The National Weather Service recently awarded UMass Amherst a Storm Ready designation, the first public university in Massachusetts to receive this designation.

I also very much enjoyed his discussion of mitigation in terms of identifying flood plain regions and potential power outages. Luckily, we have our own power plant on campus but it can only generate about 60% of the university's needs. hence, there are generators in place at crucial locations.

UMass Amherst also works closely with the ton of Amherst in emergencies especially in terms of planned events (the Super Bowl, concerts at the Mullins Center, for example). Also, there are strong relationships with the other colleges in our 5 college system.

A major part of his presentation covered the response to the Boston Marathon bombing that took place at UMass Dartmouth, when he worked at the UMass President's office, because one of the perpetrators was a student there. This event emphasized vividly the importance of having best practices in place, including evacuation and sheltering. Many of the students, who could not go home, once UMass Dartmouth was evacuated, were sheltered at a local high school.

How a university responds to an emergency and deals with the news media can also have far-reaching impacts on its reputation.

UMass Amherst regularly runs different emergency exercises, including a sheltering exercise a few years ago that several of my students and I observed. This year, in April, it will be building a healthcare crisis exercise, inspired by outbreaks of meningitis at various campuses last year (at Princeton and the University of Oregon, for example).

Mr. Hescock's presentation can be downloaded here.

Clearly, the importance of information sharing, collaboration, and  great teamwork were highlighted. And, of course, when it comes to business continuity, one can't underestimate the importance of information technology as well as shelter and food for students!

Many thanks to Mr. Hescock for such an illuminating and educational guest lecture today.

Students benefit greatly from ghearing from practitioners.

The Most Impactful Papers in Transportation Science in 50 Years - A Walk Down Memory Lane

I was absolutely delighted when INFORMS sent out an announcement last Friday that it was making available for free download the 12 Most Impactful papers published in the journal Transportation Science in its 50 year history. These papers are listed below in chronological order.

According to the Transportation Science website: The selection was guided by the following principles. Even though overview and survey articles are important, valuable, and often highly cited, they were excluded. Highly cited papers (either in terms of total number of citations or in terms of number of annual citations) were prime candidates. However, the impact of an article is not always captured by the number of citations, so a few articles have been included because several editorial board members felt they needed to be. In the end, the articles represent most, but not all, the research areas that have contributed and continue to contribute to the success of the journal.

Seeing the list of papers brought back so many memories and the list includes such major themes in transportation as traffic assignment and network equilibrium, location theory, network design, and vehicle routing, plus even pedestrian crowd dynamics. Below, I reflect on the impact of the papers as well as the authors I have met and some I have come to know very well.

The first paper is: An Algorithm for the Traffic Assignment Problem, S Nguyen; Transportation Science 8 (3), 203-216, 1974. I met Sang Nguyen at the first conference I ever attended as a doctoral student at the University of Montreal. This paper, and those that followed, addressed algorithms for one of my favorite problems in transportation! The model formulated and solved was one in which you could reformulate the traffic assignment problem as a convex optimization problem.
The second paper,  On Stochastic Models of Traffic Assignment, CF Daganzo, Y Sheffi, Transportation Science 11 (3), 253-274, 1977, is another great classic.  Carlos Daganzo was the recipient of the 2013 Robert Herman Lifetime Achievement Award in Transportation Science. He was also elected into the National Academy of Engineering. He has supervised numerous doctoral students, many of whom are good friends of mine. Incorporating stochastic elements into traffic assignment was a big innovation. Yossi Sheffi I have known for many years and I had an office down from him when I was at MIT in the Center for Transportation under the Visiting Professorship for Women program. I am also a big fan of his books, including The Resilient Enterprise. The last time that I saw Yossi was in Zurich, Switzerland, when he and I were both invited speakers at the ETH Risk Workshop on Vulnerability and Resiliency of Supply Chains in September 2013.

Carlos Daganzo also has another paper on the list of classics, paper number 6: The Distance Traveled to Visit N Points with a Maximum of C Stops per Vehicle: An Analytic Model and an Application, CF Daganzo , Transportation Science 18 (4), 331-350, 1984

The third paper on this list of classics is especially near and dear to me since it is by my PhD dissertation advisor at Brown University, Stella Dafermos:  Traffic Equilibrium and Variational Inequalities, S Dafermos, Transportation Science 14 (1), 42-54, 1980. Here you can see who has cited this great paper. Seeing the list I had to reminisce since several of the papers I had co-authored with Stella and many others with my doctoral students as well as collaborators appear there.

Below, in her memory, I have posted two photos of Stella.

The first one below,  was taken when I was with Stella at a conference in her beloved Greece, back in 1987. The second photo was taken at the International Mathematical Programming Symposium, August 28-September 2, 1988, in Tokyo, Japan. I am sure that many of you recognize that we are standing with George L. Nemhauser (more on George later in this post. Sadly, Stella passed away on April 4, 1990. Her legacy lives on.
Since the above three papers were also influenced by the book, Studies in the Economics of Transportation, Beckmann, McGuire, and Winsten (1956), I had to include below a photo of myself with Beckmann (who was on my dissertation committee at Brown) on the beach in Australia, taking a break at one of my favorite workshops ever in Mallaccootta. This photo was taken in December 1992.
Daganzo is not the only one with two papers on this esteemed list. A hearty congratulations also go out to Mark Daskin. He also has two, the first being:  A Maximum Expected Covering Location Model: Formulation, Properties and Heuristic Solution, MS Daskin, Transportation Science 17 (1), 48-70, 1983 and the second paper being number 11:   A Joint Location-Inventory Model, ZJM Shen, C Coullard, MS Daskin, Transportation Science 37 (1), 40-55, 2003. Mark is renowned for his work in location theory. I have served on several committees with him and also applaud him for his support of females in OR/MS! The second co-author in the paper above is a female. Below is a photo of Mark with transportation colleagues that many of you will recognize (Marius Solomon, Gilbert Laporte, Teo Crainic, and Hani S. Mahmassani). We awarded Michael Florian the Robert Herman Lifetime Achievement Prize that year.
The next classic paper on the Transportation Science list is: Network Design and Transportation Planning: Models and Algorithms, TL Magnanti, RT Wong, Transportation Science 18 (1), 1-55, 1984. This paper as all the others on the list is fundamental and tremendously inspiring and, may I even say, useful! Tom Magnanti, another NAE member among  authors on this list, needs no introductions. Wong was his student at MIT. Tom was a great friend and mentor to Stella Dafermos and continues to be to numerous colleagues in Operations Research and Transportation Science.

The next paper was written by another co-author of mine:  A Column Generation Approach to the Urban Transit Crew Scheduling Problem, M Desrochers, F Soumis,  Transportation Science 23 (1), 1-13, 1989. When I was a Visiting Scholar at the Sloan School at MIT in 1989-1990, I had the pleasure of interacting with Magnanti, Orlin, and so many faculty who are not only outstanding but so nice! Francois Soumis was also a visitor at MIT at that time and we wrote the paper: A Stochastic Multiclass Network Equilibrium Model, which was published in Operations Research.

The next classic paper is:  The General Pickup and Delivery Problem, MWP Savelsbergh, M Sol, Transportation Science 29 (1), 17-29, 1995. Savelsbergh and I were elected INFORMS Fellows in 2014 with some other wonderful colleagues.

And, speaking of academic small world phenomenon, Savelsbergh is a co-author, with one of my former doctoral students, Dmytro Matsypra, of a paper on network design!

Paper number 9 on this list is: A Tabu Search Heuristic for the Vehicle Routing Problem with Soft Time Windows, É Taillard, P Badeau, M Gendreau, F Guertin, JY Potvin, Transportation Science 31 (2), 170-186, 1997 . As I had mentioned earlier, vehicle routing is an extremely important class of transportation problems. The third author, Michel Gendreau, I have known and enjoyed speaking to, going back to my days as an Assistant Professor. And, for his exceptional work, Michel, at our most recent INFORMS meeting in Philadelphia, was honored with the Robert Herman Lifetime Achievement Award. I took the photo below at the TSL meeting there.
And for all of you who love air transportation, paper number 10 is: Flight String Models for Aircraft Fleeting and Routing, C Barnhart, NL Boland, LW Clarke, EL Johnson, GL Nemhauser, RG Shenoi, Transportation Science 32 (3), 208-220, 1998.  What a terrific group of co-authors! Nemhauser, I have already mentioned earlier, and the first author is Cynthia Barnhart, who is now the Chancellor of MIT. She is a member of the National Academy of Engineering, as are Ellis Johnson and George. Both Cynthia and Ellis we had the pleasure of hosting at the Isenberg School through our great UMass Amherst INFORMS Speaker Series. The photo below I took of Cynthia after her talk with our wonderful students at that time back in 2005.
Below is a photo of Ellis Johnson after his presentation at the Isenberg School in 2009. My colleague, Senay Solak, was a doctoral student of his at Georgia Tech, and continues to work on airline problems.
And since Nemhauser is a co-author, below I have posted a photo from last year's INFORMS Computing Society conference at which he gave a great keynote talk.

The twelfth paper on the list is: Self-Organized Pedestrian Crowd Dynamics: Experiments, Simulations, and Design Solutions, D Helbing, L Buzna, A Johansson, T Werner,  Transportation Science 39 (1), 1-24, 2005. I know the first author of this paper, since not only was he with Sheffi and me at the ETH Zurich Risk Workshop, which he was involved in organizing, but, last March, he was one of my hosts when I gave a plenary talk in Berlin, Germany! Below is a photo of Dirk Helbing at the workshop in Berlin last March before his talk.
Congratulations to all the authors of these classic papers and thanks for the opportunity to walk down Memory Lane!

The Criticality of Transportation in Disaster Relief and Humanitarian Operations

The new semester has begun and I am delighted to again be teaching my Humanitarian Logistics and Healthcare class at the Isenberg School of Management. As I mentioned in a previous post, I am also busy co-editing a volume on Dynamics of Disasters with two great colleagues.

A theme that is resonating time and time again with me when it comes to disaster relief and humanitarian operations is that of the criticality of transportation.

The below poster I have on my office door. It was prepared courtesy of the American Mathematical Society (AMS) when I was interviewed by Michael Breen for a Mathematical Moments podcast on my earlier research on humanitarian supply chains. The podcast can be accessed here.
Transportation is essential to disaster relief and humanitarian operations, which also includes recovery in the disaster management life cycle. Transportation is used in the evacuation of people, animals, etc., in anticipation of a disaster. It is fundamental to needs assessment at the disaster sites, once the disaster strikes, to determine the extent of casualties and survivors' demand for necessary relief supplies. It is even an essential component for supply collections from donors or places of procurement. Finally, transportation in often very challenging environments to points of demand can involve multiple different modes of transportation with great time pressures, followed by last mile deliveries. And, when it comes to recovery post a disaster, the removal of debris and detritus due to the sustained damage cannot happen without transportation, as well as the followup rebuilding. the former was a huge issue post the Haiti devastating earthquake of 2010, as vividly captured in a New York Times OpEd by our Georgia Tech operations research colleagues.

Given the importance of transportation in this space there have arisen partnerships between private companies and  humanitarian organizations as well as the well-known Denton Program, for private U.S. citizens and organizations to use space available on U.S. military cargo planes to transport humanitarian goods to countries in need. I am delighted that one of the highlights of my class will include speakers from the Westover Base in Chicopee who will be discussing military logistics and the Denton Program.

My most recent study, Freight Service Provision for Disaster Relief: A Competitive Network Model with Computations, to appear in Dynamics of Disasters, I.S. Kotsireas, A. Nagurney, and P.M. Pardalos, Eds., Springer International Publishing Switzerland, focuses on freight service provision, under competition, for  disaster relief. Therein, I argue the importance of capturing nonlinearities associated with transportation in humanitarian operations to capture congestion as well as competition and even material convergence.

Looking Forward to Speaking at Yale at its Network Science Institute

The new semester begins at UMass Amherst on Tuesday. It will be a very busy semester but a thrilling one. Besides teaching two courses at the Isenberg School, I will also be hosting speakers not only in my classes but also through the UMass Amherst INFORMS Student Chapter as its Faculty Advisor. Plus, I will be traveling to give invited lectures at various universities and companies.

I very much enjoy traveling to different locations and giving talks and always come back with new ideas, an expanded professional network,  wonderful memories, and, sometimes, even adventures. Plus, what could be better than interacting with faculty, students, and practitioners that come to your presentations?

The first invited seminar that I am giving in 2016 will be at Yale University. Although I have given talks at such Ivy League schools (at some of these multiple times) as: Harvard, Brown, Cornell, and UPenn, I have never before spoken at Yale. For this reason, and quite a few others, I am quite excited about speaking there on February 17, 2016.

Since my host at Yale will be the Network Science Institute, it will be extra special to be surrounded by those who share my passion for networks!

I am speaking in the Yale Institute for Network Science (YINS) Distinguished Lecture Series and the title of my presentation is: "Supply Chain Networks Against Time: From Food to Pharma." The abstract and announcement YINS has already graciously posted.  My presentation will be videotaped. The lecture and Q&A will take place from noon until 1:30PM.

I have started working on my presentation, which I will be polishing over the next couple of weeks.
The Directors of the Institute for Network Science are Professor Nicholas A. Christakis and Professor Daniel Speilman. The Executive Director is Dr. Tom Keegan. The Faculty in Residence at the Institute represent many different disciplines from Engineering and Computer Science to Sociology, so I will do my best to have something fascinating for each of them. The Directors have done extraordinary research that has also been widely covered by the media. The YINS Distinguished Lecture Series has hosted such network science colleagues as Albert-László Barabási (whom I had dinner with on October 30,2015), Matthew O. Jackson of Stanford, and Jennifer Chayes of Microsoft Research, among others.

Also, I expect to see the INFORMS President, Professor Ed Kaplan, there, which will be an additional highlight of my visit to Yale.
