Evolution/Ecology meets Genetics @ Columbia University. We use a variety of organisms (🪰🦋🐸🪲) and approaches (mol evo and pop gen, mol bio, experimental evo, genetic engineering) to better understand constraints on adaptation.

NYC, it’s time to take to the streets again.

We’re joining over 40 cosponsors to protest authoritarianism, and march for a planet where we place people over profit.

📅 Saturday, April 19
⏰ 12pm
📍 Bryant Park

We’ll see you in the streets.

1. For the past thirty years I've had the best job in the world.


I've had the opportunity to follow my curiosity; explore the workings of nature and society; mentor students and junior colleagues in the same process; and teach generations of students about it all.

The distribution of highly deleterious variants across human ancestry groups
A major focus of human genetics is to map severe disease mutations. Increasingly that goal is understood as requiring huge numbers of people to be sequenced from every broadly-defined genetic ancestry...

Although it feels bizarre to be posting about research with what has been going on in the US this week, I want to highlight new work from graduate student @nemovrobles.bsky.social whose first-first author paper on mitonuclear incompatibilities in swordtails just posted on bioRxiv. shorturl.at/gC71V
Admixture mapping reveals evidence for multiple mitonuclear incompatibilities in swordtail fish hybrids
How barriers to gene flow arise between closely related species is one of the oldest questions in evolutionary biology. Classic models in evolutionary biology predict that negative epistatic interacti...

"We describe a #mtDNA variant that confers protection against variety of pathogens in #Drosophila. This protection was at least partially caused by enhanced cell-mediated innate #immunity, including higher numbers of immune cells prior to and during infection."

A naturally occurring mitochondrial genome variant confers broad protection from infection in Drosophila
Author summary The strength of immune response and the disease symptoms vary among individuals even when exposed to the same pathogen. Much of this variation is due to the genes directly involved in a...

This year I always had my camera and a small photo box to hand when I was gardening. My children are always finding caterpillars outside, and I wanted to document that a bit this year. With the exception of the garden tiger moth (Arctia caja), they all came from my garden.

Want to perform HIGH EFFICIENCY Homology Directed Repair in Drosophila spp? Try Atalanta plasmids. About 10X higher efficiency than other methods!
Tag or delete genes, invert chromosome regions, make scarless site-specific modifications. All with easy cloning.
This paper is proudly bioRxiv only!

How do animals know when it’s their turn to communicate during a conversation?
In our latest preprint, we study the behavior and neurobiology of aggressive visual turn-taking of Siamese fighting (betta) fish to find out.
