About Karan

Karan is a 2nd year Ph.D. student at the Human-Computer Interaction Institute in the School of Computer Science at Carnegie Mellon University, advised by Dr. Chris Harrison and Dr. Mayank Goel. He is the recipient of the President of India Gold Medal. His research focuses on repurposing and augmenting sensors to revamp interactions and sensing modalities. He uses his background in applied machine learning, computer vision and cognition to solve problems in various domains, including health sensing, ubiquitous computing and interaction techniques. These often manifest themselves by leading to more intuitive human-computer interactions, elevating the context awareness of environments and enhancing health monitoring techniques.
