I am a Postdoctoral Associate in the Electrical and Computer Engineering Department at Rice University working with Momona Yamagami.
I received my Ph.D. from the Computer Science Department at Stony Brook University. I was advised by Prof. Aruna Balasubramanian and worked in the NetSys Lab.
My research vision is to enable accessible computing interactions that move beyond touch-screens and voice. I work at the intersection of Mobile and Cyber-Physical Systems, Human-Computer Interaction (HCI), and Applied Machine Learning to develop lightweight interaction techniques using commodity wearables. My work primarily advances accessibility for users with visual impairments.
My research has been published at leading venues like MobiCom, SenSys, UbiComp, CHI, and ASSETS.
I have been fortunate to receive recognition for this work, including the CPS Rising Star, and Catacosinos Fellowship. I am also a recipient of the Paul Baran Young Scholars Celestini Prize India 2018 awarded by the Marconi Society for developing AirCognizer.
I have collaborated with Meta Reality Labs and Nokia Bell Labs during my PhD journey.
