Biography

Dr He earned a Ph.D. in Bioengineering from the University of Washington in 2022 and worked there as a postdoctoral scholar afterward. Prior to that, he graduated with an M.S. in Physics from Tsinghua University and a B.E. from Nanjing University of Aeronautics and Astronautics. His current focus is on developing biomedical imaging and sensing technologies for low-cost, smart, mobile, and digital health monitoring. Dr He has published over 30 journal papers on this topic, with 17 as the first author, which have been cited over 500 times (H-index: 12, i10-index: 15). His research has been reported by over 20 media outlets, including Voice of America, Daily Mail, and Physics World. He has received numerous awards, including the National Graduate Scholarship and Academic Rising Award at Tsinghua University. He serves on the reviewer group of over 20 journals, such as Optica, Optics Letters, Biomedical Optics Express, and Optics and Lasers in Engineering.

Research Areas

Developing mobile and smart diagnostic technologies, particularly in biomedical imaging and sensing, to innovate in creating devices and methods for addressing clinical diagnostic needs, with a special interest in detecting ocular conditions and disease biomarkers.
