Associate Professor · University of Pittsburgh
Longfei Shangguan
I lead the Pittsburgh Experimental Research Group (PERG). Our work sits at the intersection of computing, sensing, and wireless communication to enable robust, human-centered intelligent systems.
Before joining Pitt, I worked as a postdoctoral research associate at Princeton and later as a senior researcher at Microsoft. I received my PhD in Computer Science from HKUST in 2015.
