@Biographic Notes
Ivan Rybak is a researcher at IA. He was awarded a first degree in PHYSICS (specialization theoretical physics) by the Belarusian State University in 2012, a Master degree in Physics by the Graduate School of the National Academy of Sciences of Belarus in 2013 and a PhD by the University of Porto in 2018.
In 2012-2014 he was working as a research assistant at B.I.Stepanov Institute of Physics of National Academy of Sciences of Belarus in Laboratory of Theoretical Physics.He is a member of IA since 2014.
Current research interests focus on cosmology of early Universe and high energy phenomena. In particular, description of cosmic string network evolution and prediction the corresponding gravitational signals.Lastest publications at IAC. J. A. P. Martins, Patrick Peter, I. Yu. Rybak, E. P.
