Peter Raffai earned his MSc degree within the fields of physics and astrophysics at Lorand Eotvos University (ELTE), Budapest, in 2006, and his Ph.D. degree at ELTE in 2012. He worked as a postdoctoral researcher at Columbia University, New York, between Fall 2011 and Spring 2013.

He currently works as an assistant professor at the Department of Atomic Physics of ELTE. He has been a member of the LIGO Scientific Collaboration (LSC) since 2007, which is a world-wide community of scientists working on various fields of gravitational-wave physics. In particular, he has been leading the data analysis efforts of the LSC group at Eotvos University, called EGRG.

He has been demonstrating his active commitment to scientific outreach by giving public lectures, popularizing science through media appearances, and mentoring students at many academic levels. His research interests include gravitational-wave astrophysics, multi- messenger astronomy, compact objects, cosmology, and various aspects of data processing.
