Professor Sriram Ramaswamy FRS
Sriram Ramaswamy is a theoretician with broad interests in nonequilibrium, soft-matter and biological physics. His research helped found the field of Active Matter, which studies the collective behavior of objects, such as motile organisms, that convert local energy input into autonomous motion.
He is widely known for formulating the hydrodynamic equations governing the alignment, flow, mechanics and statistical properties of suspensions of self-propelled creatures, on scales from a cell to the ocean. 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.
Sriram directs the TIFR Centre for Interdisciplinary Sciences in Hyderabad, on leave from the Indian Institute of Science, Bangalore. Among the awards he has received for his research are the Shanti Swarup Bhatnagar Prize (2000) and the Infosys Prize (2011).
