Check out this great write up of our field campaign out on Seneca lake in the @nytimes.com ! With @erinhassett.bsky.social.

I'm looking for a driven PhD student to join us at @au.dk and to both generate new paleoclimate data in the lab and work on computational problems to understand climate relationships across timescales.

Get in touch if you'd like to hear more, and apply by Nov 1!

I'd be delighted to sponsor a NASA Postdoc Fellowship focused on #biosignatures, #astrobiology, or the Origin of Life here at Hopkins! 🚀

✨Paper #2 has just been published @weareagc.bsky.social ✨ And it is about hopanoids!! Thank you @climategordon.bsky.social for trusting a brand new journal with your research. AGC is 💎 open access: free to publish and free to read 🙌 Geochemists, come publish with us! journals.uu.se/AGC/article/...

New published article entitled:

"Hopanoid distributions differ in mineral soils and peat: a re-evaluation of hopane-based pH proxies" from Inglis et al.

You will find the full article here: doi.org/10.33063/agc...

New Science Advances paper on Plio-Pleistocene northern African hydroclimate! Tl;dr the wet summer monsoon = summer insolation & the dry winter monsoon = global ice volume

Paper here (www.science.org/doi/10.1126/...), Brown press release here (www.brown.edu/news/2025-06...)

Now published in @agu.org Geophysical Research Letters!

What happens to marine archaea when they’re hungry? And what does that mean for the TEX₈₆ paleothermometer?

Full paper here: doi.org/10.1029/2025...

Thanks to my coauthors and mentors for their support — and stay tuned, more is coming!

I am excited to share our latest work, out now in
@natcomms.nature.com.

We used eukaryotic biomarkers and 18S rRNA genes to examine the ephemeral meltwater ponds of the McMurdo Ice Shelf, revealing pond-to-pond diversity and a biomarker signal for life below the shelf!

Wonderful write-up by the amazing @fatimagulhusain.bsky.social on our recent PNAS paper:

eaps.mit.edu/news-impact/...

All credit to you for leading this cool work! It is always a delight to learn more and more about the GOE.

So, our study pushes that back by over 100 million years and adds to the growing body of evidence that the oxidation of the oceans and the atmosphere were at times decoupled, and likely played out in a tumultuous non-linear fashion after the onset of oxygenic photosynthesis. 6/7

Out online today in @pnas.org our paper:

"Aerobic nitrogen cycle 100 My before permanent atmospheric oxygenation"

With coauthors Gareth Izon, @chrisjunium.bsky.social , Shuhei Ono, and Roger Summons.

P.S. - The deadline to submit an abstract in consideration for an oral presentation during the GRS is April 21st, 2024!

Are you an early career organic geochemist with exciting new science to share? If so, apply to the 2024 GRS & GRC in #OrganicGeochemistry! We hope to offset conf. fees for EC researchers pending available funding. Links: bit.ly/oggrs24 & bit.ly/oggrc24.

📣 As part of my DFF-funded project, WARMEST, I'm hiring a biomarker-loving postdoc to join my group and examine terrestrial climate + environment of the western Sahel during the Eocene.

Applications are due Feb 15th - contact me with any questions!

RT plz :)
