Effective September 1, Mark Gockenbach is the new department chair. He joins UD from Michigan Technological University, where he served on the faculty for 22 years.
Gockenbach received his PhD in Computational and Applied Mathematics from Rice University in 1994, and held faculty positions at Indiana University, the University of Michigan, and Rice University prior to joining the Department of Mathematical Sciences at Michigan Tech as an Assistant Professor in 1998. In 2001, he was promoted to Associate Professor and became the Director of Graduate Studies. He was then promoted to Professor and also became department chair in 2006, a position he held until leaving Michigan Tech to come to UD.
A numerical analyst, Gockenbach's research has been in software for large-scale optimization problems, inverse problems in elasticity, and regularization theory for inverse problems. His most recent work focuses on the singular value expansion and generalized singular value expansion. He supervised seven PhD students at Michigan Tech and has written books on partial differential equations, finite element methods, linear algebra, and linear inverse problems. He served as a Visiting Lecturer for the International Mathematical Union and is on the Advisory Board of the NSF-funded project Progress through Calculus.
