About me
I am a Postdoc Associate at MIT (since April 2023) advised by Prof. Richard D. Braatz. I got my Ph.D degree in March 2023 at IMT School for Advanced Studies Lucca advised by Prof. Alberto Bemporad. I was a software intern at Siemens Process System Enterprise (UK) from Jan. 2022 to Dec. 2022.
My current research interests include but are not limited to:
(1) Execution-time-certified and Fast QP solvers for real-time applications (e.g., MPC, CBF-CLF-QP);
(2) Koopman for optimal control;
(3) Model-based Safe RL;
(4) Real-time PDE control, etc.
