Abzer got a PhD now!
We are incredibly proud to share that Abzer, the first PhD student from our lab successfully defended her PhD thesis last Friday. Abzer’s PhD work was dedicated to developing computational metabolomics tools to better understand chemical exchange in microbial communities, with a particular focus on drug–microbiome interactions. Perfectly timed with her defense, we are excited to share that Abzer’s second thesis chapter is now available as a preprint on bioRxiv. The computatio

New Paper: High-Frequency Microfluidic Fractionation for Compound-Resolved Bioactivity-Based Metabolomics
We are super excited that our work on microfluidic-based LC-MS/MS fractionation, in combination with bioluminescence bioreporters for compound-resolved bioactivity metabolomics, was just published: https://pubs.acs.org/doi/10.1021/acs.analchem.5c04612 Making use of high-speed, low-volume fractionation, we can achieve similar sampling rates for bioactivity measurements as for the mass spec DDA cycles, which enables correlation of LC-MS and LC-bioactivity datapoints to identify
