Research Interests
Broadly, my research interest mostly involves stochastic process such as mean-field type system and optimal transport. I’m interested in the theoretical study as well as the application in machine learning, generative modeling and sampling. Currently I have two specific topics that I intensively work on.
- Limit theorems for hetergeneous queueing systems
- Neural solver for Wasserstein geodesic or Schrödinger bridges
