I am a fifth-year PhD student at Uppsala University, Sweden. My advisors are Professor Thiemo Voigt (SICS and Uppsala University, Sweden) and Professor Luca Mottola (Politecnico Di Milano, Italy and SICS, Sweden). I am part of the Uppsala Networked Objects (UNO) research group. I also actively collaborate with Networked Embedded Systems (NES) group at Swedish Institute for Computer Sciences (SICS).

My research interests are in designing novel sensing and communication mechanisms for low-power systems. To that end, I had developed the first sensor testbed in the world equipped with electronically steerable directional antennas. For the past two years, I have been fascinated with ultra-low power sensing and communication. My current focus is to devise novel sensing and communication mechanisms based on visible light and backscatter communication to enable new battery-free applications!

Before starting to work as a PhD student, I graduated with Bachelors in Information and Communication Technology (equivalent major: Computer science, minor: Electronics and Communication) in 2011. As an undergraduate, and later as a research engineer, I worked with Professor Prabhat Ranjan and developed wireless sensor nodes for wildlife monitoring and seismic detection, here (1,2,3) are some the pictures of the node that I designed! I also worked for a short duration at Qualcomm (formerly NXP).
