Dr. Pieter C. Dorrestein: Mass Spectrometry and Metabolomics
Research Summary: Mass Spectrometry and Proteomics of Therapeutic Leads and Their Targets.
Our work aims to develop new mass spectrometry based methods to understand the chemistry of microbes, our microbiome and their ecological niche. In short, we develop tools that translate the chemical language between cells. This research requires the understanding of (microbial) genomics, proteomics, imaging mass spectrometry, genome mining, enzymology, small molecules structure elucidation, bioactivity screening, antibiotic resistance and an understanding of small molecule structure elucidation methods. The collaborative mass spectrometry innovation center that he directs is well equipped and now has twelve mass spectrometers, that are used in the studies to investigate capture cellular chatter (e.g. metabolic exchange), metabolomics, metabolism and to develop methods to characterize natural products. These tools are used to defining the spatial distribution of natural products in 2D, 3D and in some cases real-time. Areas of recent research directions are capturing mass spectrometry knowledge to understand the microbiome, non invasive drug metabolism monitoring, informatics of metabolomics, microbe-microbe, microbe-immune cells, microbe-host, stem cell-cancer cell interactions and diseased vs. non-disease model organisms and the development of strategies for mass spectrometry based genome mining and to detect and structurally characterize metabolites through crowd source annotation of molecular information on the Global Natural Products Social Molecular Networking at http://gnps.ucsd.edu through the NIH supported center for computational mass spectrometry that is co-developed with Nuno Bandeira.

Potential Collaborative Programs with the Pharmaceutical Industry: We collaborate with numerous industrial and other partners on understanding of metabolomics data, therapeutic discovery, target ID, informatics of metabolomics and understanding the microbiome. Consultant or collaborator to nearly a dozen biotechnology companies for the detection and analysis strategies of molecules in agricultural, medical, personal care and biotechnological sectors. These aspects of collaboration can be arranged through the collaborative mass spectrometry innovation center or through the center for microbiome innovation. In the next year the lab will roll out the rapid response precision microbiome program.
