Excited to share our new #biorxivpreprint

We discovered that the fruit fly #drosophila erecta requires food odor to mate and arousal is further enhanced by social group motion.

Cross-species analysis of brain activity reveals a novel gate evolved from within a conserved circuit

Peter Skovorodnikov and I are excited to present FERAL: a new video-understanding toolkit that maps raw video directly to behavior, no pose estimation required.
It works across species, from lab to field, and even in collective systems. (🧵1/n)
FERAL: A Video-Understanding System for Direct Video-to-Behavior Mapping
Animal behavior unfolds continuously in time, yet quantitative analyses often require segmenting it into discrete, interpretable states. Although manual annotation can achieve this, it remains slow, s...

@rorycoleman.bsky.social and I wrote an opinion piece called

'From neurons to novelty: Circuit mechanisms shaping courtship evolution'

We argue that now is a great time for neuro-evo research

From neurons to novelty: Circuit mechanisms shaping courtship evolution
The vast diversity of animal behaviors has long inspired ethologists and neuroscientists, but circuit mechanisms driving this variation remain elusive…

How does life evolve to adapt to modern cities?

Out now in Science, my PhD work with @lindymcbr.bsky.social uncovers the ancient origin of the “London Underground mosquito” – one of the most iconic examples of urban adaptation.

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!

We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵

The behavior of the flies itself. On a food patch they are much more active when in groups and so we looked into the role visual motion might play. turns out it is an important aspect of their mating behavior

People thought I was bonkers studying courtship and mating in Drosophila erecta nearly 50 years ago. Sometimes you just have to wait.
Our new paper would not have been possible without a brilliant team! Huge thanks to Katie Keller, @rorycoleman.bsky.social, @noelleeghbali.bsky.social, Sarah Zylka, @neuroluci.bsky.social 🪰🧪✨

Especially grateful for guidance and inspiration by my mentor Vanessa Ruta

Your foundational work on this (and so many other) Drosophila species courtship has been an inspiration for us!
