Hi! I'm Siqi Zhang.

I'm a Ph.D. student at Semantic Signals Lab and Smash Lab at Carnegie Mellon University, advised by professor Justin Chan and professor Mayank Goel.

Prior to joining CMU, I obtained my B.E. degree at Tsinghua University, advised by professor Yuntao Wang and Haipeng Mi. I also worked as a research assistant at SciFi Lab, advised by professor Cheng Zhang.

My research primarily focuses on health sensing. I aim to build widely accessible, ubiquitous mobile systems that promote human well-being and seamlessly integrate into everyday life.
