Affiliation and Research Interests

I am a postdoctoral researcher in the Center for Computational Sciences and Engineering (CCSE) in the Computational Research Division of the Computing Sciences Directorate at the Lawrence Berkeley National Laboratory

Broadly, my research is on Decision Making under Uncertainty. More specifically, I work on various aspects of Stochastic Programming and Distributionally Robust Optimization and their applications to groundwater management, water allocation, and energy problems. As a part of the research, I work on Feedforward Neural Networks such as multilayer perceptron and Convolutional Neural Network to generate future scenarios for future decision making. I am involved in two projects Enabling Water-Energy Decision Support Using Watershed-scale Surrogate Models (LRDR) and Institute for the Design of Advanced Energy Systems (IDAES). The latter project develops python application with pyomo (pyomo: a collection of Python software packages for formulating optimization models) 


I received my PhD in Operations Research from the Ohio State University in May 2019. My dissertation research studied stochastic optimization, particularly variance reduction for sequential sampling procedure in stochastic programming and data-driven distributionally robust optimization with applications in water resources management.
