Research interest

I am a final year Ph.D. student, working on deep generative models and Bayesian machine learning. I have particular interests in language modeling and spatio-temporal modeling. Other than this, I have broad interests in Markov Chain Monte Carlo (MCMC).

My interdisciplinary training in Machine learning, Physics and Biology encourages me to think differently. Recently, I am attempting to bring methodologies from Physics for solving sampling problems, and applying latest machine learning methodologies to unravel insights for large dataset.

I am currently looking for natural language modeling/general machine learning research scientist position.
