About Me

Photo

I am a 5th year Ph.D. student in the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison, supervised by Professor Xinyu Zhang. I received my B.Eng. degree in Optoelectronics Engineering from the Huazhong University of Science and Technology in China. My research spans over wireless networks, mobile sensing, indoor localization, internet-of-things (IoT), cross-layer system design and energy optimization. I design, prototype and evaluate sensor hardware and software (from firmware, low-level drivers to complete Android Apps). I also design and evaluate signal processing algorithms, especially under time and energy constraints.

I am currently visiting University of California, San Diego.

I am currently seeking tenure-track faculty positions. Here is my CV. You are welcome to email me if interested.

NOTE: Due to patent considerations, I am unable to share most of my implementation work (code, hardware design, etc.) in public. If you are interested in collaboration or commercialization, please drop me and Prof. Xinyu Zhang an email. Press inquiries are also welcome. Thanks for your interest!
