  • Ludmila Alexandrova, PhD, Qualitative & Quantitative MS, PK, Metabolite ID, Metabolomics

    Ludmila Alexandrova started her scientific career in the United States with Syntex which later became Roche. During her career with Roche, Ludmila became proficient in bioanalysis, metabolism and pharmacokinetics (PK) of small molecules. She developed and validated numerous LC/MS methods for quantification of small molecules as well as metabolites to support PK, toxicology and clinical studies. She became proficient in metabolite identification (ID). In addition, Ludmila became a core member of several inter-disciplinary project teams leading product development. In recent years at Stanford, Ludmila focus has been on providing expertise and top-quality mass spectrometry support for scientific research by educating and collaborating with researchers, carrying out data analysis, and developing new mass spectrometry based analytical methodology.
