Postdoc @ MIT CSAIL. Previously, PhD @ MIT DMSE, intern @ DeepMind & Google X

Find more about me in these platforms.

Welcome! I am a postdoc in Artificial Intelligence Laboratory (CSAIL) at MIT. I am co-advised by Tommi Jaakkola and Regina Barzilay.

Research interests: I am broadly interested designing physics motivated machine learning algorithms for solving real-world problems related to material design, drug design, and other engineering domains. I study how domain-specific inductive biases can be incorporated into neural networks to improve generalizability and interpretability. I work closely with chemists, material scientists, and other domain experts to deploy machine learning algorithms to accelerate existing workflows and gain scientific insights.

Previously: I got my PhD in Materials Science and Engineering at MIT in 2020, advised by Jeffrey C. Grossman. I got my BS in Chemistry at Peking University in 2015. I was a research intern at DeepMind, working with Pushmeet Kohli and James Kirkpatrick in 2019/05. I was a research intern at Google X in 2019/02.
