Subhra Datta is an Associate Professor in the Department of Mechanical Engineering Department, IIT Delhi. He studied Mechanical Engineering at IIT Kharagpur for his B. Tech. (2001) degree. He has an M.S. (2004) in Mechanical and Aerospace Engineering from Illinois Institute of Technology, Illinois, USA and a Ph. D. (2007) in Mechanical Engineering from Northwestern University, Illinois, USA. After his Ph. D., Subhra Datta worked for nearly three years (2007-2010) as a postdoctoral researcher at the Ohio State University, Ohio, USA. He works in the broad areas of microscale fluid mechanics, electrokinetics and microfluidics, primarily using a theoretical approach. His recent research has explored the consequences of micropatterning of surface charge, interfacial-chemistry and topography on flows confined to microscale or nanoscale dimensions. He is also interested in the electrochemistry of charge formation on microfluidic substrates and the convection, diffusion and electromigration of neutral and ionic species that accompany such flows. His research has applications in areas such as reduction of liquid-solid friction, electrokinetic pumping and energy conversion and microfluidic separations.
