About Me

I am a Ph.D. student in the Department of Electrical and Computer Engineering at the University of Maryland, College Park, supervised by Professor K. J. Ray Liu. I obtained my Bachelor's degree in Astrophysics from Peking University in 2015, and my Master's degree in Electrical Engineering from New York University in 2017. My current research interests include but not limited to signal processing,  millimeter waves, and the Internet of Things.

 

Education

 

PhD University of Maryland, College Park

Sep 2018 - Now

I am currently working towards the doctorate degree of Electrical Engineering at UMD under the direction of Professor K. J. Ray Liu .

MS New York University

Sep 2015 - May 2017

During my master's study, I was focusing on propagation models. I did mmWave measurements with Professor Ted Rappaport in 2016, in urban areas in NY and rural areas in VA. My thesis advisor, Professor I-Tai Lu helped me build a new propagation model at UHF accounting for street openings in urban street canyons.

BS Peking University

Sep 2011 - Jul 2015

Learning physics is fun and challenging. I studied pulsar stars with Professor Renxin Xu in the department of astronomy, and further did undergraduate dissertation on radio telescope feed design for pulsar star studies with Dr. Shengjin Jin in National Astronomical Observatories of China.

My Experience

 

Research Engineer 

Intelligent Fusion Technology, Maryland

May 2017 - Apr 2018

  • Analyzed ray tracing algorithms and developed programmes for ray tracing simulation in mmWave.

  • Investigated air-to-air and ground-to-air communication links.

  • Arranged plans and setups for mmWave UAV network measurements.

  • Helped applying machine learning to current propagation analysis, which improved the computing time and prediction accuracy.

Research Assistant & Teaching Assistant

NYU Wireless Center, New York

Jul 2016 - May 2017

  • Participated in 2016 NYU Wireless summer campaign for outdoor mmWave measurements. 

  • Based on data from industry, built a new propagation model accounting for street openings, clear improvements compared to current popular models.

Student Research Assistant

National Astronomical Observatories of China, Beijing

Sep 2014 - May 2015

  • Simulated the corrugated horn antenna model in High-Frequency Structural Simulator (HFSS), and expanded the original low-frequency model to a higher frequency, which was selected as a candidate feed antenna model for Five-hundred-meter Aperture Spherical Radio Telescope (FAST).

My Hobbies

 

Chess

I started playing chess at the age of five. I have earned many champions along the way. In 2003, I was select to participate in the World Youth Chess Championship on behalf of China.
During my master's study in New York, I was a member of the Marshall Chess Club and played games in many local tournaments.

Yangqin

In the first year of primary school, I met my Yangqin teacher Dr. Chen and became his first and the last student. I was awarded the first prize in the Global Chinese Music Festival in 2010. In college at PKU, I played leading Yangqin in the orchestra of Chinese Musical Institute (CMI) for four years, directed by Professor Bryan Bi. In 2012, we were invited to perform at the University of Edinburgh and Canongate Kirk.
