Education
Ph.D. at the University
of Leipzig
Post-doctoral Research, University of California at Davis, funded
by a scholarship of the German Research Foundation
Research
•Expertise in the environmental trace analysis of organic
compounds using chromatographic and mass spectrometric techniques.
• Determine potential for the comprehensive characterization
of metabolites -metabolomics- in bio-fluids as a tool for diagnosing
disease including autism.
• Address fundamental questions regarding environmental factors
in autism and the search for tools to assist in the diagnosis of
autism.
• Development of analytical methods based on LC/MS and GC/MS
as tools for metabolomics.
• Quantitative profiling of urinary tryptophan metabolites
by on-line solid-phase extraction – liquid chromatography
– tandem mass spectrometry for the assessment of metabolic
dysfunctions associated with autism.
• Developing a sensitive technique for the analysis of vitamin
D metabolites as a tool in obesity research
• General analytical laboratory support and student mentor.
