Prof. Dr. Hiroki Yokota is a Professor of Biomedical Engineering at the Indiana University Purdue University Indianapolis and an Adjunct Professor of Anatomy, Cell Biology and Physiology at the Department of Anatomy, Cell Biology, and Physiology at Indiana University School of Medicine. He is also a Full member of the Tumor Microenvironment and Metastasis. He received his B.S., M.S., and Ph.D. in Astronautics from the University of Tokyo, Japan, in 1978, 1980, and 1983, respectively. In 1993, he obtained a Ph.D. in Molecular, Cellular, and Developmental Biology from Indiana University Bloomington and continued his post-doctoral studies at the University of Washington School of Medicine from 1993 to 1998. His current research interest is the effect of mechanical and electrical stimulation on the growth and migration of breast cancer cells. He is interested in developing an adjuvant therapy useful for the treatment of bone/brain metastases associated with breast cancer. He is also interested in tumor-bone interactions, in particular, the role of osteocytes and chondrocytes in the presence of mechanical stimulation.
