LEXINGTON, MA (Thursday, 10/22/2015). I forgot to mention that I had lunch with David Gil, my old professor at Heller and the Chair of my Dissertation Committee. I met David in his class in 1999 as a special student at Heller and entered the Ph.D. program in 2000. It was great to see him again. He invited me to come and speak at Brookhaven the next time I was there. This is a great picture of David waving goodbye!
