Duvvuri Subrahmanyam is an Assistant Professor of Aerospace Engineering at the Indian Institute of Science (IISc), where he leads the Turbulent Shear Flow Physics and Engineering Laboratory (TSFPEL). His research interests are broadly in the area of aero/fluid dynamics, with a focus on turbulent shear flows in both incompressible (subsonic) and compressible (supersonic, hypersonic) regimes. Both fundamental and applied aspects of these subjects are of interest to him. During the Covid-19 crisis, TSFPEL played a lead role in an effort at IISc to develop novel low-cost high-functionality medical ventilator technology. He tweets as @mangaloreman.
