About Me

Photo

I am currently working for Bitinno Technologies Inc., an IC start-up company based in San Diego. Previously, I was a postdoctoral researcher at University of California San Diego, working with Professor Xinyu Zhang and Professor Dinesh Bharadia. I received my Ph.D. from the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison in December 2017, supervised by Professor Xinyu Zhang. Before that, I received my B.E. in Optoelectronics Engineering from the Huazhong University of Science and Technology in China. My interests include wireless networks, mobile sensing, Internet-of-things (IoT), and low-power systems. I model, design, prototype, and evaluate end-to-end systems, from signal processing algorithms, circuits, firmware, software, to complete applications.
