About Me

I am an NSF postdoctoral fellow in the Department of Statistics at the University of Warwick. My sponsoring mentor is Prof. Gareth Roberts. I am currently studying computational complexity for Markov chain Monte Carlo samplers used in high-dimensional Bayesian models. I am also interested in methods for intractable likelihood problems.

Before joining Warwick, I graduated with a PhD from the School of Statistics at the University of Minnesota working with Prof. Galin Jones. My thesis was on output analysis for Markov chain Monte Carlo. Before Minnesota, I obtained my Masters from Rutgers University and completed my undergrad from Lady Shri Ram College for Women, New Delhi, India.

For 2017-2018, I am co-organizing the Algorithms & Computaionally Intensive Inference seminar series with Murray Pollock.
