I will no longer use this website. Please refer to my new webpage for updates.
I am an Assistant Professor in the Department of Electrical and Computer Engineering at Texas A&M University. My group is actively seeking self-motivated Ph.D. students and postdocs with strong mathematical backgrounds and interests in smart sustainable power and energy systems. Feel free to reach out to me if you are interested in joining my group.
Prior to joining TAMU, I was a Postdoctoral Associate affiliated with MIT Energy Initiative at Massachusetts Institute of Technology. I received my Ph.D. degree in electrical engineering from Harvard University, my master’s degree in electrical engineering and two bachelor’s degrees in engineering and economics from Tsinghua University.
My research interests lie in the intersection of control, learning, and optimization for human-cyber-physical systems, with particular applications to smart grids and smart cities. I am passionate about developing theoretical foundations and practically applicable tools that lead to intelligent, autonomous, and sustainable energy systems. In addition, I am broadly interested in data-driven decision-making, distributed optimization and control, online learning and human-in-the-loop control, model-free optimization and control, reinforcement learning, (distributionally) robust optimization, etc.
I will chair a session “Advanced Learning and Optimization for Carbon-Neutral Electricity” in the 2023 INFORMS Annual Meeting, Oct. 15-18, Phoenix, Arizona, USA. Looking forward to seeing you.
[08/2023] Check our new preprint “Towards Carbon-Free Electricity: A Comprehensive Flow-Based Framework for Power Grid Carbon Accounting and Decarbonization”. This paper establishes a comprehensive flow-based framework for carbon research and development in the electric power sector, including carbon accounting, decarbonization decision-making, and carbon-electricity market.
[08/2023] Check our new preprint “Carbon-Aware Optimal Power FLow”, which integrates carbon flow into optimal power flow to enable the optimal management of both energy and carbon emissions.
[04/2023] I won the Best Research Award (one of two, out of over 100 participants) with the Grid Edge Grand Prize of $5,000 in the Ph.D. Dissertation Challenge in IEEE PES Grid Edge Technologies Conference and Exposition 2023.
[03/2023] My Ph.D. thesis was selected as one of the four Outstanding Doctoral Dissertations (2020-2022) by IEEE Power & Energy Society (PES). I am also invited to present my thesis work in the PES outstanding doctoral dissertation panel in the 2023 IEEE PES General Meeting.
[02/2023] Check our new preprint “Continuous-Time Zeroth-Order Dynamics with Projection Maps: Model-Free Feedback Optimization with Safety Guarantees”, which introduces a class of model-free feedback methods (termed “Projected Zeroth-Order (P-ZO) dynamics”) for solving generic constrained optimization problems with projection. This is the “Part-I” paper that focuses on the problem formulation and theoretical analysis, and our “Part-II” paper on the practical applications of P-ZO methods will appear soon.
[06/26/2022] Check our new preprint “Model-Free Feedback Constrained Optimization Via Projected Primal-Dual Zeroth-Order Dynamics”, which proposes a continuous-time zeroth-order dynamics algorithm that can autonomously steer a black-box system to the optimal solution of a constrained optimization problem using only output feedback.
[05/15/2022] Our paper “Improve Single-Point Zeroth-Order Optimization Using High-Pass and Low-Pass Filters” was accepted for the 39th International Conference on Machine Learning (ICML 2022).
[02/18/2022] Our review paper “Reinforcement Learning for Selective Key Applications in Power Systems: Recent Advances and Future Challenges” was accepted for publication in IEEE Transactions on Smart Grid.
[01/2022] I passed my PhD dissertation defense!!!!
[12/2021] I received the Outstanding Student Paper Award in 2021 IEEE Conference on Decision and Control (CDC) for our paper “Safe Model-Free Optimal Voltage Control via Continuous-Time Zeroth-Order Methods”, which is also a finalist for the Best Student Paper Award.
[11/02/2021] Check our new preprint “Improve Single-Point Zeroth-Order Optimization Using High-Pass and Low-Pass Filters”. This is an interesting work that borrows the idea of high-pass and low-pass filters from extremum seeking control to design new single-point zeroth-order optimization algorithms with significant performance improvement.
I co-chaired a session “data-driven optimization and control for power systems” in 2021 INFORMS Annual Meeting, Oct. 24-27, Anaheim, California, USA.
