## ResearchI work on various problems related to probability, mathematical finance and applications. Currently I am interested in robust portfolio theory, optimal transport as well as information geometry.

Previous courses at USC:Fall 2017: - MATH599 Topic course on Portfolio Theory, Optimal Transport and Information Geometry Spring 2017: - MATH512 Computational Finance (Financial Informatics and Simulation) - MATH118 Introduction to Statistics Fall 2016: - MATH125 Calculus I Previous courses at UW:Spring 2016: - MATH309 Linear Analysis Winter 2015: - MATH307 Ordinary differential equations Autumn 2014: - MATH308 Matrix Algebra ## ComputingR ProgrammingFor beginners I recommend The Art of R Programming by Norman Matloff. A good (intermediate-advanced) reference is Advanced R by Hadley Wickham. R Packages- RelValAnalysis. (Relative Value Analysis) Available on CRAN. Current version: 1.0 (June 26, 2014). This R package implements results in stochastic portfolio theory and the energy-entropy framework in Pal and Wong (2013). Click here for introductory slides presented in the useR! 2014 Conference. The R codes presented in the slides are collected here. |
