Senior Lecturer, Pharmaceutical Sciences
Pharmaceutical, Chemical & Environmental Sciences
Dr Dionysius Douroumis obtained his Diploma in Chemistry and PhD from the Department of Pharmacy at Patras University in Greece. He studied the development of electroanalytical techniques for in situ monitoring of drug release from liposomal formulations. He worked as a postdoctorate fellow (2004) at the Friedrich–Schiller University of Jena, Department of Pharmacy, with Professor Alfred Fahr. He studied the development of parenteral formulations of antiepileptic drugs in a post funded by Novartis Pharma, Basel.
After the completion of this project Dr Douroumis worked as a team leader (2005) again with Professor Fahr in the development of nano-liposomal formulations and treatment of rheumatoid arthritis by applying photodynamic therapy in a post funded by Biolitec Pharma GmbH. Following this, he worked for Phoqus Pharmaceutical plc as a senior scientist (2005) at the product development department. His main tasks were the development of sustained/pulsatile release formulations, fast disintegrating dosage forms (FDDF) and taste masking of bitter drugs, also focusing on the development of coated coronary stents (Cypher) using a novel electrostatic dry powder deposition technology (EDPDT).
Dr Douroumis joined the School of Sciences at the University of Greenwich in November 2007, gaining a Postgraduate Certificate in Higher Education (PGCert), from the School of Education, University of Greenwich in 2008.
He is a member of the Journal of Nanomedicine and Nanoscience (JNMNT), Omics Publishing Group Editorial Board, and the following societies:
Pharmaceutical Product Development, Manufacture and Control
Drug Design and Delivery
Pharmaceutical Analysis and Testing, Mathematics and Statistics
Pharmaceutics and Formulation
