About me

My research is in machine vision and learning for assistive and autonomous technologies. I work to enable mobile systems to understand and interact with humans, with a specific focus on two domains in mobility and transportation – autonomous driving and assisted navigation. At CMU, I'm fortunate to collaborate with Kris Kitani (Computer Vision Group) and Chieko Asakawa (Cognitive Assistance Lab).
