Research Interests
My research focuses on the analysis and quantification of B vitamins and coenzyme A thioesters in seawater, as well as their intracellular and extracellular concentrations in bacterial cell cultures. After extracting the samples using various techniques in the laboratory, the analytes are separated by high-performance liquid chromatography (HPLC), and various mass spectrometric methods, such as Selected Reaction Monitoring (SRM) or High-Resolution Full Scan (HRMS), are used for analysis. Through this process, I aim to draw conclusions about the origin and fate of these analytes.
