Dr. Sotirios Kakabakos obtained his B.Sc. in Pharmacy from the University of Athens in 1980 and his Ph.D. in Pharmacy from the University of Patras in 1989. In 1990-91 he was granted with a research postdoc fellowship and worked in the Clinical Biochemistry Department of the Medical School, University of Toronto. In 1992 he joined the Institute of Radioisotopes & Radiodiagnostic Products (IRRP) as a postdoctoral researcher, and in 1995 he got an Assistant Researcher position at the same Institute. In 1998 he became Senior Researcher and since 2004 he holds the position of the Director of Research. He was a member of the Scientific Advisory Counsil of the IRRP and INRASTES (1999-2020) and vice director (2012-2019). His research interest focuses on the development and evaluation of advanced immunoassay technologies with emphasis on multi-analyte immunoassays and immunosensors (optical and electrochemical), novel solid supports for bioanalytical applications, surface patterning and nanostructuring methodologies for protein, DNA and cell arrays, novel labels to improve the analytical sensitivity of immunoassays and development of novel miniaturized diagnostic tools. He is/was responsible and/or participated in numerous National and EU funded projects related mainly to the development of sensors for simultaneous determination of clinical, environmental and food-safety related analytes based on optical biosensors, as well as on the development of materials and methods for micro/nano patterning of surfaces for bioanalytical applications with a budget for INRASTES exceeding 2 M€. He has supervised many PhD, MSc and Diploma students in collaboration with the Universities of Athens, Crete and Patras. He is author/co-author of 133 papers in peer-reviewed international journals, 39 papers in proceedings of international congresses, 6 book chapters and of more than 200 communications in national and international conferences. He also holds 21 national, international and European patents, among which 10 refer to novel biosensing platforms. He has organized and was member of the organizing committee of several national and international conferences, he is a member of the Editorial board of Biosensors (MDPI),  and is regular reviewer in journals including Biosensors & Bioelectronics, Sensors and Actuators B, Analytical Chemistry, Analytical & Bioanalytical Chemistry, Microelectronic engineering, Colloids & Interfaces B: Biointerfaces, , Journal of Hazardous Materials, Talanta, Scientific Reports, etc.
