Biosketch

Alexei A. Starobinsky is a theoretical physicist recognized for his work in gravity, cosmology and astrophysics. He is known particularly as one of the authors of the theory of a quasi-de Sitter (inflationary) stage preceding the hot Big Bang (radiation dominated stage) in the early Universe (for his papers beginning from 1979), as well for his works on super-radiance and creation of particles by rotating black holes (1973). He was born in Moscow, USSR, in 1948 and grew up there, He graduated from the Moscow State University in 1972 with a MSc degree in physics and then was a postgraduate student at the Landau Institute for Theoretical Physics of the USSR (now Russian) Academy of Sciences, Moscow - Chernogolovka, where he got his PhD in theoretical and mathematical physics in 1975. Since that time he was a staff member at this institute keeping positions of a researcher, senior researcher, Science secretary, leading researcher, Head of the Department, Vice-Director and principal researcher in possession. He also spent much time as a visiting professor at the University of Tokyo and the Yukawa Institute for Theoretical Physics, Kyoto, Japan, Ecole Normale Superieure, Paris, France; Institute of Theoretical Physics, Utrecht University, Netherlands; Inter-University Center for Astronomy and Astrophysics, Pune, India and other universities in different countries. He is member of the Russian Academy of Sciences (Correspondent Member – 1997, Full Member – 2011), the Academy Leopoldina—the German National Academy of Sciences (2010), the Norwegian Academy of Science and Letters (2014), a Foreign Fellow of the National Academy of Sciences, India (2013) and the Indian National Science Academy (2017), and a Fellow of the American Physical Society (2011). He is also a recipient of the Kavli, Gruber, Friedmann and Tomalla prizes and Gold Sakharov, Oscar Klein, Amaldi and Friedmann medals for his research.
