About Me
I am an AI Research Scientist at Meta AI. I have been working on vision foundation models, multimodal language models, video understanding, etc.
During my PhD, I worked on improving deep learning for practical problems to serve the end users better, such as federated learning and personalization. Thesis title: Machine Learning with Many Users
I received my Ph.D. from the Department of Computer Science and Engineering (CSE) at the Ohio State University (OSU), where I was fortunate to be advised by Dr. Wei-Lun (Harry) Chao in 2019-2023. I was a visiting student in the Machine Learning Department at Carnegie Mellon University in 2018. During my undergraduate study, I worked with Dr. Shou-De Lin at National Taiwan University and Dr. Chi-Jen Lu at Academia Sinica.
