Currently looking for a postdoctoral position and interested in this kind of research? 👀 Dr Hagen currently has an open position in his new Computational Integrative Biodiversity group at Goethe University Frankfurt, for more details see: www.uni-frankfurt.de/48794987/Zen...

Join my brilliant grad student Megan and me [representing @Hopkins_PaLEO] in the 'Ancient Biomolecules' symposium at SVP 2025 in Birmingham! Prospective grad students and postdocs looking for opportunities in Molecular Geo-, Astro-, Paleobiology, catch me after my talk!

If you are planning to attend GSA Connects 2025 by @geosociety.bsky.social next week, stop by the 'New Advances in Geobiology' session! I will be talking about the evolution of skeletons as revealed by fossil biomolecules and biosignatures 🔬🧪🧬! #paleontology #fossils #astrobiology

Prof. Jasmina Wiemann has been selected for a prestigious Packard fellowship. This the first recognition of a paleobiologist by the Foundation! That is 8 Packard Fellows in 6 years for Johns Hopkins University. Prof. Wiemann's website is the stuff of movies: www.jasminawiemann.com

I’m thrilled to be a part of the 2025 class of #PackardFellows and I look forward to all the exciting & actionable discoveries at the interface of evolutionary biology, ecology, the geosciences, and chemistry that this award enables! @jhuartssciences.bsky.social www.packard.org/2025fellows

We have a new paper out - spearheaded by the brilliant Madison Tripp and Kliti Grice at Curtin in Western Australia: Biomarkers preserve exceptionally well in diagenetic carbonates rather than phosphates. #paleontology #astrobiology #geochemistry Link: onlinelibrary.wiley.com/doi/10.1111/...

I am very much looking forward to join my brilliant colleagues of the Ancient Biomolecular Lab @amnh next week to talk about frontiers in ancient biomolecular research! We will also discuss the current momentum in the field and the remaining big, open questions!

SVP 2025 abstract decisions are out: I am very excited to share that I will talk about how machine-learning applied to modern and #fossil biomolecules transforms our understanding of the early evolution of the vertebrate (+ outgroup) biomineralization toolkit! [1/2]

Planning to attend SVP 2025? Don't miss Megan's talk on her new approach to integrating molecular #fossils preserved in the rock record and in genomes! As a 1st-year JHU PhD student in EPS, she just won the Steven Cohen Award for her creative spin on Paleobiology! @jhuartssciences.bsky.social

Imagine you could not only chemically characterize individual molecules, but also simultaneously visualize them - in their biological framework or at mineral surfaces ... my AFM UV|Vis|NIR-Raman spectroscopy lab is officially operational, and the first data exceeded expectations! #biosignatures

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

Raman main system installation: All bits and pieces are assembled! Time for our first samples - until we add the Atomic Force Microscopy-module for Plasmonic and co-localized AFM-Raman next week!

One of the biggest stories in science is quietly playing out in the world of abstract mathematics go.nature.com/4lBOSqR

Always delighted to talk about the importance of the #fossil record! Learn more about research on #biosignatures, #evolution, #dinosaurs, and #astrobiology at JHU: www.instagram.com/reel/DMQNtCJ...

What a week: ✅ Wrap up 2 fun papers ✅ Receive 3-D Printers ✅ Hire awesome postdocs ✅ Win new funding for the lab ✅ Rig 8 ft x 5 ft optical table Next: ⬜ Install AFM UV/Vis/NIR Raman [11 days to go!]

I am endlessly excited to welcome Mariana and Pjotr to Hopkins! Our entire team is thrilled to have you on board - let's push the limits of the fossil record! 🤩 #evolution #paleontology #fossils #biosignatures #astrobiology

I picked up the current Re-issue of 'Reimagining #Dinosaurs' in @ National Geographic - just in time for #JurassicWorldRebirth! Our research is still as exciting as it was 4 years ago, but my lab is now proudly based @jhuartssciences.bsky.social [with co-featured Fabbri, Balanoff, & Bever labs].

I am star-struck to discuss recent progress on biomolecule and #biosignature preservation alongside so many legendary scientists in this C&EN feature: From #dinosaurs to the tree of life! So proud of the contributions from my lab @jhuartssciences.bsky.social! Link: pubs.acs.org/doi/full/10....

Reposting this brilliant summary of the current state of knowledge on protein preservation in deep time by @matthewcollins.bsky.social - holistic assessments of decay and stabilization kinetics are the way to go! #FossilFriday #dinosaurs #biosignatures
