Jay Tang and I are hosting the next installment of New England Complex Fluids workshop Brown University Friday 6/21. Please consider attending and presenting a soundbite! More info: complexfluids.org/necf/index.php Registration in advance is required (free).

Please submit your abstract or register before 8:00 a.m., Wednesday, June 19th. For the soundbites, all topics on active research are welcome, at any stage of maturity. This meeting is possible thanks to the generous support of Brown Engineering, Brown Physics, and APS DSOFT.

Congratulations to Dr. Andres Zambrano on successfully defending his PhD dissertation, 'On the Locomotion of Rigid and Flexible Helical Swimmers in Dilute Suspensions at Low Reynolds Number' Brown Engineering. He will be joining Pratt & Whitney as a Senior Research Engineer. Proud!

Time for some Arts and Fluids! Kudos to the organisers of #BIFD2024 in #Edinburgh.

Explore the mesmerizing world of #FluidDynamics with @fyfluiddynamicson on high-speed photography, like the “Milk-Drop Coronet.” Modern recreations by Brown University students from Roberto Zenit's lab, highlight the beauty of #droplet impacts. PhD Voice - Independently Run PostdocVoice

Wrapping up an amazing summer Brown Engineering with our UTRA and high school students! Excited to see all the great things they will achieve in their future endeavours.

Another day Brown Engineering where students compete to maximize drag on badminton shuttles launched from a large air gun. The real challenge? Taking down the reigning champ—me (course tee, cool sunglasses, you know the drill 😎).

We are all set for the #APSDFD2024! Check out our exciting talks on #bubbles, #drops, #turbulence and some (brain juice) #cerebrospinal flows. Madeline Federle Mithun Ravisankar Brown Engineering

Had a lot of fun teaching physics to some brilliant young minds SquashBusters. Who says professors can't handle teenagers? (Spoiler: they ask tougher questions than my grad students.) Brown Engineering

Excited to share this journal article, which is the PhD work of Andres Zambrano, a former member of our lab! Check it out!

We know that cuts to federal science agencies are creating hardships for our members. That’s why we’re offering no-cost membership renewal for current members impacted. It’s just one of our efforts to support the #physics community. Learn how you can get involved:

This week, Madeline Federle and I got to test our homogeneous isotropic turbulence chamber in microgravity at NASA's Glenn Research Center! During the drop, the experiment experiences 2.2 seconds of microgravity, allowing us to study multiphase flows in microgravity. Stay tuned for more🫧 Brown Engineering

I am very happy to share that our paper on ‘Gas bubble dynamics’ is finally published in Reviews of Modern Physics American Physical Society. It was a great pleasure to write it with my friend and long-time collaborator Dominique Legendre. Happy bubble-reading! doi.org/10.1103/RevMod…

A new paper, by Professor Roberto Zenit (Zenit Research Lab), has been published in the latest issue of American Physical Society Reviews of Modern Physics. Read more: journals.aps.org/rmp/abstract/1…

The 2025 ENGN 0350/1350 Art Fluids Exhibition Brown Engineering was a fantastic success! Fountains of light and chocolate, an engineered Eden, campus wind tunnels, and more! Proud of my students for their creativity and hard work! #ArtFluids

Unfortunately couldn't make it to ICMF in Toulouse this year, but proud to share that my student Madeline Federle presented her exciting work on bubble emulsions in microgravity Brown Engineering. Great to see the next generation pushing boundaries! 🚀🫧 #ICMF2025 #FluidDynamics

Just out in PNAS PNASNews: The physics behind squash’s most satisfying shot—the nick. When hit just right, the ball rolls out with no bounce, "no mercy". A beautiful blend of precision and mechanics. The work was led by Mithun Ravisankar Brown Engineering pnas.org/doi/10.1073/pn…

Using science to explain the everyday world, Brown researchers from Professor Roberto Zenit's lab used the physics of a special unreturnable shot in squash to further the science behind shock-dampening technologies of mechanical systems. brown.edu/news/2025-06-1…

Huge congrats to the newest PhD from our lab, Dr. Mithun Ravisankar, on defending his dissertation Brown Engineering: “Bubbly flows in non-Newtonian fluids and viscous Newtonian fluids.” He’s now a master of all things bubbly and sticky. Next stop: Postdoc at Universitetet i Oslo! 🎉 Proud of you!

Just out in Physical Review Letters! What floats up and breaks scaling laws on the way?🫧Bubble-induced turbulence gets a viscoelastic twist by Mithun Ravisankar Brown Engineering Check this out: doi.org/10.1103/q7xk-1…
