Faculty and Adjuncts

Albert Cohen, Ph.D.

Albert Cohen photoAlbert Cohen is the new Director of Program Development for the Actuarial Science Program. He received his Ph.D. from Carnegie Mellon University in 2007 under the supervision of David Kinderlehrer. Albert's research focuses on the interaction between probability and science and economics. This focus began with his work on a stochastic approach to the coarsening of cellular networks, and has since branched out to develop new risk measures using stochastic optimal control. This approach has also led to models of online auction behavior, stabilization of systems with white noise and the structural modeling of default bond pricing under the incorporation of recovery processes. Cohen served as the acting director and program coordinator for the Actuarial Science program until August 2013, when Emiliano A. Valdez joined the AS team as its new director. Albert is excited to work with the new Director Frederi Viens to build MSU's Actuarial Science program into a national leader in delivering
actuarial education and research.

Gábor Francsics, Ph.D.

Gábor Francsics photoGábor Francsics is an associate professor in the Department of Mathematics. He received his Ph.D. in mathematics from Rutgers University in 1992 and, prior to joining MSU, he held academic appointments at University of Pennsylvania and at Columbia University. His research interests include financial mathematics, partial differential equations, several complex variables, and analytical and geometrical questions of complex hyperbolic spaces. He has published numerous articles in leading mathematical journals. At MSU, Francsics is one of the key faculty members who helped develop and establish an AS specialization in 2003. Francsics is enjoying his role as faculty adviser of the MSU Actuarial Science Student Club.

Jacob Geyer

Jacob Geyer photoJacob Geyer is an adjunct faculty member of the Actuarial Science program. Geyer received his B.A. in mathematics from MSU, and is actively pursuing his Fellowship of the Casualty Actuarial Society (CAS). He currently works at the Accident Fund Insurance Company of America, Lansing, Mich., as Managing Director of Business Analytics and Underwriting Operations. In recognition of his significant contributions to the company, Accident Fund awarded him the Leader of the Year Award in 2013. Geyer has more than eight years of industry experience working as an actuary for Liberty Mutual, Okemos, Mich., and Accident Fund. He is on the Actuarial Science Advisory Board and is the CAS university liaison for MSU. Geyer provides guidance and supervision on some of the AS projects to meet requirements for the MTH 491B course.

Hyokyoung (Grace) Hong, Ph.D.
