Rajalakshmi Nandakumar

I am a Ph.D. candidate at University of Washington's, Paul G. Allen school of computer science and engineering. I develop computing technologies that enable novel applications across various domains including mobile health, user interfaces and IoT. My research focuses on developing and deploying computing technologies that can create an impact in the real world and improve the quality of life.

I work with Shyam Gollakota in the Networks and Mobile Systems lab at UW. Prior to UW, I was a research assistant in Mobility, Networks and Systems group at Microsoft Research India.

I will be joining Cornell Tech as an Assistant professor in the Spring. Students who are interested in Mobile Systems and Computational Health, email me.
