GroetschCHUCK GROETSCH—a native New Orleanian—is Professor of Mathematics at the University of Cincinnati. Mieczyslaw Altman supervised his Ph.D. at LSU (1971), where he also studied with Pasquale Porcelli. His research centers on the theory of approximation methods for ill-posed inverse problems and he has a fairly serious amateur interest in the history of science. He serves on the editorial boards of several journals and is the author of several books, the latest of which, Inverse Problems in the Mathematical Sciences, was recently published in a Japanese edition. Groetsch is a recipient of the MAA's George Polya Award and a recovering department ex-head. Sandy is his wife, not his niece.
