I'm hiring postdocs @berkeleylab.lbl.gov to drive cutting-edge research involving MLIPs, high-throughput workflows, chemical reaction networks, generative models, and open-source software dev. Full position description + application here: forms.gle/zePBZDmciXez... #Chempostdoc #AI4Science

Come work with @emorychannano.bsky.social and me! #robotics #nanochemistry #machinelearning #UCNPs

Interested in learning more about our recently published OMol25 dataset and the advances that it's bringing to atomistic machine learning? Check out this talk that my boy @samblau.bsky.social gave as part of the "Modeling Talk Series". #CompChem ⚗️ 🧪 #SciML

I'm presenting OMol25 tomorrow 7/29 at 9 AM PST as part of a talk series at Google. Learn how we built the dataset + how MLIPs trained on OMol are revolutionizing comp chem! Meet: lnkd.in/g4AAWkcK YouTube Stream: lnkd.in/ggmtMtTR Join group: lnkd.in/g5ciuNuX

OMol25 was calculated with ORCA. I want to acknowledge the work of the ORCA team to improve the quality of the gradient + the robustness of SCF convergence for complicated systems as part of the OMol effort - it was much appreciated and critical to ensuring that we're releasing high quality data!

🚨 Just dropped: Open Molecules 2025 — a record-breaking dataset co-led by Berkeley Lab + Meta FAIR. 100M+ DFT snapshots. Built to train #AI for real-world chemistry 🧪. Could reshape discovery in batteries, drug discovery & much more! @cs.lbl.gov ⬇️

The Open Molecules 2025 dataset is out! With >100M gold-standard ωB97M-V/def2-TZVPD calcs of biomolecules, electrolytes, metal complexes, and small molecules, OMol is by far the largest, most diverse, and highest quality molecular DFT dataset for training MLIPs ever made 1/N

It was a pleasure to give an IIDAI seminar on nanoparticle ML for gradient-based heterostructure optimization (w/ @emorychannano.bsky.social ) and neural network path opt for finding reaction transition states on MLIPs (w/ @thglab.bsky.social) - find the talk here: www.youtube.com/watch?v=-4jB...

🧠 New postdoctoral researcher position at Princeton for those interested in data science and machine learning! Specify my group if you are interested in working together. Deadline is May 31. Details: puwebp.princeton.edu/AcadHire/app...

Final day to submit abstracts for ACS Fall 2025! Reminder that @ewcspottesmith.bsky.social , Brett Savoie (Notre Dame), and I are organizing a symposium on "Chemical Reaction Networks, Retrosynthesis, and Reaction Prediction". Will be a mix of invited and contributed talks - please submit! #CompChem

the @gpggrp.bsky.social is at the ACS Spring 2025! come check out the works of Daniil Boiko and Rob MacKnight at the "ML + AI in Organic Chemistry" Symposium (Hall B-1, Room 4) today! extreme scaling of experimental chemical reactions via MS and an OS for autonomous comp chem!

Looking forward to speaking at ACS on Sunday at 5:30! Come learn about "Popcornn" - a new method for double-ended transition state optimization atop machine learned interatomic potentials that is substantially better than NEB or GSM.

Fantastic new work from Aditi & co that shows how to leverage the expressivity + accuracy of massive pre-trained MLIPs to distill smaller, much faster models that are still extremely accurate to drive downstream simulations - no need to compromise on speed vs accuracy!

Applications closing in one week! If you’re interested in a prestigious postdoc at the intersection of AI/ML and nuclear nonproliferation, don’t hesitate to apply - come work with me on fascinating f-block chemistry and computational/ML methods! (Must be a US citizen)

@samblau.bsky.social, Brett Savoie (Notre Dame), and I are organizing a symposium for @amerchemsociety.bsky.social Fall 2025 called "Chemical Reaction Networks, Retrosynthesis, and Reaction Prediction" under @acscomp.bsky.social. #reactionnetwork #CRN #retrosynthesis 🧪 ⚗️ #CompChem

Inverse Design of Complex Nanoparticle Heterostructures via Deep Learning on Heterogeneous Graphs Authors: Eric Sivonxay, Lucas Attia, Evan Walter Clark Spotte-Smith, Benjamin Lengeling, Xiaojing Xia, Daniel Barter, Emory Chan, Samuel Blau DOI: 10.26434/chemrxiv-2024-1dw4q

Very proud of this work, going all the way from implementing the kMC in C++ to building datasets w/ high-throughput workflows to designing the novel graph representation to training the custom hetero-GNN w/ on-the-fly augmentation to inverse design of novel nanoparticles with GNN-based optimization!

Long-range machine learning potentials strike again! 🚀 We benchmarked the Latent Ewald Summation method on diverse systems—molecules, solutions, interfaces. Learning just from energy & forces, it delivers the most accurate potential energy surfaces, physical charges, dipoles, and quadrupoles!

This week, "RNMC: kinetic Monte Carlo implementations for complex reaction networks" was published in @joss-openjournals.bsky.social. Work on RNMC started back in 2021, when brilliant mathematician Daniel Barter suggested using stochastic methods to study #reactionnetworks. #CompChem #ChemSky 🧪 1/6

I've been slacking on research updates here! A few weeks ago, a preprint for "HEPOM: Using Graph Neural Networks for the accelerated predictions of Hydrolysis Free Energies in different pH conditions" dropped on @chemrxiv.bsky.social. 1/5

Another chance to join our group! We are recruiting a PhD student in digital ligand engineering for nanocatalysis. Reposts and spreading the word to interested people in your network appreciated! jobs.ethz.ch/job/view/JOP...

Example nanoparticle heterostructure optimization, driven by gradients of UV emission with respect to layer thicknesses and dopant concentrations from our hetero-GNN (not accessible from kMC) and sub-second inference (vs days from kMC) #F24MRS

Excited to speak at #F24MRS Thurs 1:30 - 1st talk of my career w/o any DFT connection - we design a hetero-GNN for learning core-shell nanoparticle properties, train on first ever large-scale NP kMC dataset, and use autodiff to optimize -> discover far OOD heterostructures with >6x enhanced emission

We are hiring (resharing appreciated)! Given recent successful grant applications (I got my SNSF Starting Grant 🚀), we are extending the LIAC team with multiple openings (PhD/postdoc) for 2025. Apply now (deadline: December 20th) by filling in this form: forms.fillout.com/t/eq5ADAw3kkus. #ChemSky
