Summary: I'm currently working for Samsara as an Applied Scientist in the ML Science organization. I obtained my Ph.D. in Informatics from College of IST at the Pennsylvania State University. My advisor is Prof. Wang, James Z. I have extensive research experience in Computer Vision, Deep Learning, and Data Science, especially their application in the IoT, healthcare, and medical domains.

I received my B.S.E. in Data Science at University of Michigan, class of 2019. I also hold a B.S.E in Electrical & Computer Engineering at Shanghai Jiao Tong University, Class of 2019, under the UM-SJTU Joint Institute.

Research

My thesis research is on the DeepStroke project that aims to advance stroke emergency triage and patient self-assessment with mobile AI. I have lead several publications in major venues and participate in NIH proposal writing.
I have 7 years of academic and industrial research expertise in Computer Vision and Data Science, with their applications in healthcare, finances, and education.
Hands-on experience with state-of-the-art Multimodal Deep Learning, Medical AI, and Foundation Models. Previously, I collaborated on (1) vision-language understanding of placenta and (2) bodily expression of emotion projects.
I have strong passion about methods and techniques for data to “talk” themselves, for models to improve fairness and usability, and for AI products to make positive impacts to the society.
