Our People

There are as many research interests at Regenstrief as there are investigators. Our faculty researchers, affiliated primarily with the Indiana University, Indiana University-Purdue University Indianapolis, and Purdue University, come together from across a multitude of disciplines. Yet we are united by a passion to discover and implement ways to deliver the highest quality healthcare possible to all people.
