I am a fourth 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, and also actively collaborate with Networked Embedded Systems (NES) group at Swedish Institute for Computer Sciences (SICS).

My area of interest is in efficient communication and sensing for low-powered embedded devices and sensors used on IoT devices. I have extensive experience of over 6+ years in networking and programming sensors and embedded devices using technologies like Zigbee, Bluetooth, and WiFi. The results of some of the academic works have been published at flagship and highly selective conferences for IoT and embedded devices like ACM SenSys and ACM/IEEE IPSN .

Presently I am working on emerging communication technologies for IoT like Visible Light Communication and Backscatter communication. For example, one of our recent research efforts generate BLE and Zigbee packets at 1000X lower energy cost compared to conventional radio technologies using backscatter communication.

Before starting to work as a PhD student, I worked at NXP Semiconductors as a software engineer. 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 had the fortune of collaborating with the following people for some of my research work:
