New paper out in @egu.eu's Climate of the Past together with economists (@mbennedsen.bsky.social @erichillebrand.bsky.social) to apply their rate prediction tools to the Cenozoic stack for detecting the timing and duration of breakpoints. Really fun. @au.dk cp.copernicus.org/articles/21/...

On my way back from @uio.no where I served (for the first time!) as a PhD opponent with new pal @sallieburrough.bsky.social. We dug deep into the work of @davidkwright.bsky.social's student (now) Dr. Aljasil Chirakkal on Central Asian Pleistocene paleo-environments. Learned a lot!

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! phd.nat.au.dk/for-applican...

We’ve just started the second week of our summer course ‘Climate Change: Cross-Disciplinary Challenges and Solutions’! We have experts from different fields visit each day to provide new perspectives on the climate crisis, and students work in groups on case studies from different sectors 🌍 @au.dk

Thrilled (and honored!) that Prof. Cat Beck from Hamilton College visited me at @au.dk during her sabbatical in Cologne. Cat and I have worked in Turkana, specifically on the HSPDP Lake Turkana drill core, for many years. It was great to catch up and talk about fun new things!

We’re in Azerbaijan for field work! I’m collecting biomarker samples from a beautiful sediment sequence in the Azykh cave, where hominins lived over hundreds of thousands of years (we think, lol 😝). Downright honored to be a part of this team in this stunning landscape.

Check out some nice coverage of my DFF-funded Sapere Aude project to start this October! @au.dk @aarhusuniint.bsky.social dff.dk/hvad-har-vi-...

Had a fun lil photo shoot in our Biomarker Lab at @au.dk!

Today my new seminar course Cenozoic Paleoclimate begins! We'll be traveling through time(scale) from the PETM to ENSO reading foundational and state-of-the-art papers. Students will lead discussions and develop a project proposal to fill a knowledge gap 💡 Ooo goodness, I'm excited. @au.dk

Two weeks left to apply to this very exciting (if I do so say myself) PhD position with Professor Mads Knudsen and me at @aarhusuni.bsky.social!
