In July 2013, Dionysios Vroulias completed his bachelors degree in Chemistry with Honors (Grade: Excellent) at University of Patras. Following his service as a quality control chemist in the Hellenic Air Force, he pursued a masters degree in Catalysis, Pollution Control, and Clean Energy Production at the same university. His thesis was focused on nickel modified catalysts for the production of synthesis gas from bio-gas. In 2025, he completed a second major in Chemical Engineering with Honors (Grade: Excellent), enhancing his interdisciplinary expertise and deepening his understanding of chemical processes, reaction engineering, and materials science. Continuing his academic journey, he pursued a Ph.D. at FORTH/ICE-HT, where his research focused on ionic liquid and polymeric membrane materials for the separation and dehumidification of gases. He is currently working as a research associate at FORTH/ICE-HT, where his research is primarily focused on scaling up membrane-based technology and advancing the development of functional materials for gas separation and environmental applications. More recently, his research has expanded into energy applications, particularly the use of ionic liquids in supercapacitors and energy storage systems and he has also focused on sustainable materials, including nanocellulose composites and barrier coatings for food packaging applications. Currently, he is serving as an adjunct Lecturer at University of Patras.
