Distinguished Professor Victor Isakov of the Department of Mathematics, Statistics, and Physics passed away Friday, May 14, 2021 at the age of 73 after a battle with cancer. In 1988, Professor Isakov joined Wichita State University as a Professor of Mathematics specializing in Partial Differential Equations and Inverse Problems. In 2000, he went on to become the Emylou Keith and Betty Dutcher Faculty of Distinction Endowed Professor due to his outstanding contributions to research in the area of inverse problems. Professor Isakov was recognized as a world-class authority in inverse problems, and he produced many original and breakthrough results for linear and nonlinear inverse boundary value problems. He authored 140 papers in mathematical journals and three books in the subjects of inverse problems and mathematical physics. He also organized several conferences around the world and advised many graduate students. His research has continuously been supported by NSF since 1990. His passing is a huge loss to both the Wichita State University and the inverse problem community.
