About Me

I am currently a Ph.D. student at UCLA, advised by Prof. Cho-Jui Hsieh. My research area is Efficient and Automated Machine Learning methods. Besides research, I am also open to venture capital and entrepreneurial opportunities.

I obtained my B.S. degree (dual) in Computer Science and Statistics at the University of Michigan, with the highest distinction. During this period, I interned at Microsoft Research and Sensetime on machine learning and computer vision, as well as helped a startup to develop its prototype robots. Prior to that, I worked on quantitative investing at Shanghai Key Laboratory of Finance.

Research Overview

I study the problem of AI for AI. The goal is to leverage the power of A.I. to automatize the development of itself. For the past two years, I have mainly focused on a prominent direction under this concept - Automated Machine Learning (AutoML), which includes:

  • Neural Architecture Search (NAS)
  • Learning to Optimize (L2O)
  • Dataset Compression (DC)

AutoML is a highly general field with connections to many, if not all, facets of machine learning and its applications. Because of this, I am (or was) also involved in several other related topics such as:

  • Transformers (Efficient Inference, Multi-Modality, e.t.c.)
  • Scalable Graph Learning Algorithms
  • Adversarial Robustness
  • Federated Learning
