Assistant Professor
Industrial and Systems Engineering
Rensselaer Polytechnic Institute

I am an assistant professor in the Department of Industrial and Systems Engineering at Rensselaer Polytechnic Institute (RPI). My research interests focus on computer simulation, data analytics, data-driven stochastic optimization, risk and reliability management for complex cyber-physical systems with applications, including supply chains, bio-pharmaceutical manufacturing, smart power grids with renewable energy, semiconductor manufacturing, and infrastructure maintenance. I currently serves as Associate Editor for ACM Transactions on Modeling and Computer Simulation.

I get my Ph.D. from the Department of Industrial Engineering and Management Sciences at Northwestern University. My thesis is about input modeling and uncertainty analysis in stochastic simulation. In collaboration with Professor Barry L. Nelson from Northwestern University (NU) and Professor Russell R. Barton from Pennsylvania State University, we have developed both frequentist and Bayesian approaches to quantify the impact of both input and simulation estimation uncertainty on the stochastic system performance estimation.

My two papers, ``A Bayesian Framework for Quantifying Uncertainty in Stochastic Simulation" published at Operations Research and ``Quantifying Input Uncertainty via Simulation Confidence Intervals" published at INFORMS Journal on Computing (with Barry L. Nelson and Russell R. Barton), received the 2015 outstanding publication award from the INFORMS Simulation Society.
