Cathy Yang, MS, PhD, MD - Chief Operating Officer

Dr. Yang directed several research teams at Monsanto. She led CertiChem's research for Phase I and II grants to develop a robotic assay to detect estrogenic activity. Dr. Yang then led efforts to modify this assay for commercialization. She has over 20 peer-reviewed publications and a broad background in biology, from molecular biology through biochemistry, cell biology, systems physiology, anatomy, small animal surgery, and statistics. Dr. Yang received her medical degree from Hunan Medical University in China, and her Masters and PhD from the Institute Pasteur (Paris), France. She then worked for 4 years in Washington University in St. Louis, MO, as a postdoctoral fellow and directed research in cellular/molecular biology for Monsanto (St. Louis).
