I received my B.Sc. and Ph.D. degrees in the School of Computer Science and Technology from USTC in 2014 and 2020, respectively, advised by Prof. Xin Yao and Prof. Ke Tang.
From Jan 2021 to Jan 2023, I was a Research Assistant Professor at the CSE Department of SUSTech.
From Jan 2023 to May 2024, I was a Visiting Professor, and later a senior scientist, at CFAR, A*STAR, Singapore, in collaboration with Prof. Yew-Soon Ong from NTU.
I am also a member of the Nature Inspired Computation and Applications Laboratory (NICAL) led by Prof. Xin Yao and Prof. Ke Tang.
Research Interest
Ultimately, I am obsessed with the theoretical foundations and practical approaches for the fully-automated design of optimization algorithms and learning models.
Now I am interested in:
Theoretical foundations of Learning to Optimize (L2O)
Learning scalable optimizers
Learning general-purpose optimizers
Evolutionary Large Learning Models
I am looking for self-motivated Master students, Ph.D. students, and Postdocs, working in the above research directions. If you are interested, please feel free to contact me via emails.
