Following up on my invited DFD talk last year, @jackwilliamb.bsky.social and I put together an overview of the "Propulsion and interaction of wave-propelled interfacial particles," now published at @prfluids.bsky.social !

Eli will be showing off some of latest Open Hardware in just over an hour! @oshwassociation.bsky.social

Really proud to be a part of this team!

38 accomplished scholars join Brown faculty as 2025-26 academic year begins Representing a wide variety of disciplines and backgrounds, the faculty members join the Brown community to guide student-centered learning and engage in high-impact research.

Excited to welcome six new engineering faculty, @leokoz8.bsky.social, Feng Lin, Mehdi Saligane, Isabella Stupois, Trisha Tian and Joy Zeng, to College Hill for the fall semester! 👏 www.brown.edu/news/2025-09...

Today is the last day of #AAPTSM25! A big THANK YOU to everyone who attended. Your attendance and participation are what made the meeting great. We hope you all enjoyed your time in Washington, DC, and we look forward to seeing you in Las Vegas, Nevada, at the 2026 AAPT Winter Meeting. #AAPTMeeting

Looking forward to sharing our approach and some of our open hardware projects at the @aapthq.bsky.social Summer Meeting in DC! @oshwassociation.bsky.social

New research uncovers surprising physics of ‘marine snow’ Engineering scholars at Brown University uncovered unexpected dynamics in how organic particulates sink in the ocean, a process that plays a key role in marine nutrient cycling.

Postdoctoral researcher @robert-hunt.bsky.social of @fluiddanamics.bsky.social, in collaboration with UNC-Chapel Hill, has found surprising new insights into how particles sink in stratified fluids like oceans, where the density of the fluid changes with depth. www.brown.edu/news/2025-06...

New study uncovers surprising physics of 'marine snow' The deep ocean can often look like a real-life snow globe. As organic particles from plant and animal matter on the surface sink downward, they combine with dust and other material to create "marine s...

⚒️🧪🌊 Marine Snow: "It basically means that smaller particles can sink faster than bigger ones... That's exactly the opposite of what you'd expect in a fluid that has uniform density"

New research uncovers surprising physics of ‘marine snow’ Engineering scholars at Brown University uncovered unexpected dynamics in how organic particulates sink in the ocean, a process that plays a key role in marine nutrient cycling.

Some coverage from Brown @brownengineering.bsky.social : www.brown.edu/news/2025-06...

By the same principle, for a fixed particle volume, spheres are the slowest to settle in this regime, having the minimum surface area.

In stratified fluids, small porous particles can settle faster than large ones. In linear stratification, the settling rate is set by the solute absorption rate. New predictions and experiments in our latest work out today in @pnas.org.

Looking forward to sharing our experience and getting feedback on our student-led for-credit Alternative Protein course, the first of its kind at Brown!

Introducing CyberDiver!

This new untethered robotic device is capable of actively controlling impact forces and splash dynamics during water entry.
