Andreas Pseftogkas holds a Diploma in Rural and Surveying Engineering from the Faculty of Engineering of the Aristotle University of Thessaloniki (AUTH). During the final year of his five year bachelor studies he completed his diploma thesis entitled “Global water mass variations from a dedicated hydrological model and GRACE-derived satellite data”. After his graduation (2018), he was admitted to the two year Postgraduate Studies Program of Environmental Physics, AUTH. He graduated in October 2020 after completing and presenting his postgraduate diploma thesis with the title “Comparison of inferred S5P/TROPOMI NO2 surface concentrations with in-situ measurements over Central Europe” and was graded “Excellent” (10/10). He is currently a PhD student in the Laboratory of Atmospheric Physics of the Aristotle University of Thessaloniki and is working on his PhD thesis under the subject: “Development and application of advanced algorithms to study air quality using satellite observations and chemical transport models”. His research interests focus on the monitoring of air quality and the direct effects of air pollution in climate change as well as in the analysis and validation of satellite atmospheric observations through inter-comparison of satellite, ground-based measurements, and chemical transport models simulations.
