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.

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!

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].
