Ecosystems Research

David Skelton

My research is directed primarily toward developing, optimizing, and applying mass spectrometry techniques using GC-MS and UPLC-MSn/MS for metabolomic and lipidomic profiling  of tissues and biofluids of ecologically relevant organisms exposed to chemical contaminants . We are using these techniques to inform exposure assessments, discover novel biomarkers of exposure, as well as monitor and understand the effect the exposure event has on organisms.   As part of this research I am developing and utilizing chemometric techniques to integrate transcriptomic, metabolomic, and lipidomic data to identify and quantify changes in metabolic pathways perturbed by the exposure event(s).
