I am an Assistant Professor in the Department of Computer Science at New Jersey Institute of Technology (NJIT). Before joining NJIT in 2019, I obtained a Ph.D. in Operations Research at Iowa State University in Aug., 2012 and a second Ph.D. in Computer Science at the University of Maryland, College Park in May, 2019. 

Research Interests

Overall, my research interests broadly span the intersection of Algorithms, Operations Research, and Artificial Intelligence. I am particularly interested in randomized algorithm design and analysis for various stochastic optimization problems arising from both classical theoretical models, such as Online Matching, Secretary Problem, Prophet Inequality, and Multi-Armed Bandits, and practical applications in fields like E-commerce, Internet advertising, crowdsourcing markets, data mining, databases, and revenue management. My expertise lies at the intersection of Randomized Algorithms, Probabilistic Models, Stochastic Optimization, and Applied AI. My recent research primarily focuses on following directions: 

• Variance Analysis of Online Algorithms. 

• Algorithm Design and Analysis for Online Submodular and Coverage Maximization. 

• Promoting Fairness and Equity in Online Resource Allocation.
