RESEARCH INTERESTS:

 I am interested in general methodological research. Some of the areas that I have worked on include: Time Series Analysis, Nonparametric Bayesian Methods, High-dimensional Estimation and Inference, Estimation and Inference under Geometric Constraints, Sequential design. Currently, I am also working on Privacy and Confidentiality, particularly for time series data.
