Vietnamese and other peoples of Southeast Asia have naming conventions very much different from those in the Anglosphere. For us, writing our names overseas is a big headache. Let me first explain Vietnamese names, then I'll touch on names in other cultures.
It was great to see Dr. Katharine Hayhoe's talk on campus yesterday (@katharinehayhoe.com). She raised the message of hope, which is much needed in our time. Thank you.

As a tree ring scientist, I routinely fix dating problems, if you know what I mean.

It's so difficult to enter a different field. With today's rejection, I've tried 4 climate history and 4 archaeology proposals, all with excellent historians/archaeologists, but all unsuccessful. These discouraging experiences are telling me to stick to safe, single-field projects. But I'm stubborn.

Update: not funded. So the dream was bad omen :(
Last night I had a dream that my NSF proposal was funded. Then I woke up realizing it was a dream. But I grabbed my phone and logged in to research.gov to check anyway. And yep, still pending...
Maybe I'm thinking about this stuff way too much.

Last semester I taught a tree ring class, and I also partnered with the local forest preserve to do research & outreach. So putting 2 and 2 together, I took my class to a preserve site for field trip. It was a gorgeous fall day and we had so much fun! esec.illinois.edu/news/2025-12...

Geology can take many forms, from the study of rocks and minerals to the living records preserved in trees.

A student of mine asked our group to summarize #AGU25 in one word. For me it's HUGS. This year was tough for us scientists, and for some of us it was extremely tough. So it felt good to meet old friends and hugged it out.

If you will be at AGU next week check out the following presentations from my lab group and UNR Geography.
Thursday, Heather Haines will present PP43D-1233 Arid zone dendrochronology of the widespread and ecologically critical Mulga tree

Finally, we also contribute to Guleed Ali's talk on using subfossil wood to date the timing of ice sheet maximum for the Juan de Fuca lobe of the Cordilleran Ice Sheet. Definitely check out Guleed's poster too! eppro01.ativ.me/appinfo.php?...

On Wednesday afternoon, I will wrap up with a new method of handling BI data. We identify several issues with using delta BI to correct for the heartwood-sapwood color change, and propose using change point detection and color correction as the way forward. eppro01.ativ.me/appinfo.php?...

Update: I contacted Holger Gärtner, a wood anatomist, and was told this is likely aphid impacts. I'm gonna look for an entomologist on campus! linkinghub.elsevier.com/retrieve/pii...

Yeah our hypothesis is that it's a flood response since these trees are in a floodplain but I don't know the mechanism yet. It's not like they have traumatic resin ducts like conifers 🤔

Yes! We haven't dated the cores yet, just finished scanning. I'll let you know in a few weeks. This is an undergrad project looking at sliver maple in a floodplain.

Crowd sourcing from the Bluesky hive mind: what are these patches with what look like ducts inside that I'm seeing on silver maple? They don't occur in every ring, rather sporadically. @yellowbuckeye.bsky.social @l-tulipifera.bsky.social #dendro

I am teaching a course on ancient trees and tree rings at the NY Botanical Garden on Sunday, October 26th and Sunday, November 2nd.
We will learn about past environments, the amazing lives of trees, and what old trees tend to look like.
