Abhinendra Singh @asingh-case.bsky.social · 07/07/2026I'm deeply grateful to my colleagues Joao Maia, Mike Hore, Sveta, Sam Root, Chris Wirth, and Kathleen Harper, among others, for their constructive and generous input, and to my friends beyond Case — Vivek Sharma, @samanvaya.bsky.social, @ankurg90.bsky.social and @meeraramaswamy.bsky.social 100
Abhinendra Singh @asingh-case.bsky.social · 07/07/2026None 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. 100
Abhinendra Singh @asingh-case.bsky.social · 07/07/2026I'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. 100
Abhinendra Singh @asingh-case.bsky.social · 07/07/2026We'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. 100
Abhinendra Singh @asingh-case.bsky.social · 07/07/2026Particles 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. 100
Abhinendra Singh @asingh-case.bsky.social · 07/07/2026I am incredibly honored to share that I've received the NSF CAREER Award! Thankful to NSF for their support and to the program managers & reviewers for their hard work.

Abhinendra Singh @asingh-case.bsky.social · 29/10/2025Excited to present “Shear-thickening in dense suspensions: Beyond mean-field models and steady-state response” at the @cornellupress.bsky.social Soft Matter Seminar Series. Honored to be listed among researchers I’ve long admired and learned so much from. #everythingflows #networksrcool 020
Abhinendra Singh @asingh-case.bsky.social · 14/09/2025We were also invited to prepare a summary for Kudos. Here’s our paper distilled into 2–3 more accessible paragraphs! It was featured in @aip-publishing.bsky.social Kudos showcase. Find it here www.growkudos.com/publications...growkudos.comNetwork science insights into rheology of dense suspensionsSome 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... 110
Abhinendra Singh @asingh-case.bsky.social · 09/09/2025To 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! 000
Abhinendra Singh @asingh-case.bsky.social · 09/09/2025FINAL 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. 110
Abhinendra Singh @asingh-case.bsky.social · 09/09/2025This 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 110
Abhinendra Singh @asingh-case.bsky.social · 09/09/2025Earlier 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. 100
Abhinendra Singh @asingh-case.bsky.social · 09/09/2025To 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). 100
Abhinendra Singh @asingh-case.bsky.social · 09/09/2025It 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?” 100
Abhinendra Singh @asingh-case.bsky.social · 09/09/2025Thrilled 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.

Abhinendra Singh @asingh-case.bsky.social · 20/06/2025Thanks so much, Ryan! Appreciate the shoutout! :) 100
Abhinendra Singh @asingh-case.bsky.social · 20/06/2025This 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. 110
Abhinendra Singh @asingh-case.bsky.social · 20/06/2025With 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. 110
Abhinendra Singh @asingh-case.bsky.social · 20/06/2025My 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? 110
Abhinendra Singh @asingh-case.bsky.social · 20/06/2025Wondrous 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 110
Abhinendra Singh @asingh-case.bsky.social · 20/06/2025Pumped for the first student work published and featured on the cover of @softmatter.rsc.org.
