Excited to share our latest work with Guanming Zhang and @stemartiniani.bsky.social in @natcomms.nature.com, where we uncover universal long-range structure in three distinct noisy particle systems spanning soft matter and machine learning. www.nature.com/articles/s41...

Emergent universal long-range structure in random-organizing systems - Nature Communications
Noise is usually associated with disorder, but it can also generate large-scale order. Here, the authors show that three distinct systems, spanning soft matter and stochastic optimization, self-organi...

New preprint! So, say you're studying some critical transition. How do you catch its universality? Pair correlations? Boring! We threw line segments at the system, looked at intersections with clusters, and uncovered static and dynamical universal behavior of MIPS! arxiv.org/abs/2511.09444

New paper just out, as an editor's suggestion in PRL! While looking for the ideal isotropic bandgap material, we actually discovered new structures. These structures lie at the border between order and disorder, and that's good for optics! More about their structure here, tinyurl.com/3aej53ht ⚛️🧪

If everyone does it, it must be right…right? Not quite. In “All That Structure Matches Does Not Glitter” #NeurIPS2025 we show CSP benchmarks miss polymorphs and datasets are duplicated. New deduped data, polymorph-aware splits, METRe & cRMSE. Harder tasks, better models! www.arxiv.org/abs/2509.12178

Do systems where the equations are known but cannot be solved in less than exponential time count? If so just take Schroedinger's equation for an interacting many-body system. Perfect description of the problem with no solution :)

Thank you NSF! With this award we'll attempt to answer the question of how many stable materials could possibly exist. More generally, we'll quantify the number of possible outputs of a generative model in ML, and its link to the regularity of the output as.nyu.edu/departments/...
