Arnab Rai Choudhuri is Professor of Physics at the Indian Institute of Science. He obtained his PhD from the University of Chicago in 1985. He is a theoretical astrophysicist who has worked on problems such as the formation of sunspots and the generation of the 11-year sunspot cycle by the dynamo process. He is one of the originators of the flux transport dynamo model, the currently favoured theoretical model of the sunspot cycle. Choudhuri is the author of two advanced textbooks, The Physics of Fluids and Plasmas: An Introduction for Astrophysicists (1998, Cambridge University Press) and Astrophysics for Physicists (2010, Cambridge University Press), as well as a popular science book, Nature's Third Cycle: A Story of Sunspots (2015, Oxford University Press).
