Brief return to the app formerly known as twitter to say that I'm defending my PhD in two weeks. If you're interested in tuning in, DM me for the link!

Little late on this one, but we had another paper out recently. In this perspective piece, we highlight a non-dimensional number specific to flapping flight that describes performance tradeoffs that come about from resonance in insects. We call it the Weis-Fogh number (N) (1/n)

suggesting that there might be a 'goldilocks' range of N that balances constraints related to energy use and maneuverability. Check out the perspectives piece here: academic.oup.com/icb/advanceā€¦ (3/4)

The Weis-Fogh Number Describes Resonant Performance Tradeoffs in Flapping Insects

Synopsis. Dimensionless numbers have long been used in comparative biomechanics to quantify competing scaling relationships and connect morphology to anima

other interesting results related to wing shape evolution, elastic energy storage in flapping systems, and what it means for a resonator to be 'efficient'. Check out the paper (open access) here: royalsocietypublishing.org/dā€¦ (10/n).

Moth resonant mechanics are tuned to wingbeat frequency and energetic demands

Abstract. An insectā€™s wingbeat frequency is a critical determinant of its flight performance and varies by multiple orders of magnitude across Insecta. Des

Thanks to my coauthors (not all on Twitter), @braiello, @SimonSponberg, @ngravish, @springsNwings, @usama_bsikandar, and undergraduate mentee Manon Harris who collected a good bit of the new data. More insect flight muscle physiology and biomechanics coming soon!

Sharing my new working paper on age and suicide impulsivity: Understanding age-specific suicide patterns can help tailor effective mental health interventions, and I'm proud this work can shed some light on this important issue.

Purchase-delay laws reduce firearm suicide for the overall adult population, but the effect is largely driven by a 6.1 percent reduction for young adults ages 21ā€“34, from John J. Donohue, Samuel V. Cai, and Arjun Ravi nber.org/papers/w31917
