Professor of Mathematics, ETH Zürich.
Senior Chair, Swiss Finance Institute.
Currently, I am a professor of mathematics at the Swiss Federal Institute of Technology
in Zurich (Eidgenössische Technische Hochschule Zürich)
and the Chair of the Department of Mathematics.
I teach and research
on nonlinear analysis in partial differential equations, stochastic processes and
I also hold a Senior Chair at the
Swiss Finance Institute.
My current research is concentrated on mathematical finance and together with Professors Larsson,
Schweizer and Teichmann, we form the
Stochastic Finance Group
at ETH Zurich.
Prior to moving to Zurich, I spent nine years in Istanbul, Turkey and nineteen years
in the United States of America. During my tenure in Turkey, I held the Isik Inselbag Chair at
Sabanci University for two years and was a member of the Mathematics Department at Koc University
for seven years prior to that. I also served as the Dean of the College of Administrative Sciences
and Economics of Koc University between February 2002 and September 2007.
I received my Ph.D. from the Division of Applied Mathematics of Brown University.
After a one-year postdoctoral stay at the Institute for Applied Mathematics, I joined
the Department of Mathematical Sciences at Carnegie Mellon in 1986. In September 1998,
I moved to Princeton and became the Paul M. Wyhtes '55 Professor of Engineering and Finance.
At Princeton I was affiliated with the Program in Applied and Computational Mathematics,
the Department of Operations Research and Financial Engineering (ORFE) and the Bendheim Center of Finance.
I have co-authored a book, with Wendell Fleming, on viscosity solutions and stochastic control;
Controlled Markov Processes and Viscosity Solutions, Springer-Verlag, 1993 (second edition in 2005),
and authored or co-authored several articles on nonlinear partial differential equations, viscosity solutions,
stochastic optimal control and mathematical finance.
The meeting METE 2018
provides an overview and the scope of
my research interest and contributions.
Currently, I am an associate editor for SIAM Journal of Financial Mathematics (SIFIN),
Interfaces and Free Boundaries, Mathematics and Financial Economics (MAFE)
and the ESAIM Journal of Control, Optimization and Calculus of Variations (COCV).
In 2008, I was awarded a European Research Council Advanced Project
titled Mathematical Methods for Financial Risk Management.
During 2011-2016, I have been the Executive Secretary of the
Bachelier Finance Society.
In 2014, I received an
Alexander von Humbolt Foundation Research Award. In 2015, I was elected as a SIAM Fellow.
