professional experience                

 

group leader                                                                                                                2007-present

reneuron inc (merged with amcyte)-santa monica, ca                   

  contribute research expertise as well as dynamic leadership skills toward proficiently steering multiple projects focused on culture, 3d-maintenance in algenate microcapsule and characterization of genetically modified human fetal neuron, hepatocytes and pancreas cells; key emphasis on culture medium development.

  proficiently manage facility operations to maximize real-time qrt-pcr, immunocytochemistry and animal experiment performance.

 

group leader/senior scientist, pancreatic/hepatic stem cell biology                              2001-2007

amcyte diabetes inc.-santa monica, ca

  proactively led human islet isolation project team, facilitating a cohesive, collaborative and self-directed teamwork environment conducive to generating enhanced productivity, efficiency and quality of job performance.

  concurrently gained extensive experience in islet isolation by working with over 150 pancreases; acquired working knowledge of gmp/glp and effectively developed human pancreas cells culture methodologies.

  successfully initiated and developed hepatocytes 3d culture in alginate encapsulated setting and developed expertise in managing cell therapy research portfolio for diabetes and acute liver failure.

  steered cell/molecular biology/animal experiment division; oversaw animal experiment core facility targeting the development of diabetes and liver failure models and directed real-time quantitative pt-pcr core facility and assay development projects.

 

postdoctoral fellow, cancer cell/molecular biology                                                        1996-2001

dept. of hematology and oncology , children s hospital of los angeles/university of southern california

  spearheaded projects focused on the regulation of human tissue inhibitor of metalloproteinases-2 (htimp-2) promoter; successfully identified the sequence motifs for htimp-2 basal activity and its activation by cyclic amp.

  facilitated cancer cell growth suppression projects, resulting in discovery that fibrillar collagen inhibits cell cycle progression in malignant melanoma cells and further, that this inhibition involves adhesion through the a1ß2 integrin and up-regulation of the cyclin inhibitors p15ink4b and p21cip1.

 

postdoctoral fellow, immunology/molecular biology                                                       1995-1996

relocated to u.s., published research articles and concentrated on ph.d./academics                 1988-1994

 

assistant professor, dept. of pharmacology                                                                  1983-1987

school of medicine, shanghai medical university, china

  presented pharmacology lectures to 3^rd-year medical students, 4 semesters.

  conducted study on neuropharmacology targeting effects of ephedrine and spardine on the neuromuscular junctions of rat diaphragm.
