About

My recent research interests center around the development and analysis of statistical methods and optimization tools for structured high-dimensional data problems, including sparse regression, low-rank, and nonparametric neural networks. The main focus is to develop robust and quantile-based methods in settings where the error distribution is heavy-tailed and/or heteroscedastic. I also work on developing and analyzing methods with nontraditional data types, such as distributed data, streaming/online data, multi-source data, and data subject to privacy concerns.
