I am an Assistant Professor of Electrical and Computer Engineering and a member of WINLAB at
Rutgers University. My research interests are at the intersection of human-computer interaction, mobile computing, and security engineering. I am particularly
interested in privacy, social computing, context-aware communications, and (un)distracted driving.
There is always room
for exceptional students in my group. If you are interested, send a note about what have you done beyond classwork: email@example.com.
