About me:
PhD degree in math granted by UC Berkeley in May 2014. Research interest: Diophantine Geometry and Algebraic Dynamics. Co-advisors: Professors Thomas Scanlon and Paul Vojta (and, unofficially, Professor Thomas Tucker at the University of Rochester).


From 7/2014-6/2017: I will hold the position of a UBC-PIMS Distinguished Postdoctoral Fellow appointed jointly by the mathematics department of the University of British Columbia and the Pacific Institute for the Mathematical Sciences mentored by Professor Dragos Ghioca. My CV is available upon request.
