I am an Associate Professor in the Software and Societal Systems Department (S3D) and Human-Computer Interaction Institute (HCII) in the School of Computer Science at CMU. I lead the Smart Sensing for Humans (SMASH) Lab at CMU. My research interests are Human-Computer Interaction, Ubiquitous Computing, Sensing, Signal Processing, and Applied Machine Learning. I regularly collaborate with mechanical and biomedical engineers, doctors, nurses, community health workers, and patients and their caregivers. Some of my inventions are deployed in clinics worldwide, licensed to several companies, and are part of commercial products. I received my Ph.D. in Computer Science and Engineering from the University of Washington, an M.S. in Computer Science from the Georgia Institute of Technology, and a B.Tech. in CSE from GGS Indraprastha University, India.
