Dr. Sotiris Evgenidis (Chemist, MSc, PhD) is a post-doctoral fellow in the Lab of Chemical and Environmental Technology of School of Chemistry, AUTH., Greece). His research interests include: a) Theoretical and experimental study of multiphase systems, b) Transport phenomena under varying gravity conditions (0-20 g), c) Wetting of solid surfaces, d) Application of electrical impedance measurements for the diagnosis of Decompression Sickness and Coronary Artery Disease. He is holder of 2 European patents, has published 25 publications in peer reviewed journals and participated at 50 international conferences. Additionally, Dr. S. Evgenidis has participated in 12 European research projects (10 of which funded by European Space Agency-ESA) and also in the organizing committee of 5 international conferences. Finally, he has been awarded by ESA and NASA for his research under non-terrestrial conditions (micro-gravity and hyper-gravity) and successful technology transfer from space to ground applications.
