At a recent seminar talk, I was amazed to note that one of the two coauthors (not the presenter) was the president of a large and well-known university, since I had always assumed that taking on such a position would necessarily mean the end of a research career.
Are there m/any examples of people that continue to do substantial amounts of research when in a senior administrative position, such as dean, provost, president, etc.?
Do research faculty often become deans, presidents, etc.? Why do faculty usually do this? (I understand that there might be a pay increase, but does it usually indicate that they no longer want to do research as intensely?)
