Ph.D of Swiss federal Institute of Technology in Lausanne. In the previous work Dr. Shen has developed a number of recombinant drug production technologies including insect cells transient and stable expression, the development of animal cell culture solution and large-scale production of cell culture feed. The laboratory of Dr. Shen has also maintained a world record in transient expression of protein. His technologies ensure that Cantonbio can develop bio-medicine and biological products independently without any other external technologies.
