Hi~ I am currently a Postdoctoral Associate affiliated with MIT Energy Initiative at Massachusetts Institute of Technology, working with Prof. Andy Sun. I am also a research scientist at Singularity Energy, where I lead the development of carbon flow analysis and decarbonization solution products. I received my PhD degree from Harvard University in 2022, working with Prof. Na Li. I received my double B.S. degrees in engineering physics and economics from Tsinghua University in 2015, and my master’s degree in electrical engineering from Tsinghua University in 2017.
My research interests lie in learning, optimization, and control of human-cyber-physical systems, with particular applications to smart grids and smart cities. I am passionate about developing theoretical foundations and practically appliable 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.
[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.
[02/2023] I was selected as a finalist for the Ph.D. Dissertation Challenge at the IEEE PES Grid Edge Technologies Conference and Expo. Here is the banner.
[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.
