Bio

Rajashekar is a Ph.D. student in Computer Science at the National University of Singapore, advised by Prof. Ambuj Varshney. My research lies at the intersection of low-power wireless systems, embedded sensing, and mobile computing. I am particularly interested in building energy-efficient communication architectures for embedded systems, with applications in health monitoring and ubiquitous IoT deployments. Prior to joining NUS, I completed a Dual Degree (B.Tech + M.S. by Research) in Electronics and Communication Engineering from IIIT Hyderabad, where I worked on IoT-based air pollution monitoring systems under the guidance of Prof. Sachin Chaudhari. I have industry experience as a Digital Design Engineer at Texas Instruments, where I worked on synthesis and timing analysis of SoCs in the SITARA family. I have also held research internships at Nokia Bell Labs, Cambridge, and the Neuromuscular Control & Biomechanics Lab at the University of Alberta, focusing on battery-free health sensing and wearable-based clinical activity monitoring, respectively.

Career Timeline
