🚨 POSTDOC OPENING 🚨 NIH-funded Bio-Fluid Mechanics Postdoc in my lab @univmiami.bsky.social Hofstenia miamia | cilia-driven flows | behavior & neuroscience Collab w/ Mansi Srivastava @harvard.edu 🕒 Start: Jan–Feb 2026 ⏳ 1 yr, renewable | Email me ASAP! #Postdoc #Biophysics #FluidDynamics

I am looking to hire a postdoc to work with me on fluid-structure interactions in complex and active fluids. Ideally the candidate will have a strong background in numerical/asymptotic analysis and fluid mechanics (complex fluids / LCs even better). www.mathjobs.org/jobs/list/26...

I am looking to hire PhD students to join our Multiphase & Multiscale Flow Lab in Mechanical Engineering @univofmaryland.bsky.social Background in ME, Physics, ChemE, Civil (or related), interest in fluid mechanics/soft matter, and hands-on lab work are key. Please help spread the word!

Looking forward to being @upenn.edu tomorrow for the 26th Mid-Atlantic Soft Matter Workshop. I’ll share some of our recent work on granular materials, with results from @ramsudhirsharma.bsky.social, @sreeramr.bsky.social and others in the group!

The Fudge Lab at Chapman University is recruiting a postdoc for an NSF-funded project on the biophysics of hagfish defensive slime deployment. Please repost! Apply here: tinyurl.com/4p937dn5

Thrilled that our article in @annualreviews.bsky.social of Fluid Mechanics is out! “Fluid Mechanics Challenges in Direct‑Ink‑Writing Additive Manufacturing” doi.org/10.1146/annu.... I am grateful to the two co-authors, @raytyler.bsky.social and Brett Compton. @univofmaryland.bsky.social

New @univofmaryland.bsky.social article about our NSF project on sediment flows with Eckart Meiburg @ucsbengineering.bsky.social me.umd.edu/news/story/s.... Thrilled to see the project featured and excited to get started.

Excited to share our new preprint on the discharge of granular materials from a silo. Led by @ramsudhirsharma.bsky.social , we went after a simple question: What is the flow rate through the opening? The answer turns out to be "simple" and quite general. See more here: arxiv.org/abs/2509.14415 [1/4]

The GRFP lives!! (due end of October) www.nsf.gov/funding/oppo...

Excited to share that our NSF PMP project with Eckart Meiburg has been funded! We’ll study cohesive immersed granular flows through experiments and simulations to improve predictions of sediment transport & slurry processing. @univofmaryland.bsky.social @ucsbengineering.bsky.social

Check out the @kitp-ucsb.bsky.social conference we're (Vashan Wright, Sujit Datta, Nathalie Vriend) organizing: www.kitp.ucsb.edu/activities/s... for THIS JANUARY 6-9! Geoscientists, physicists and engineers: are you intellectually adventurous and been wondering "is this all there is?" 🧪

Our new study from Joanne Steiner’s PhD work and with C. Morize, P. Gondret, and I. Delbende has just been published in Phys. Rev. Fluids! We study vortex rings generated when a disk moves toward or away from a wall. doi.org/10.1103/ynxr...

Excited to be an invited speaker in EP018: Geophysical Granular Flows & Sediment Transport at AGU 2025 (Dec 15–19)! I’ll be sharing our results on cohesive granular materials. Many thanks to the organizers! Abstract submissions open until July 30. agu.confex.com/agu/agu25/pr... @agu.org

We are grateful to receive funding from the ACS PRF to investigate how fibers and anisotropic particles reorient, bend, and sometimes clog in porous media. From microplastic transport to fiber-laden inks, we aim to uncover the physics behind their transport through experiments and modeling.

Congrats to all the new Fellows! It’s quite an impressive cohort

A new article with @sreeramr.bsky.social is out in JCIS! We study the dynamics of droplets of fiber suspensions impacting surfaces, a topic important for coating processes and additive manufacturing, among others doi.org/10.1016/j.jc... @univofmaryland.bsky.social @ucsbengineering.bsky.social

Engineer and photographer Harold Edgerton was born #OTD in 1903. He pioneered various forms of high-speed photography using specialized cameras, strobe lighting, and other techniques. You’ve probably seen many of the images he created! 🧪 ⚛️ 📸 Images: MIT; H. Edgerton

Had a great time at @upenn.edu last Tuesday giving a seminar. Great discussions and cool research all around! Thanks to everyone for the warm welcome. Looking forward to future interactions!

Our new study, led by Philippe Gondret and Cyprien Morize (FAST Laboratory), part of Wladimir Sarlin's PhD, has just been published in Journal of Fluid Mechanics. It explores how impulsive motions generate waves. doi.org/10.1017/jfm.... @univparissaclay.bsky.social @univofmaryland.bsky.social

Sand is far more fascinating up close! Each grain is unique, with its own signature of geological history and micro-shape sculpted by time and erosion. Yet, collectively, they can behave as a fluid! magnifiedsand.com has a lot of cool pictures from all around the world!

From a visit to the Renwick Gallery in DC a couple of weeks ago: a very cool art piece by Lauren Mabry showcasing coiling instabilities in viscous fluids. A beautiful intersection of art, fluid mechanics (and some rheology!). @sorheology.bsky.social @apsdsoft.bsky.social

The Gallery of Soft Matter 2025 @apsdsoft.bsky.social has some amazing entries this year. Check them out here: engage.aps.org/dsoft/galler.... Make sure to vote! Not sure about the deadline, but there’s a QR code at the DSOFT table with all the details.

Lineup from our group at the @APS Global Summit: We will be covering studies on fluids, grains, drops, and suspensions! More details below.

Excited to share our new paper in @pnas.org doi.org/10.1073/pnas...! Ice cubes often appear cloudy because, as water freezes, air bubbles get trapped and scatter light. But how does freezing rate affect the shape of the bubbles?

Sad news… A giant in fluid mechanics and particulate flows cse.umn.edu/cems/news/me...

Stickiness matters! From powder handling to geophysical flows, cohesion in granular material plays a crucial role. We review in Soft Matter @roysocchem.bsky.social experimental approaches to create and control inter-particle adhesion pubs.rsc.org/en/content/a...

Looking forward to present our work on transport of particles in porous media at the Traffic and Granular Flow conference today. Big thanks to @apahlavan.bsky.social for the stunning illustration from his paper: doi.org/10.69631/ipj... - great way to motivate studying transport in porous media!

Back in Lyon for the Traffic and Granular Flow Conference tgf2024.sciencesconf.org. Started the day with a run past ENS Lyon—always great to revisit, though it hits differently realizing I started studying there 18 years ago!

If you are at the @apsphysics.bsky.social DFD meeting in SLC come join this morning to hear about a sticky problem: the clogging of suspensions! I will be giving an invited talk at 11:05 am in Hall 3, trying to share the work done by our group in this topic over the past few years

Poster ironed for the DFD-Interact session tomorrow! I cannot recommend enough fabric posters : take no space folded in a luggage, quickly ironed (plus additional blanket on the plane if you need one 😊 - although not very warm!)

If you are into granular material, piles and how granular jets fall and impact on a surface, @ramsudhirsharma.bsky.social got you covered on Sunday morning!

Here is the lineup of talks from our group and collaborators for the @apsphysics.bsky.social DFD Meeting this year. More fluid dynamics, granular media, suspensions, and clogging coming!

I thought of a sneaky way to find my people on this thing. Self-identify and I will add you... See you at APS-DFD! go.bsky.app/8Njfprh

Our video entry for the 2024 Gallery of Fluid Motion @apsphysics.bsky.social is now online! Some variations on Harold “Doc” Edgerton’s drop impact experiments youtu.be/xIITzWnnwYI?...
