About Me

Hello, I’m JIANG Zhihan. I'm currently a Ph.D. candidate in the IoT Lab at the University of Hong Kong, under the supervision of Dr. Edith C.H. NGAI. I received the bachelor and master degrees in Computer Science and Technology from Xiamen University under the supervision of Dr. Longbiao CHEN.

My research interests lie in Data Analytics & Visualization, Ubiquitous Computing, and Mobile Computing. Currently, I mainly work on mobile analytics systems for healthcare.

I always welcome the opportunity for research collaboration and I'm eager to explore potential research ideas. If you're interested, please feel free to drop me an email.
