The George Washington University

 

I joined the Department of Biostatistics and Bioinformatics at the George Washington University as an assistant professor in the Fall of 2023. I completed my Ph.D. from the Department of Statistics at the University of Michigan, Ann Arbor. I worked as a post-doctoral researcher at the Department of Mathematics at Ruhr Universitat Bochum, Germany, for three years. I am interested in developing statistical methodology for analyzing longitudinal, spatial, and time series data focusing on high dimensional and functional observations. Please visit my research page for more details about my research and publications.

I am always looking for new and interesting opportunities for collaboration. Please get in touch with me if you are interested in collaborating on a research project.

Research

My primary research interest is modelling and analyzing dependent data. Dependence among observed data is a phenomenon that arises naturally in important problems, especially in time series and spatial data. I am specifically interested in large complex objects, e.g. functional time series data or spatial surface data, which has emerged as an important object of interest in statistics with the availability of high-dimensional and high-resolution data in recent years. A detailed description of my research is available here. Some of my current interests are:

  • Functional Data

  • Time Series Data

  • Spatial Statistics

  • Shape Constrained Inference

  • Asymptotic Theory

  • Empirical Processes

  • Long Range Dependence

  • Non-parametric Inference
