About me
I am currently a Postdoctoral Researcher in the Department of Statistics and Data Science at the University of Pennsylvania, jointly mentored by Prof. Edgar Dobriban, Prof. Ian Barnett, and Prof. Pratik Chaudhari, working on model calibration and uncertainty quantification of machine learning models. Before that, I was an applied scientist at Amazon.
I obtained my Ph.D. in 2022 from the Department of Statistics at Purdue University, supervised by Prof. Faming Liang. I received my bachelor’s degree in 2017 from the Department of Mathematics in Chu Kochen Honors College, Zhejiang University.
Research Interests
I am interested in connecting statistical theories with advanced Machine Learning models, and with theoretical guidance, develop effective methods to improve practice. Some topics that I have worked on include:Sparse Deep Learning: Consistency, High Dimensional Variable Selection, Network Pruning.
Bayesian Statistics: Bayesian Neural Network, Posterior Concentration, Markov Chain Monte Carlo.
Uncertainty Quantification: Model Calibration, Asymptotic Distribution.
