Dr. Ramchandran received his PhD from the Georgia Regents University, Augusta, Georgia, USA in 1997. Currently, he is a tenured Professor at the Medical College of Wisconsin, Milwaukee, WI. He is the Patrick J. and Margaret G. McMahon Professor in Obstetrics and Gynecology, and Vice Chair for Research in the Department of Obstetrics and Gynecology, in addition to his responsibilities as the Director of the Developmental Vascular Biology Program, and Director of the Zebrafish Drug Screening Core. His research has included investigation of the basic mechanisms of blood vessel formation in vertebrates, and how those vessels contribute to diseases. His lab studies developing zebrafish and mouse embryos to gain insights into vascular conditions associated with children, such as hemangiomas and solid tumors. In addition to studying blood vessel formation, his lab is also developing tools for performing drug screens using zebrafish embryos, which will identify targets and potential drug leads for treating pediatric vascular conditions.
Based on this research and fellowship training he/she has received several awards and honors. Some of them include the 2002 NCI Scholar Award, and the 2013 Distinguished Alumnus Award at Georgia Regents University. He serves on the editorial board of Vascular Cell, Indian Journal of Clinical Medicine and PLoS ONE journals, and is an expert reviewer for several leading journals including Cancer Research, FASEB, Journal of Biological Chemistry, Nature, Blood, PNAS, Circulation Research, and Nature Communications. He has authored 49 research articles/books, and is a member of the American Association of Cancer Research, American Association of Anatomists, American Heart Association, the North American Vascular Biology Association and the Society for Developmental Biology.

Research Interest

His research interests include: Developmental Vascular Biology: Vasculogenesis and Angiogenesis Mechanisms in Zebrafish and Mice, Vessel and Axon Guidance, Zebrafish Chemical Biology, Translational Models of Disease, Tumor Metastasis.
