Biography
Hello! I am a fifth year PhD student at the Department of Statistics at UIUC. I am fortunate to be co-advised by Dr. Sabyasachi Chatterjee and Prof. Xiaofeng Shao. I am currently working on developing asymptotic theory for total variation denoising and detecting change point in the marginal distribution of a high dimensional time series. Prior to joining UIUC, I completed my Bachelor's and Master's degree in Statistics from Indian Statistical Institute in 2021.

Nonparametric Regression; Shape-constrained estimation; Inference for dependent data, Change point detection; High dimensional probability
