Being in charge of the Johns Hopkins University School of Medicine is no low-pressure job; youโ€™re also chief executive officer of the whole Johns Hopkins Medicine behemoth, a $6.5 billion health system that stretches way beyond Baltimore. For the past 15 years, Edward D. Miller has held that position; as of July 1, Paul Rothman will take over.

So who is Rothman, anyway?  Well, aside from the mustache, Rothman is first and foremost a scientist.  He started out studying cell-to-cell communication in the immune system in the 1980s; he went on to apply this research to further study of allergic diseases and cancer at Columbia University. โ€œI saw young, talented people flock to his laboratory, publish and progress in their careers,โ€ said Myron Weisfeldt, a member of the search committee who was also chair of medicine at Columbia when Rothman was there. Most recently, Rothman was dean of the University of Iowa, which he hadnโ€™t expected to leave so quickly:  โ€œI really didnโ€™t know that I was a finalist until less than a month ago,โ€ Rothman told the Cedar Rapids Gazette. โ€œIt was very rapid.โ€ The family plans to maintain a home in Iowa, where they have strong ties.

The search committee seemed to like Rothman because although he has a track record as an administrator, heโ€™s quite experienced in both clinical and research medicine.  He saw patients right up until he became dean at Iowa in 2008.  But he is also โ€œan outstanding basic scientist,โ€ according to search committee member Carol Greider. One final fun fact:  he apparently has a very strong New York accent.
