Great Time at the Amazon Supply Chain Optimization Summit in Seattle

This past Sunday and Monday I had the pleasure, with 33 other invited faculty from around the globe, to take part in the 1st Amazon Supply Chain Optimization Summit in Seattle. There were 4 female faculty that took part. Universities represented included, among others: MIT, Stanford, CMU, Georgia Tech, UC Berkeley, UPenn, Cornell, Columbia, U. of Washington, U. of Colorado, U. of Florida, and several universities in Canada, Italy, and Brazil, and., of course, UMass Amherst!

The hospitality extended to us was outstanding with lodging at the Inn at WAC (Washington Athletic Club) in downtown Seattle, a tour of a fulfillment center about an hour outside of downtown., complete with the largest robotic arm in the US and Kiva robots, dinner at the Museum of Natural History in Seattle, and a full day of talks and discussions with lunch and snacks provided!

I was most impressed by the Amazon staff and researchers that we met, known as "Amazonians." Would you believe that Amazon has about 300 PhDs in Operations Research working for the company, 50 PhDs in economics, 50 on machine learning, to start!

I was also very impressed by the push into sustainability started about 1 year ago and the drive to be customer-focused and to provide products the quickest AND the cheapest.  I spoke with PhDs in Computer Science, Math, OR, and even Material Science, who is focusing on packaging optimization. The push to innovate and use the latest in technology, models, and algorithms was very inspiring.

Below are a few photos from Seattle - we were lodged very close to Pike's Market so Sunday morning after lots of flying the day before I could get some nie long walks in before our tour of the fulfillment center.

 Immediately above in the photo are my great colleagues, Dr. Mauricio Resende of Amazon,  Dr. Oleg Prokopyev of the University of Pittsburgh, and Dr. Sergiy Butenko, all great optimizers, at the Museum of Natural History event in Seattle. Dr. Resende joined Amazon about 10 months ago from AT&T.

Below I am standing with Dr. Greg Duncan, the Chief Economist at Amazon, who was one of our speakers, and who had worked with my good INFORMS colleagues before at GTE and Verizon - Dr. Les Servi and Roger Tobin. His PhD committee at UC Berkeley included Dan McFadden and George Akerlof, both Nobel laureates in Economic Sciences.
 Many thanks to Amazon for such a stimulating Supply Chain Optimization Summit. I am sure that there will continue to be opportunities for collaboration.

And after landing yesterday in Bradley Airport I was greeted by a rainbow - simply perfect!

A Science PhD is Not a Waste of Time -- A Doctorate Lasts a Lifetime

You may have seen some of the articles on recipients of science PhDs who may not be gainfully employed, which, may simply mean that they could not get a tenure-track job in academia.

You may even have read or heard that "Getting a PhD in science is a waste of time" because of the years involved in taking courses, doing the research, and writing and defending the dissertation, at a salary or stipend that does not compare to a well-paying job.

Reading such articles, including a recent one in The Washington Post, frankly, I felt as though there was some sort of anti-science conspiracy in the US, when, ironically, so many students from abroad are flocking to US institutions of higher education for degrees in science, engineering, and related professions.

At the same time, various scientific organizations, as well as companies, are arguing for enhanced education and more students in STEM (Science, Technology, Engineering, and Mathematics) fields,with a recent OpEd piece in The New York Times, by Thomas L. Friedman, "I Made the Robot Do it," discussing how a soon to be released programmable robot and associated technology may not only help to create good jobs but also eliminate bad ones.

Friedman begins his OpEd with an infamous quote by a congressman and member of the House Science Committee, which makes Friedman wonder some days how the US became thr richest, most powerful country, and, more important, how we are going to stay there.  He thanks God that there are still innovators and entrepreneurs who are not interested in politics but who go out and invent stuff and fix stuff and collaborate on stuff. Sounds to me exactly what a science PhD is about.

Friedman attended a design workshop at Rethink Robotics near Logan Airport in Boston and the company's founder, Richard Brooks, who has a PhD, is also behind the Roomba vacuum cleaner. A few days ago, while dropping off my daughter at college, I met one of the Board of Directors of this company, whose daughter is my daughter's dorm-mate, and I had one of the most intellectually stimulating conversations on technology, cloud computing, and ideas for the future with him.

Now, there is another voice of reason.

Daniel Lametti, an advanced  doctoral student, in an article in Slate,  "Is a Science Ph.D. a Waste of Tine?" writes that: focusing on the hypothetical financial loss ignores why many graduate students pursue a Ph.D. in the first place: intellectual curiosity. The biggest perk of graduate school in science is getting paid to learn. Many of the people I spoke to missed the intellectual and logistical freedom of graduate school--being able to set their own hours and pursue a wide range of academic activities. Nobody expressed regret about working towards a science Ph.D.; graduate school, most said, was a lot of fun. I'd have to agree.

In addition, Lametti notes that: the product of a doctoral education has been a dissertation--a body of research that, in a small way, moves a field forward. There's nothing wrong with contributing to science and then moving on. The work won't disappear. 

And my favorite line from Lametti: Dissertations are published and doctorates last a lifetime.

In the article, he also highlighted cases of how methodologies learned while a doctoral student, such as statistics and computer programming (although I hope that some of these tools would have been learned as an undergraduate student), can be applied in many different sectors. We all have friends who have left academia to go into the private sector, including Wall Street, precisely because of such marketable skills.

In such fields as operations research and management science, the latter is the track that my doctoral students concentrate in at the Isenberg School of Management at UMass Amherst, there are numerous opportunities in academia and industry after getting the PhD and some even move between the two. Of course, statistics, computer programming, plus modeling and optimization and algorithms, are essential tools for scientific research in operations research / management science.

In honor of science, technology, invention, and getting a PhD, below I have posted a photo of my Roomba, which I had mentioned in an earlier post, was a present given to me by a doctoral student, whose dissertation I had chaired. He is now a professor educating others.
