Research Summary
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.

Patient Ratings & Comments
The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
