Sriram Rajagopal Ramaswamy (born 10 November 1957) FRS[1] is Director of the Tata Institute of Fundamental Research (TIFR) Centre for Interdisciplinary Sciences in Hyderabad, and a Professor (on leave) at the Indian Institute of Science, Bangalore.[2][3][4]

Education

Ramasway was educated at the University of Maryland where he was awarded a Bachelor of Science degree in Physics with high honours in 1977.[4] He completed his PhD in theoretical physics at the University of Chicago, graduating in 1983.[5] He completed postdoctoral research at the University of Pennsylvania.[6]

Research

Ramaswamy is a theoretician whose research investigates nonequilibrium statistical physics, soft matter, condensed matter physics and biological physics.[2] His research helped found the field of active matter, which studies the collective behaviour of objects, such as motility, that convert local energy input into autonomous motion.[1]

He is widely known for formulating the hydrodynamic equations[7][8] governing the alignment, flow, mechanics and statistical properties of suspensions of self-propelled creatures, on scales from a cell to the ocean.[9] Key predictions—that macroscopically aligned flocks of swimming bacteria are impossible, and that the addition of swimmers to a fluid can make the viscosity arbitrarily small—have been confirmed in recent experiments. His insight into nonliving imitations of self-propulsion has led to design principles for chemotactic colloids, the first experiments observing giant number fluctuations in flocks, and the creation of flocks with a tiny minority of motile constituents.[1][10][11][12][13]

Awards and honours

Among the awards he has received for his research are the Shanti Swarup Bhatnagar Prize for Science and Technology in 2000 and the Infosys Prize in 2011.[6] He was elected a Fellow of the Royal Society (FRS) in 2016.[1]
