I am an Assistant Professor in the School of Computing at the National University of Singapore. I lead the Wireless, Embedded Intelligence, Sensing and Emerging Technologies (WEISER) group. We are interested in wireless embedded systems. We like to engineer systems, often at the intersection of electronics, communication and computer science.

Previously, I was a Postdoctoral Scholar at the Department of Electrical Engineering and Computer Science (EECS) of the University of California, Berkeley. I was affiliated with the Lab11. My postdoctoral training was partially funded through the endowment of 2019 ABB Research Award in Honor of Hubertus von Grünberg awarded to my doctoral dissertation.

Even before, I was a doctoral student at the Department of Information Technology of the Uppsala University, Sweden (Est in 1497!). My doctoral dissertation tackled the challenges of enabling sustainable deployment of embedded systems. In particular, through design of energy-efficient radio transmitters. I was also a software engineer at NXP Semiconductors.
