None of this would be possible without my incredible group, postdocs (Shweta Sharma and Sidong Tu), PhD students (Armin, Orhun Ayar, and Muzaffar Rafique)roup, and undergrads Alessandro, Ryan, Antonio, Caroline, Isaac, Ria, Enzo, and others — for their hard work and dedication.

I'm especially thrilled that this award is about more than research — it's equally about education, mentorship, and outreach. We'll be building immersive VR/AR tools that let K-12 teachers, high school students, and undergraduates explore suspension physics hands-on.

We're diving deep into the fundamentals of particle dynamics and rheology, with the goal of turning what's largely trial-and-error today into physics-based, predictive design rules. There are so many unknowns left to explore, and that's exactly what makes this work so exciting.

Particles suspended in fluids, from Newtonian solvents to complex polymer solutions, flow and behave. These suspensions are everywhere, in paints, foods, and countless everyday products, yet predicting how they'll behave during processing is still remarkably hard.

Network science insights into rheology of dense suspensions
Some dense particle suspensions exhibit unusual behavior; they flow like liquids at rest but become thick or even solid when stirred rapidly. This puzzling behavior, known as discontinuous shear thick...

To answer WHY? We dug into structural rigidity theory, and third-order loops have been hypothesized to be the smallest minimal rigid structure. As per Lamans’ theorem (1970s), triangles are the smallest isostatic structures that do not deform under externally applied load. Happy to chat!

FINAL REVEAL: Viscosity collapses beautifully when plotted against the number of 3rd-order loops. This collapse is universal — independent of stress, volume fraction, or even friction. We even find a power law behavior, signifying max. n3 at jamming.

Abhinendra Singh @asingh-case.bsky.social · 09/09/2025
This is where things got interesting: The mean-field golden standard models suggest viscosity to be driven by the frictional number of contacts. To test this, we performed extensive simulations changing packing fraction, stress, and sliding friction. Spoiler: NO collapse

Earlier work hinted that DST onset ≈ loop formation. Here, we visualized them directly. Sure enough, loops first appear right as suspensions undergo DST. We tracked how 3rd–8th order loops evolve with stress, packing fraction, and friction.

To answer the question: "What is the motif that underpins the DST transition?" Enters network science: We disentangled our frictional network into 1) isolated edges, 2) Connected edges, and 3) closed cycles, aka loops (3-8).

Abhinendra Singh @asingh-case.bsky.social · 09/09/2025
It is established that DST manifests itself as a stress-activated transition from an unconstrained to a constrained state, leading to the formation of the frictional contact network. Now the question we had was “How about the topology/motif of this network that underpins DST?”

Thrilled to share our latest work published in JCP by my (junior) undergrad and postdoc. The work was featured in "2024 JCP Emerging Investigators Special Collection." We uncover the network motif behind DST. A mini-bluorial below pubs.aip.org/aip/jcp/arti...

Yay! It's a hat-trick! Student papers in May, June, and July! In May, our first ML paper was led by Armin Aminimajd; in June, the paper was led by Alessandro d'Amico; and in July, 2nd paper by Armin. Detailed posts coming soon after submitting proposals :) Exciting times ahead :) #softmatter

This is massive, and we are excited to go beyond just the contact network. Our dream is to predict the flow of suspension based on a snapshot. Stay tuned for more updates! Feel free to reach out to us if you'd like to chat.

With lots of hard work (2 years), Armin came up with the brilliant framework of deepGNN, inspired by work from Rituparno Mandal, showing that if we know the initial condition (or particle position) and train the model on low viscosity states, we can predict FCN in high viscosity states.

Abhinendra Singh @asingh-case.bsky.social · 20/06/2025
My question to Armin was: Experiments capturing the network are hard (massive respect to experimentalists), simulations are nice (but cumbersome close to jamming). Can we use ML? Can we train a machine on faster simulations and predict conditions close to jamming?

Wondrous works by @lilianhsiao.bsky.social, by Safa Jamali, @emanueladelgado.bsky.social in dense suspensions, and by @karenedaniels.bsky.social in dry granular materials have shown that my crucial contact network is to predict the response of dense amorphous materials, which was our motivation
