About: I am a third-year statistics PhD student at the University of Wisconsin–Madison receiving academic guidance from Professor Joshua Cape.
Research interests: I study statistically and mathematically principled methods of dimensionality reduction and structure discovery for high-dimensional and complex data. My research draws upon tools from matrix analysis, multivariate statistics, asymptotic theory, random matrix theory and numerical linear algebra.
