I work at the intersection of low-power wireless systems, embedded sensing, and mobile computing. My research focuses on designing energy-efficient and scalable communication architectures for next-generation wireless embedded systems, with applications in health monitoring, ubiquitous computing, and the Internet of Things (IoT). I am particularly interested in developing ultra-low-power wireless transmitter-receiver architectures for embedded platforms, aiming to achieve operation at microwatt-level power consumption. I am part of the weiser lab at NUS advised by Prof. Ambuj Varshney.
