Charles L. Epstein is a Thomas A. Scott Professor of Mathematics at the University of Pennsylvania, Philadelphia.[1]

Research interests[edit]

Epstein is an analyst and applied mathematician. His interests include microlocal analysis and index theory; boundary value problems; nuclear magnetic resonance and medical imaging; and mathematical biology.

Education and work[edit]

Charles Epstein was an undergraduate in mathematics at MIT and graduate student at the Courant Institute, NYU, where he received his PhD in 1983 under the direction of Peter Lax.[2]

He did a postdoc with William Thurston before moving to the University of Pennsylvania, where he has been since. Epstein won a Sloan Research Fellowship in 1988.[1]

He is currently Thomas A. Scott Professor of Mathematics and graduate chair of Applied Mathematics and Computational Science.

Awards and honors[edit]

In 2014, he became a Fellow of the American Mathematical Society "for contributions to analysis, geometry, and applied mathematics including medical imaging, as well as for service to the profession".[3]
