Biography

I completed my Bachelor's degree in Statistics from Presidency University, Kolkata in 2017. Next, I completed my Master’s degree in Statistics from Indian Institute of Technology, Kanpur, in 2019. Later, in the same year, I joined ISI as a research scholar, where I was working on some problems related to High-dimensional inference involving sparsity. In 2025, I joined Dhirubhai Ambani Institute of Information and Communication Technology, Gandhinagar as an Assistant Professor.

Specialization

High-dimensional Inference, Multiple Testing, Posterior Concentration, Variable Selection, Sparse Signal Recovery
