About me:

Research interests: Diophantine geometry, algebraic dynamics, and related problems in algebra and number theory.


7/2014-6/2017: 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.

 

5/2014: PhD in math at UC Berkeley. Co-advisors: Professors Thomas Scanlon and Paul Vojta (I was also mentored by Professor Thomas Tucker during a 3-month visit at ICERM.)

 

Teaching at UBC:
Fall 2014: MATH 200 (Multivariable Calculus)

Spring 2015: MATH 101 (Integral Calculus with Applications)
