He is also head of the Department of Observational Astrophysics at Astronomical Observatory, the head and project manager of the Optical Gravitational Lensing Experiment, and editor of the quarterly journal Acta Astronomica.


He graduated from the Faculty of Physics, University of Warsaw in 1980. In that same year, he was employed at the Astronomical Observatory of the University of Warsaw. He received his Ph.D. in 1988 and then completed a two-year Postdoctoral Research Associate at York University in Toronto, Canada.

In 2002, he won the prize of the Foundation for Polish Science (the so-called "Polish Nobel"). In 2009, he received a 2.5 million Euro grant from the program Ideas of the European Research Council that aims to support innovative research projects.


In April 1992, he launched the OGLE project, which aim at founding extrasolar planets using gravitational microlensing technique. Since then Udalski and his team made many important discoveries. In 1995-1996, he took part in the construction of the Warsaw Telescope at Las Campanas Observatory in Chile. In 2001, he built a wide-angle mosaic CCD camera with more than 65 million light-sensitive elements. Along with the OGLE team, he is also a co-discoverer of 14 extra-solar planets discovered by the technique of gravitational microlensing.
