I am the Founder of Marbella, which provides customized (Generative) AI solutions to companies in the traditional industries. Marbella is currently incubated at the Harvard Innovation Labs and here is a recent pitch!

I have been a Postdoc Research Fellow in AI at Harvard University. Most recently I did a Ph.D. in Computer Engineering at the University of Pittsburgh working on Machine Learning with applications in Healthcare, Biology,  Moblie,  Finance,  Social Science, and Operations.

Previously I did my B.S. in Computer Science from Peking University with a Thesis at Carnegie Mellon University. I also did a Master's study at Cornell University.

I am looking for full-time opportunities in both academia and industry (Tech, Finance, Healthcare, etc.)  Let me know if you have any exciting opportunities!

My current research interest lies in Representation Learning, Computational Oncology, Knowledge Graphs, Causal Machine Learning, Clinical Decision Support, Reinforcement Learning,  Artificial Intelligence of Things (AIoT), and Multimodal Learning.  I also have a keen interest in technology commercialization and entrepreneurship. 

I love to collaborate with people from diverse backgrounds so feel free to get in touch!
