Biographic Notes
Vardan Adibekyan completed his PhD in 2009 in Byurakan Astrophysical Observatory, Armenia. From 2009 to 2011 he lectured as an assistant professor at Yerevan State University, while at the same time working at Byurakan Astrophysical Observatory as a research associate. From 2011 to 2016, he was a FCT post-doc researcher at the Institute of Astrophysics and Space Sciences (IA). Currently Vardan is a researcher at IA (Investigador FCT).
During the PhD his scientific research was focused on the studies of extragalactic objects. After moving to IA, he smoothly changed his main scientific orientation to Galactic objects. His current main research interests include the study of the statistical properties of extrasolar planets and their host stars. He is interested in the use of high resolution stellar spectroscopy (optical and near-IR) for the determination of stellar atmospheric parameters and abundances in solar-type stars. He is also very interested on the studies of the kinematics and chemical properties of the stellar populations in our Galaxy.
Currently, Vardan counts more than 90 refereed publications in total, 20 of which as a first author. So far, his papers received more than 3000 citations. Vardan is currently involved in several international collaborations and consortia. He is a member of ESPRSSO's Science Team, a member of HIRES Science Advisory Team (Stars and stellar populations WG), coordinator of PSM WP 132400 (Scientific Validation of PIC) member of the PSM WP 122300 (Fundamental Stellar Parameters) of the PLATO 2.0 mission.
