About me

I am currently an Assistant Professor in the Department of Electrical Engineering at the Indian Institute of Technology, Dharwad, India. I work in the broad area of wireless communications. I am currently interested in obtaining energy-efficient, near-optimal algorithms for delivering fresh information in emerging wireless networks with provable performance guarantees. I am also working on optimization of energy harvesting wireless networks and on application of deep-learning framework for achieving low-latency communications.
