Michał Bejger

Michał Bejger serves as an associate professor at the Nicolaus Copernicus Astronomical Center (NCAC) in Warsaw. Currently, Prof. Bejger is also in charge of leading the workgroup in a network for Gravitational Waves, Geophysics, and Machine Learning - COST ACTION G2NET.

He earned his doctorate in astrophysics at the Nicolaus Copernicus Astronomical Center in 2005. He completed his Postdoctoral Research Fellowship at Marie Curie Observatoire de Paris (2006-2007) and Nicolaus Copernicus Astronomical Center (2007-2008). Followed by his habilitation on astrophysical parameters of neutron stars a few years later (2013). In 2018, Prof. Bejger was a researcher at AstroParticule et Cosmologie (APC) [CNRS, Paris, France] in the gravitation group that studies were devoted to astrophysics and machine learning problems.

Prof. Bejger is a collaborator in projects devoted to the detection of gravitational waves and the construction of the LIGO - Virgo - KAGRA detector network. He is also involved in the work of the design and study team in the Einstein Telescope, where he is a coordinator on the Einstein Telescope Observing Science Board, in a panel studying various potential configurations of the future detector.

According to the Scopus database (Aug. 26, 2022), he is an author of 256 peer-reviewed articles that have been cited more than 35 000 times. The link to his publications included by the service NASA ADS can be found here.

Currently, Prof. Bejger is responsible for a research group composed of Dr. Paweł Ciecieląg, Dr. Filip Morawski and Dr. Jonas Pereira.
