The focus of my research is to expand the methodological aspects of sequential decision-making under uncertainty and its applications. In doing so, I develop novel decision rules and solution techniques to obtain policies and bounds on multistage stochastic programming and robust optimization problems. Moreover, I study such sequential decision-making problems that arise in various application areas, including telecommunications industry, healthcare sector, and supply chain management.
