Ang Li

I am currently a Research Associate in Qualcomm AI Research. Before joining Qualcomm, I obtained Ph.D. from Duke University under the supervision of Professor Yiran Chen and Hai “Helen” Li in Duke CEI Lab. I will join the Department of Electrical and Computer Engineering at University of Maryland, College Park as a tenure-track assistant professor. My research interests lie in the intersection of machine learning and edge computing, with a focus on building large-scale networked and trustworthy intelligent systems to solve practical problems in a collaborative, scalable, secure, and ubiquitous manner.

Openings: I’m looking for highly motivated Ph.D. and master students, and research interns to join my group. If you are interested, please send an email to angliece@umd.edu with you CV and transcripts attached.
