Prof. Haikun Jia is currently a tenure-track Associate Professor in the School of Integrated Circuits at Tsinghua University, Beijing, China. He received B.S. and M.S. degrees in electronics science and technology from Tsinghua University in 2009 and 2015, respectively. From 2015 to 2016, he was a Post-Doctoral Researcher at the Hong Kong University of Science and Technology (HKUST). From 2016 to 2019, he was with a startup company in Silicon Valley, working on the high-speed SerDes IC design for the next-generation Ethernet. Since 2020, he has been a Faculty Member of the School of Integrated Circuits at Tsinghua University, Beijing, China. His research interests include millimeter-wave integrated circuits, systems, and high-speed wireline transceivers.

Group Openings: Our group has openings for 3-4 PhD/Master students every year and regularly recruits postdocs with a related background in RF/mm-wave/THz and mixed-signal integrated circuits and system design, and high-speed SerDes design. Undergraduate students are also encouraged to participate in our research. For more information, please email jiahaikun@tsinghua.edu.cn
