RESEARCH INTERESTS

My reasearch interests are

1. Statistical inference: frequentist and Bayesian methods, Pretest and Shrinkage strategies, generalized confidence interval and generalized p-value.

2. Inference in stochastics processes: estimation in diffusion processes, Estimation and testing in regime-switching Markov processes.

3. Applied probability and Asymptotic theory in statistics: asymptotic properties of estimators and large-sample inference.
