My academic interest lies in the area of operations research, more particularly in simulation and stochastic optimization methods involving Markov models. At present I am focusing on using reinforcement learning methods such as POMDP, BAMDP, Monte-Carlo Bayesian Reinforcement Learning in problems related to cybersecurity. I am also interested in multivariate statistical models e.g. Generalized Linear Models and its applications.
