I study how environments shape behaviors and brains. Neuroethology, evolution, thermal biology, reptiles. Currently a Postdoc @mpibrain.bsky.social‬; PhD from @harvardmcb.bsky.social‬. he/him

As a longtime fan of cool papers in @currentbiology.bsky.social, I am really thrilled to see this out! This study sets the stage for understanding the origins of novel (vocal) behaviors. Big shout out to the main architects of this work @xmikezheng20.bsky.social and @cliffscience.bsky.social

Great @currentbiology.bsky.social study by @xmikezheng20.bsky.social @cliffscience.bsky.social @arkarupbanerjee.bsky.social 🧪🧠🐭🎶 Vocal repertoire expansion in singing mice by co-opting a conserved midbrain circuit node www.cell.com/current-biol...

🧠🌟🐭 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🧵

How do animals decide if they should forage for food or stay home to take care of newborn offspring? Whose needs come first? For my PhD work now out in Nature, we examined how hunger and parenting neurons interact and are reshaped postpartum in mice 🧵⬇️ www.nature.com/articles/s41...

A hypothalamic circuit that modulates feeding and parenting behaviours - Nature

Single-cell transcriptomic analysis of mouse hypothalamus and behavioural experiments show that specific hypothalamic networks regulate conflicting feeding versus parenting behaviours of female mice.

A nice, layperson writeup of my latest work, which is now out on eLife! TLDR: Using snRNA-seq, we find cell type abundance differences and sex-biased gene expression differences that may explain innate differences in mating + parenting behavior elifesciences.org/digests/1031...

The parenting styles of deer mice

Single-nuclei RNA-sequencing sheds new light on how two closely related species of deer behave differently when mating and caring for young.
