(Bio-)Analytical Chemistry

• Complex mixtures analysis with focus on biological matrices (e.g. blood plasma/serum, urine, fecal material, CSF, pancreatic fluid etc.) by NMR
spectroscopy
• Development of NMR methods for complex mixtures analysis
• Implementation of NMR spectroscopy in clinics: diseases diagnosis/prognosis (focusing on Gastrointestinal and cancer diseases/symptoms
fingerprint and biomarkers detection)
• Developments of computational and experimental methods for NMR based metabolomics
• AI (artificial inteligence) and ML (machine learning) algorithms application in -omics
• Development of bio-, chem-informatical tools for -omics (mostly metabolomics), regarding the statistical analysis, quantification of
metabolites as well as their identification in complex bio-fluids.
