Professional Experience

2017-Present: Professor, South China University of Technology

2013-2017: Professor, Huazhong University of Science and Technology

2011-2013: Postdoctoral Research Fellow, Harvard Medical School, Boston Children’s Hospital

Research Description

The Xiao group study mainly in the fields of cellular and molecular biomechanics, single molecule biophysics and engineering. Current research areas are: protein-ligand interactions, DNA and RNA assembly, high-throughput nanometer measurements and manipulation, mathematical modeling and quantitative analysis. The experimental techniques include: magnetic tweezers, optical tweezers, biomembrane force probe, fluorescent microscopy, genetic engineering, and chromatography. An project example is using high-throughput single molecule techniques to study the modulation of protein drugs on interactions of integrins and their ligands such as TGF-beta. We also study von Willebrand Factor and glycoproteins on platelets. We collaborate with a number of well-known universities and institutions, and a few enterprises. Our research will be of relevance for the prevention and treatment of cancer, immune and cardiovascular diseases.

Open Positions

Our group is always recruiting people who have the right capabilities and motivation to succeed in our research environments. Open positions are: a Research Associate Professor, a Research Assistant Professor or Lab Engineer, Postdoctoral Fellows, doctoral and master graduate students. Candidates should contact Prof. Xiao, and apply to the Biology and Biological Engineering.
