About me

I am a Ph.D. student in Computer Science at Emory University, advised by Prof. Wei Jin. Previously, I was fortunate to work with Prof. Zhiguang Cao and Dr. Yining Ma. I received my M.S. from the National University of Singapore and completed my undergraduate studies at Nankai University.

My current research focuses on machine learning for time series data. I spend time thinking about:

  1. whether there exists a universal architecture for time series, or whether domain-specific inductive biases are necessary;
  2. what minimal inductive biases make vanilla Transformers work well on time series;
  3. what are the right scaling recipes for time series models (model size, data, context length, or something else);
  4. what knowledge transfers across temporal domains, and why large-scale pretraining helps on unseen data;
  5. how specialized numerical time series models should collaborate with general-purpose LLM agents.

Previously, I worked on neural combinatorial optimization, where we explored how AI can help solve NP-hard decision-making problems in the real world.
