Born in Athens, Greece, in 1983. Holds a Diploma of Physics (University of Athens, 2009), a M.Sc. degree in Environmental Physics (20011) and a Doctorate in Physics (2018) in the Physics dept. of the same university. His Ph.D. Thesis was in the field of Solar Measurements for aerosol  and  trace gases research titled “Aerosol, Trace Gases and Water Vapour optical properties study, using spectral measurements of solar irradiance”.  He has worked at Atmospheric Physics group of University of Athens, at APCG at National Observatory of Athens and at Physicalisch Meteorologisches Observatorium Davos, World Radiation Center at Davos, Switzerland. He is an expert on solar spectral measurements and developing tools and algorithms to retrieve atmospheric physical properties of aerosols and gases. He specializes in the installation, maintenance and operation of measuring equipment and the quality assurance procedures of the data. He has 12 accepted publications in peer reviewed scientific journals and 96 citations (25/03/2019, source google scholar) and 16 publications in conference proceedings.
