James J. Hickman, Ph.D., serves as the Chief Scientist at Hesperos, Inc., driving the development of their pioneering "Human-on-a-Chip" platform. Notably, he introduced the first serum-free, defined culture system for neuronal systems in 1995 and expanded it to include various cell types such as cardiac, muscle, glia, endothelial, hepatocytes, bone marrow, cancer, and epithelial cells. His work established a common media system with high test/retest reliability, vital for commercial applications. With a Ph.D. from MIT in Chemistry, Dr. Hickman is a Fellow and Board Member of the American Institute for Medical and Biological Engineers (AIMBE), and his contributions encompass numerous patents, publications, presentations, and chapters in the field of biomedical engineering.
