Professional Experience

Dr. CHENG Xiyu earned a PhD in Biochemical Engineering from Institute of Process Engineering, Chinese Academy of Science, China in 2011. He then joined the Department of Chemical and Biomolecular Engineering, National University of Singapore as a Research Scientist until 2013. Dr. CHENG is currently an Associate Professor in the College of Life Sciences and Bioengineering, School of Science, Beijing Jiaotong University. His research interests lie in two major areas, one focusing on the antitumor biomaterials, particularly in the area of developing efficiency multi-modality therapy for tumors via magnetic particles, biological vesicles and other nano- and micro-materials while another in the field of microbial biotechnology derived by advanced synthetic biology either for bio-energy or for wastewater treatment. He has published more than 30 papers in high-level academic journals, with h-factor of 14, and obtained 5 authorized Chinese invention patents.

Research Field

Nano- & micro-materials and tumor diagnosis and treatment: preparation of magnetic particles, biological vesicles and other nano- and micro-materials and their application in tumor diagnosis and treatment.
