I create extensive exposomics and stable isotope resolved metabolomics workflows to link environmental exposures with health outcomes. Current focus: Phase II metabolomics

Starting my #ASMS2025 adventure with Waters users meeting. The TQ Absolute XR is definitely a highlight (we have the Absolute and we like it a lot; an increase in robustness is definitely a welcome feature).
Decent talks. Getting almost too technical at times but I've learned a lot.

#ASMS2025 is just around the corner. This year we will have two presentations (poster and oral) discussing our approach to #LC-MS profiling and analysis of Phase II metabolites in the urine. #teammassspec

Our latest manuscript describes an #LCMS platform profiling Phase II metabolites. We annotated 424 mercapturates, glucuronides, sulfates linked to over 200 environmental chemicals. This demonstrates ILGA's value for advancing #Exposomics

Our paper describing a dilute-and-shoot targeted LC-MS/MS method for measuring 35 urinary metabolites of #VOCs
and #tobacco alkaloids is now published in Journal of Chromatography B. The article is available here: www.sciencedirect.com/science/arti...

Here's a preprint of our manuscript papers.ssrn.com/sol3/papers.... a result of ~2 yr of work on #LC-MS ILGA workflow for comprehensive Phase II #metabolomics analysis. We highlight ILGA's use in #exposomics and elucidate impact of #environmental exposures on health.

This manuscript just came out in JBC
I'm glad we got to collaborate with Dr Wysoczynski and Tyler Jobe from his lab. Together with De Silva we provided stable isotope resolved #metabolomics data used in the manuscript.
