Senior Research Scientist
I am a Research Scientist in Amazon. I am working on a new technology initiative in a new area of focus for Amazon.
I have 12+ years of experience in networked embedded sensing systems research and engineering. I enjoy experimenting with sensing systems and designing sensor data processing algorithms. I have worked with various sensing modalities including electric and magnetic field, current and voltage, visible light, inertial, ultrasonic, and wireless sensing. I have an aptitude to work across different layers of the distributed sensing system stack, with focus close to the physical layer.
I got my PhD in Electrical and Computer Engineering at Carnegie Mellon University in July 2019. I was advised by Prof. Anthony Rowe and Prof. Bruno Sinopoli. I defended this: Localization, Beacon Placement and Mapping for Range-Based Indoor Localization Systems [PDF; Defense slides]. My thesis is heavily experimental. I deployed and evaluated all methods I present in my thesis in real-world settings. My work in indoor localization won the International Microsoft Indoor Localization Competition twice, in 2015 with an ultrasonic localization system and in 2018 with an UWB localization system.
During my PhD, I was affiliated with WiseLab and CyLab. I was fortunate to be part of the Terraswarm Research Center from 2013-2017, the NIST PSCR (Public Safety Communications Research) project for firefighter localization since 2017 and the CONIX Research Center from 2018. I interned at Texas Instruments and Apple during my PhD.
I received the Carnegie Mellon University William S. Dietrich II Presidential Ph.D. Fellowship in 2015 and the Samsung PhD Fellowship in 2016 .
Prior to my PhD, I received an MS degree from CMU in 2012 and a B.Tech degree in Electronics and Communication Engineering from the National Institute of Technology, Trichy, India in 2008. Between my B.Tech and MS degree, I worked as an IC Design Engineer at Analog Devices and an R&D engineer at Signals and Systems in India.
I enjoy traveling, being outdoors, and trying out new cuisines. I've had interesting experiences in France, Germany, Honduras (got my PADI scuba diving certification here!), India, Italy, Japan, Spain, South Korea, Sweden, Switzerland, Portugal (learnt surfing for a week!), Turkey, and the US over the past many years.
