PhD Student, School of Computing, National University of Singapore
I’m currently a PhD student in the Weiser Group at the School of Computing, National University of Singapore (NUS), advised by Prof. Ambuj Varshney. My research focuses on designing energy-efficient wireless communication systems for embedded and IoT applications, with a particular emphasis on low-power receiver architectures. I’m also interested in novel approaches to wearable health sensing and in leveraging large language models (LLMs) for embedded systems applications, including system development and sensor data analysis.
