My group at UNH will be at the upcoming APS #DFD2025 meeting, presenting on a range of topics from water surface signatures of subsurface processes, to disease transmission in seagrass. Looking forward to connecting with the fluids community!

His analysis proposes a novel way of thinking about the physics in this important region of turbulent flows, with implications for entrainment dynamics, as well as design of experiments and reduced-order models.

This work comprises the 2nd chapter of Zeeshan Saeed's PhD dissertation at UNH!

On the physical dimension of the turbulent sublayer at the turbulent/non-turbulent interface The turbulent/non-turbulent interface (TNTI) is a thin fluid layer that separates rotational and irrotational flows, playing a critical role in the multi-scale process of entrainment. This work exa...

Congrats to Zeeshan on the publication of this paper in JoT! πŸŒ€ Zeeshan showed that the physical thickness of a portion of the turbulent/non-turbulent interface is well described by a combination of the Kolmogorov and Taylor scales.

nearly 11% of the NSF workforce was fired today.
this WILL slow scientific progress.
this is hurting families.

we need to educate folks about all the GOOD that the gov't can do! To help @500womensci.bsky.social has made social media cards for what #NSF funds in each state: bit.ly/NSF_bystate

Don't be afraid to make mistakes AND don't be afraid to ask for help! When I started 5 yrs ago, I often felt like everyone was busy and I didn't want to bother senior colleagues with questions. I could have saved so much time/energy if I just asked questions and admitted that I didn't know things.

Yeah, that's understandable. Probably very dependent on size/scale of the colleges and different dynamics if it's a new transition vs. long-standing setup.

I'm in the "College of Engineering & Physical Sciences" at UNH and I think it works really well. Fewer barriers between those of us in engineering departments and math/physics, which makes collaboration easier, easier for students to switch majors within the college, etc. I have no complaints!
