About

I am currently a Teaching Assistant Professor in the Department of Mathematical Sciences at the Stevens Institute of Technology. My research consists of developing statistical tools for analysing complex dynamic and dependent data, in particular in the context of dimension reduction for multivariate time series. For example, in the context of financial interactions, there is often some latent hierarchy present among a group of factors which leads to dynamic interaction data. I have developed methods to understand the latent structure present in data such as this.

Research

Broadly, my research consists of developing statistical tools for analysing complex dynamic and dependent data, in particular in the context of dimension reduction for multivariate time series. Technically, I conduct theoretical and applied research in Bayesian statistics, multivariate time series, factor analysis, cluster analysis, copula models, and dependencies. My current research has benefited greatly from collaborations with researchers inside and outside of statistics. Please find my research profile on Google Scholar.
