Maciej Lewenstein (born September 21, 1955 in Warsaw), is a Polish theoretical physicist, currently an ICREA[1] professor at ICFO – The Institute of Photonic Sciences[2] in Castelldefels near Barcelona.
He graduated at the Institute for Theoretical Physics at Warsaw University in 1978, with his diploma thesis about the superradiance phenomenon written under the supervision of Prof. Kazimierz Rzążewski [pl].
In the years 1984-1986 he spent long term visits as a postdoc at Essen University with Prof. Haake working on statistical physics of disordered systems.
After returning to Poland and becoming a faculty member of the CFT, he habilitated in 1986 at the Institute of Physics in Warsaw with a thesis on cavity quantum electrodynamics and intense laser-matter interactions.
In 1992 he spent a six-month sabbatical at the Service de Photons, Atomes et Molécules (SPAM) of the Commisariat a l’Energie Atomique in Saclay.
In 1994 he spent six months at the Institute for Theoretical Atomic and Molecular Physics at the Harvard-Smithsonian Center for Astrophysics, continuing studies of ultra-cold gases with R. Glauber.
In 2005 he moved to Spain as ICREA professor to lead the quantum optics theory group at the Institut de Ciències Fotòniques (ICFO) in Castelldefels.
He has supervised over 40 post-docs and provides services as a reviewer and evaluator for several national and international research funding agencies (EU, NSF, EPSRC, Royal Society, DFG, AvH Foundations and their counterparts in Australia, Israel etc.)
