A political scientist named Elinor Ostrom died this morning. She was also a Nobel Prize winner in economics. Her work was the basis of my dissertation and one of the courses I taught this semester. She was also a very nice person. When she came to a conference at Princeton once, I met her at Newark airport and rode with her back to campus (at her suggestion) so that we could have thirty minutes to talk about my research plans. This was before the Nobel. Professor Ostrom’s NYTimes obituary does a nice job of explaining what was innovative about her work, as well as the challenges of doing interdisciplinary research.
