President Lula and I are focused on increasing trade and deepening our strong partnership between Canada and Brazil.
We’re intensifying free trade negotiations with Mercosur — a bloc of South American nations with a GDP of over $4 trillion, and a massive new export market for Canadian businesses.

So relieved that my HR now employs “Millie, an AI campus concierge designed to assist with general questions and campus guidance”. We were all CLAMORING for that!

Incredibly impressed with my Senior student thesis papers, esp. considering the theme I assigned-evolution-wasn't previously an interest of any of these students. Bu by god reading and commenting on nine 7,000-word review papers at the same time as all the other end of semester sh*t may kill me yet

It was great to host another Brazilian-New Yorker evolutionary biologist—and total #bosslady —Ana Carnaval to speak to our first-year biology students at Barnard today!!!

Snow is fun, what’s less fun is that my landlord hasn’t turned on my heat yet. Thankfully the walls in this 1903-built (!) building are super thick so it’s losing heat pretty slowly, but 🤬🤬🤬🤬

I’m looking for a medical artist. I was awarded a grant to write a new lab manual and will need anatomical images created. Open to someone starting out!

Does anyone have recommendations for cellular GPS tags (GPS + GSM) for box turtles? I want to be able to have the data sent to me remotely via a cellular network. Needs to weigh 20-30g or less. These would be attached to box turtle shells with epoxy.

Happy to see this out in early view in Evolution! We tested the roles of signaling and camouflage in the evolution of iris color in Tyranni songbirds. Our findings suggest that bright irises are social/sexual signals mostly associated with species less vulnerable to predation

Accidentaly found a subreddit called "male living spaces". Just literally what the names says. Dudes posting photos of their living spaces to be rated or receive suggestions. I'm set for the next 8 hours.
