Mark L. Kahn is a Professor at the Perelman School of Medicine at the University of Pennsylvania, specializing in general cardiology. His research focuses primarily on signaling pathways in cardiovascular development and function, particularly those related to angiogenesis and platelet signaling. His laboratory is investigating how certain signaling mechanisms influence the development of lymphatic vessels and their interactions with blood vessels. Key projects include examining the regulation of lymphatic development by Syk and SLP-76 signaling, and the role of platelet-specific immune-type receptors in vasculature interactions. Kahn's work has significant clinical implications for understanding diverse vascular diseases. He is affiliated with the Cardiovascular Institute and has contributed to multiple high-impact publications in the field. In addition to his research, Kahn mentors students and postdoctoral fellows, guiding them in developing their scientific expertise.
