The research of my group at Cardiff University can be broadly divided into four areas: III-V integration on silicon; Quantum dots and devices; Nanowires and integrated materials; Unconventional epitaxy for disruptive integration technologies. 

We work closely with the Institute for Compound Semiconductors (ICS) and EPSRC Future Compound Semiconductor Manufacturing Hub.

We are looking for a postdoctoral researcher in Compound Semiconductor Fabrication and Characterisation (Closing date: Tuesday, 10 August 2021)


I received the B.S. degree in Microelectronics from Peking University, Beijing, China in 2009, and Ph.D. degree in Electronic and Computer Engineering (ECE) from The Hong Kong University of Science and Technology (HKUST) in 2014. Between 2014 and 2018, I was with the ECE Department of HKUST, first as a Research Associate (2014-2015), and then as a Research Assistant Professor (2015-2018). In March 2018 I joined Cardiff University as a Lecturer.
