WOOHOO! 2024 is wrapped, and put into a collage. While two papers are accepted (not in press), there's a lot of things in review, and much more cool TEAM science is coming. It's been an interesting year, with some shifted priorities.. but here's to a bright (and healthy) 2025!
This turned out super cool, radiata pine resin pocket and canals.. just a quick look and I see several thousand species here, definitely more complex than SRFA excited to dig a bit more into this data. Wasnt expecting this, but glad 7T-DESI has 1.1M RP at mz 250 #TeamMassSpec
Always nice to see a stable transient and sub-ppm errors during a run #TeamMassSpec
We are saddened to share news of Alan Marshall’s passing. He was ASMS President (2004–2006), co-inventor of FT-ICR MS, 1999 Distinguished Contribution Awardee, and an ASMS Fellow (2025). Our thoughts are with his family, friends, colleagues, and mentees. loom.ly/q0KZfqM

If #TeamMassSpec is still here, I've posted some new tutorials for computational MS at my git repo github.com/PayneLab/Prote…
Super happy to share our new review in Nature Reviews Nephrology: nature.com/articles/s4158… @KPMProject @imaging_ms @IMSSNews @UTHSAResearch @PNNLab
If you (or anyone you know) is interested in high-field NMR and FTICR, there is an active ad out for a postdoc for studying natural organic matter! Check it out below: @Chemjobber #chempostdoc #NMRchat #TeamMassSpec careers.pnnl.gov/jobs/10522?lan…
It's nice to see another workflow for LCM top-down proteomics and MALDI, it's something that we've been focusing on since before I came to PNNL, neat to see it applied to a new disease state. doi.org/10.1002/advs.2…
Happy to share this one, outlining our workflow developed through @_hubmap to look into proteoforms in human kidney. We found logical insight into FTU level proteoform differences in healthy samples. Moving forward, diseased tissues hold a lot of secrets! doi.org/10.1186/s12014…
RhizoMAP getting mildly out of control due to time points 😅
Electrical you didn't beat me today... could've been a sparky in a different life. The plumbing is the *shitty* part. Pun intended... toilet flange this week.
Cleaning the lab, found upgrade decals from 2016. Yes, I plopped them on the workhorse.
Submit a letter of intent to one of @EMSLscience's open calls for proposals: bit.ly/4gN2lJk Open calls include Large-Scale Research, FICUS EMSL-ARM, and the Molecular Observation Network.
Single tissue untargeted multiomics? Yes, please! our new paper is now online. Untargeted Spatial Metabolomics and Spatial Proteomics on the Same Tissue Section @PNNLab @EMSLscience @IMSSNews @gormanbritt9 @bindesh1 @WatersCorp pubs.acs.org/doi/10.1021/ac…
Interested in spatial biology #TeamMassSpec? Experienced in #glycotime? Check out this add my colleague Dušan posted for a postdoc here at PNNL. A really amazing opportunity to work with a great team, please share! @Chemjobber #chempostdoc careers.pnnl.gov/jobs/10140?lan…
Wood is a really neat sample, quick little test before something a little bit bigger.
