Check out our Flatiron team @BPS2026!

How can we extract unbiased transition rates from ligand-unbinding Random Acceleration MD (RAMD) simulations? Our new paper lays out the theoretical framework behind RAMD. Take a look! doi.org/10.1063/5.03... @benoitroux.bsky.social @yiweiding.bsky.social & Alessia Ghidini #MD #drugdiscovery

#BPS2026 The T&C subgroup is hosting a fun event on Saturday evening, Feb 21st 🎉 Open bar for 2 hours + food! Tickets are selling fast, so sign up soon: www.biophysics.org/2026meeting/...

Go use cryojax ! It's awesome! I can't wait to see what people do with it.

I finally made my webpage, check it out: pilarcossio.org

Happy new year!!🎆 & checkout our new preprint exploring optimal transport for cryoEM parameter optimization:

…and it works on real cryo-EM data!

To avoid unphysical structures, we incorporate a physics-based prior:

We can escape local minima and robustly explore the conformational landscape encoded in cryo-EM images.

Cryo-electron microscopy ensemble optimization using individual particles and physical constraints Biomolecules are inherently dynamic, and understanding their conformational ensemble distributions is essential for understanding their dynamics and biological roles. Cryo-electron microscopy (cryo-EM...

Happy to share our cryoEM Ensemble Optimization method! 🎉It infers optimal structures and their weights directly from individual cryoEM images - no maps just physics! with David Sliva-Sánchez, @erikhthiede.bsky.social & Roy Lederman www.biorxiv.org/content/10.6...

Thanks to all who attended the #BPS2025 #cryoem symposium yesterday, and the happy hour last night!

We heard some superb science at the symposium and had some great discussions which were continued in the evening.

And congratulations to Dr. Elizabeth Wright, our inaugural Almeida Award winner!

Nice time catching up with folks from @foldingathome.org at #bps2025

We are hiring a Flatiron Research Fellow in the Structural Molecular Biophysics team! Experience with cryoEM and/or membrane protein simulations are a plus! Happy to chat in person with anyone at #bps2025 ! apply.interfolio.com/160227

So happy that you are visiting! See you soon!

Looking forward to great science and cool scientists at #BPS25 next week

And before that a stopover in NYC 🍎 to give a talk at the Flatiron Institute and meet @pilarcossio.bsky.social and colleagues

New metric for calling significant detections of proteins in cryoEM images with 2DTM. Driven by Kexin Zhang in @grigoriefflab.bsky.social in collaboration with @pilarcossio.bsky.social

1/ Thrilled to announce Dr. Elizabeth Wright as the inaugural winner of the June Almeida Award for #cryoem! 🎉Elizabeth’s pioneering work in both cryo-ET methods and structural virology made her a perfect fit for this award. Congrats, Elizabeth!

We’re so lucky to have you!
