Dr. Sunyaev is director of the Max-Planck-Institut für Astrophysik, one of the leading institutions in the world for theoretical astrophysics research, and a member of the Russian Academy of Science.
Dr. Sunyaev and Yakov B. Zel'dovich of the Moscow Institute of Applied Mathematics developed the theory for the evolution of density fluctuations in the early universe. They predicted the pattern of acoustic fluctuations that have been seen in the microwave sky and in the large-scale distribution of galaxies. They proposed what is known as the Sunyaev-Zel'dovich effect, which is due to electrons associated with gas in galaxy clusters scattering the cosmic microwave background radiation.

In addition, he has worked on a model of accretion on to black holes, and important studies of the early universe. He is a winner of the Heineman Prize (2003) and the Crafoord Prize (2008).
