Radha Kumaran

PhD Candidate in the Four Eyes Lab at the UCSB Computer Science department, advised by Professor Tobias Höllerer. I have a BE in Computer Science and Engineering from R V College of Engineering, and interned at the Indian Institute of Science and IBM during my undergraduate.


I work in human-computer interaction, primarily in the areas of affective computing and mixed reality. I'm interested in developing emotion- and cognition-aware personal computing interfaces that can adapt to user and environment context, to enable seamless interactions in always-on personal computing.
