Short Biography:
I am an Associate Professor at School of Mathematical Sciences, University of Science and Technology of China (USTC).
From 2009 to 2015, as a Research Fellow, I spent five years in Yeow Meng Chee's group at the Nanyang Technological University and one year in Ian M. Wanless's group at Monash University. I obtained my Ph.D. degree in 2009 from Zhejiang University, under the supervision of Prof. Gennian Ge. For more information please see my Curriculum Vitae.
I am also a member of the Interdisciplinary Research Group of Combinatorics and Information Theory (组合数学与信息交叉科学研究团队). We are looking for motivated postdoctoral researchers or doctoral students keen in working on combinatorial design theory or coding theory. Interested candidates are welcome to send your resume to Prof Gennian Ge (gnge@zju.edu.cn) or me to apply.
Research Interests:
Combinatorial design theory such as Steiner systems, Room squares, group divisible designs and Latin squares;
Combinatorial structures or decompositions of graphs with applications in bioinformatics, network, data storage, coding theory and quantum information theory
Awards and Professional duties:
Kirkman Medal for year 2012
On Editorial borad of Journal of Combiantorial Designs
