Dr. Georgios Theodoridis is Professor of Analytical Chemistry at the Department of Chemistry, Aristotle University of Thessaloniki, Greece. He studied Chemistry (1990) and received his PhD (1994) in separations sciences from the Aristotle University. He then worked as (post-doctorate) researcher in the Universities of Pardubice (CZ) and Leiden (NL), in AstraZeneca UK DMPK and as team leader at the Edmund Mach Foundation, Trento Italy. His research focuses on the application of LC-MS and GC-MS in metabolite profiling and bioanalysis with emphasis on analytical method validation, QC and biomarker discovery.

He leads the BIOMIC (Bioanalyis and Omics Interdisciplinary Laboratory) at the Innovation centre of the Aristotle University ( and the FoodOmicsGR_Research Infrastructure, that brings together 90 scientists from 20 research fields and eight Greek Universities to map the content of Greek foods (

He has co-authored ca. 190 peer reviewed articles and 20 book chapters that generated more than 10.000 citations (April 2021) and made more than 200 presentations in international meetings. He serves as Editor of J. Chromatography B, in the editorial board of Metabolites, Separations, Frontiers in Molecular Biosciences and in think tanks-scientific bodies (EURACHEM, mQACC and other bodies).

Bioanalysis – Biomarker Discovery

Development of LC-MS and GC-MS methodologies for metabolite profiling and bioanalysis with focus on life science and disease biomarker discovery.

Our group has long experience and more than 60 protocols of in method development in LC-MS, GC-MS, HPLC analysis) for quantitative analysis of exogenous  (pharmaceutical, pesticides, or other drugs) and endogenous substances  (organic acids, vitamins, steroids, lipids, aminoacids).

Metabolomics defined as the application of unbiased global, or holistic, analysis of biological samples (e.g. animal/human biofluids, tissue, cell extracts, plant/food), are increasingly applied to discover new biomarkers. We have more than 15 years’ experience in planning, organising and successfully executing biomarker discovery studies on conditions/disorders such as rheumatoid arthritis, osteoarthritis, obesity, metabolic syndrome, premature birth, physical activity and physical exercise, ageing.

Foodomics constitute a new approach in food science and nutrition that provides information about the food metabolome. As the knowledge increases, new relationships are discovered between analyte compositions and quality properties. Foodomics are widely applied to study food authenticity, traceability and safety. Foodomics can play major role in the investigation of adulteration, discriminating expected and unexpected metabolites in specific products Foodomics addresses omic-approaches toward the holistic definition of food by means of a comprehensive set of tools that capture the complexity of the food matter and translate it in nutritional views. Integrated analytical platforms are combined to support R&D and innovation in the agrifood sector.
