Other Expertise

As an overseas Chinese, he received an award in 2004 from NSFC to promote international collaboration. He has served as a reviewer/adviser for granting agencies such as NIH, NSF (USA), Cancer Research UK, Canada FFI, Swiss NSF, Hong Kong, NSFC (China) and STCSM (Shanghai), and as an editorial board member for Stem Cells (USA), Regenerative Medicine (UK) and Cell Research (Shanghai, China). Dr. Cheng is a member of the International Committee for the International Society for Stem Cell Research, in the Stem Cell Policy and Ethics Program in JHU, and in the (international) Hinxton Group.

Future Research

Continuing laboratory research on human embryonic stem (ES) cells and hematopoietic stem cells (HSCs): focusing on molecular mechanisms controlling self-renewal vs. differentiation, and on genetic modification for directed differentiation and for creating human disease models based on human ES or other typed of pluripotent cells that are genetically amenable. These include the derivation and use of human iPS cells containing a mutation as found in human diseases such as sickle cell anemia. We are also conducting engineering projects using lentiviral vectors for genetic modulation, iPS cell derivation, and for in vivo imaging of transplanted cells in animal models.

Industrial Relevance

Before Dr. Cheng joined the Johns Hopkins faculty in 1999, he worked as group and project leader in two biotech companies for more than four years. He worked for Systemix Inc. (acquired by Novartis), one of the first stem cell biotech companies. Subsequently, he worked for Osiris Therapeutics, Inc., a company in Baltimore commercializing mesenchymal stem cells. At Hopkins, Dr. Cheng's group continues stem cell research to improve transplantation and cell/gene therapy for treating a variety of diseases. With 17 year experience in stem cell research and industrial background, Dr. Cheng is dedicated to translate laboratory research into clinical applications. He occasionally serves as an advisor and consutant for biotech and healthcare industry such as GLG.
