Prof. Georges Michaud has been a Professeur Émérite at the Université de Montréal since 2005. He has worked in their physics department as a professor since 1969, after obtaining his PhD in astronomy from the California Institute of Technology. He is the recipient of the 2006 C.S. Beals Award from the Canadian Astronomical Society and has been a member of ... Read morethe Royal Society of Canada since 1992.

Dr. Georges Alecian is a CNRS Research Director Emeritus at CNRS-Observatoire de Paris (LUTH). His main fields of research are stellar physics, theory and modeling of transport processes of elements and atomic diffusion. He was director of Laboratory/Department (LAEC/DAEC, CNRS-Observatoire de Paris, Université Paris-Diderot) from 1996 to 2001, and he has been member of the CoRoT space mission scientific council since 1998.  Since 2012, he is foreign member of the National Academy of Sciences of the Republic of Armenia (NAS RA).
