Kuang Yuan

I'm currently a 5th-year Ph.D. student of WiTech Lab and Semantic Signals Lab in the Electrical and Computer Engineering Department at Carnegie Mellon University. My advisor is Prof. Swarun Kumar and I also work closely with Prof. Justin Chan. I'm a recipient of the Qualcomm Innovation Fellowship. I received my bachelor's degree in Computer Science from the University of Science and Technology of China (USTC) in 2021 with the Guo Moruo Scholarship (The highest honor for USTC students).

My research interests lie in developing intelligent audio systems and sensing technologies, to promote human well-being in everyday life and support seamless human-computer interfaces. I design and build mobile systems which integrate sensors (acoustics, radar, IMU, etc.), real-time signal processing, and machine learning algorithms.

I'm a Research Scientist Intern at Meta Reality Labs during the summers of 2024 and 2025, working on audio technologies on smart glasses. I'm also fortunate to work with Prof. Jie Xiong during my undergrad years and the 2023 summer internship at Microsoft Research Asia.
