Rajat Mittal, M.S., Ph.D.
Joint Appointment in Medicine
Research Interests: Computational ?uid dynamics; Hemodynamics; Bio?uid dynamics; Fluid-structure interaction; Biomedical engineering
Dr. Rajat Mittal is a professor of medicine at the Johns Hopkins University School of Medicine and professor of mechanical engineering at the Whiting School of Engineering. His research focuses on developing computational methods to model a variety of physiological flows, with particular focus on cardiovascular, cerebrovascular and cardiac hemodynamics, and phonatory aerodynamics. Dr. Mittal also works as a core faculty member at the Johns Hopkins Institute for Computational Medicine and Institute for Data Intensive Engineering and Science.
Dr. Mittal received his undergraduate degree from the Indian Institute of Technology in Kanpur, India. He earned a master’s degree from the University of Florida and a doctorate in applied mechanics from the University of Illinois Urbana-Champaign. He completed postdoc research in flow mechanics at Stanford University.
Prior to joining Johns Hopkins in 2009, Dr. Mittal was director of the George Washington University Center for Biomimetics and Bioinspired Engineering and a professor at George Washington University.
Dr. Mittal was most recently honored with American Physical Society and American Society of Mechanical Engineers fellowships.

Research & Publications
Dr. Mittal conducts research in computational modeling of physiological fluid dynamics. He was trained as a fluid dynamicist, and has extensive background in computational fluid dynamics, turbulence, fluid-structure interaction, high-performance computing and biomechanics. For the past fifteen years, he has been developing computational methods to model a variety of physiological flows with particular focus on cardiovascular and cardiac hemodynamics, and phonatory aerodynamics. A hallmark of his research is the development of multiphysics models that couple a variety of physical domains such as fluid flow, solid mechanics, acoustics and biochemistry, in order to provide unique modeling capabilities and insights into the biophysics of organ function in health and disease. Current research focuses on CT based diagnostics for coronary artery disease, biophysics of cardiac auscultation and mechanisms for thrombogenesis, prosthetic heart valves and cerebral aneurysms.
