Wood is a really neat sample, quick little test before something a little bit bigger.

I like gooooooooold. #MALDI

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

Cleaning the lab, found upgrade decals from 2016. Yes, I plopped them on the workhorse.

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.

RhizoMAP getting mildly out of control due to time points 😅

Happy to share this one, outlining our workflow developed through Human BioMolecular Atlas Program (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…

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…

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…

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

Well I bought a pricey taco...

Always nice to see a stable transient and sub-ppm errors during a run #TeamMassSpec
