Short Bio
Thaleia Zariphopoulou is the holder of the Presidential Chair of Mathematics and the V.F. Neuhaus Professorship of Finance at the University of Texas at Austin. Previously, she was the Laun Professor at the University of Wisconsin, Madison and from 20092012, the first holder of the OxfordMan Chair in Quantitative Finance at the University of Oxford.
Her area of expertise is Financial Mathematics and Stochastic Optimization. She has published extensively in the areas of investments and valuation in incomplete markets, and introduced novel approaches to indifference valuation and dynamic risk preferences.
She has served very actively the community of Financial Mathematics. She sits on the editorial board of eleven academic journals and monograph series, and she is the Editor of the SIAM Series in Financial Mathematics. She has served in various prize committees and panels. She has also been the ViceChair (20072010) of the SIAG Activity Group in Financial Mathematics and Engineering, and has served as VicePresident (20042006) and President (20062008) of the Bachelier Finance Society.
In 2012, she was elected SIAM Fellow and in 2014, she was an invited speaker at the International Congress of Mathematicians in Seoul.
