Self-introduction：
Xi did his BSc in Experimental Medicine in Peking University Health Science Centre in Beijing, where he became interested in all the techniques used in biochemistry and molecular biology. After graduation, he joined Prof. Andrew Sharrocks’ lab at the University of Manchester as a PhD student, studying the DNA binding specificity of different Forkhead transcription factors. During this period, he discovered an evolutionarily conserved transcription factor complex that regulates G2/M cell cycle transition. After his PhD, he joined Dr. Sarah Teichmann’s group at the European Bioinformatics Institute as a postdoc to carry out single cell genomics research. In 2016, the Teichmann team moved to the Wellcome Sanger Institute. Xi moved with together with the group and became a Senior Staff Scientist. Xi has joined the Department of Biology in SUSTech as an Assistant Professor since 2019.

Research Interests：
(1) Single cell genomics techniques development.
(2) Use T cell development and stem cell differentiation as model systems to study roles of transcription factors and chromatin complex during cell fate decision and memory.
