We are delighted to welcome Dr. Avishek Ranjan to the IIT Bombay family. He joined the Department of Mechanical Engineering as Assistant Professor on May 2, 2018.He received his undergraduate degree (Bachelor of Electrical Engineering) from National Institute of Technology, Jalandhar in 2007, then he did his Masters by Research from Indian Institute of Technology, Madras in 2011 and Ph.D. from University of Cambridge, in 2015.Subsequently, after his B.tech he worked as an Assistant Manager in the camshaft-connecting rod manufacturing unit of Tata Cummins limited till 2008, as a research associate in Cambridge until April 2018.Dr. Ranjan is a recipient of Dr. Manmohan Singh doctoral scholarship awarded by St. John's College, Cambridge in 2011, Hardship award from Malaysian Commonwealth studies center, Trinity College, Cambridge in 2015 and Best data visualization prize in UKMHD meeting 2017.His research interests are in fluid mechanics with applications to the problems related to energy and environment and how the flow in the engine cylinder affects the air-fuel mixing and hence the performance & emissions. His doctoral and postdoctoral research work was based on understanding fundamental aspects of fluid flow under the effect of body forces due to the rotation, buoyancy and magnetic field which has applications mostly in geophysics, that is, atmosphere, oceans and the liquid outer core of the Earth. One of his current research interests is investigating the flow physics in liquid metal batteries which have been projected as the future of low-cost energy storage.His plans at IITB are to undertake several research projects related to his interests. He believes that challenging problems that we face today need several like-minded people working together with a common selfless goal and wants to collaborate with faculty in other departments at IITB.He believes in 'student-centered teaching and learning’ which focuses on encouraging active learning and achieving predefined learning outcomes with innovative assessment methods. He thinks including such methods can make learning more enjoyable. His primary goal is igniting a joy of learning and passion for research among the students hoping for a day when students will study not for high grades but just for the love of knowledge.In the spare time, he likes to read about topics in science (physics and mathematics) & spirituality (mainly eastern philosophy), and about the pioneers in these fields. Recent developments in neuroscience, in particular, those related to the hard problem of consciousness, also interest his very much. He is also fascinated by astronomy and likes to gaze at stars through his telescope.
