Actively seeking faculty positions

Sijie Ji

Schmidt Science Fellow @ Caltech

I am currently working with Prof. Wei Gao in the Division of Engineering and Applied Science at Caltech. I also hold a joint appointment with UCLA, working with Prof. Mani Srivastava.

I obtained my Ph.D. from Nanyang Technological University in 2023, under the guidance of Prof. Mo Li.

Broadly interested in sensing, deep learning, ubiquitous computing, and their applications in digital healthcare, cyber-physical systems, and next-gen AIoT.
