He earned his MSc degree in physics from Roland Eötvös University (ELTE) in 1998. As a PhD student of the ELTE Doctoral School he continued to work under the supervision of András Patkós. After obtaining the PhD degree in 2002, he worked as a young researcher in the MTA-ELTE Statistical Physics Research Group. In 2005 he obtained a 3 years OTKA (Hungarian Scientific Research Fund) Postdoctoral Fellowship. Since 2008, he is a member of the MTA-ELTE Statistical and Biological Physics Research Group. Between 2010 and 2011 he worked for a period of 14 month as a postdoctoral researcher at the Theoretical Physics Center, École Polytechnique (France).

His field of research is the resummation and renormalization of perturbative series in effective quantum field theoretical models and the investigation of finite temperature phase transition.

He is teaching jointly with Antal Jakovác the following courses: "Finite temperature and nonequilibrium field theory" and "Finite temperature quantum field theory with applications in astrophysics".
