As a graduation present, I give my PhD students posters based on their research. I have a few examples shown here (Dr. Pa Chia Thao and Dr. Reilly Milburn). These are done by PhD student and artist Isabel Lopez Murillo: analopezmurillo.github.io 🧪🔭⭐🎨

One reason I vote early is that it usually stops the constant texting, letters, and door knocking I get reminding me to vote. This year, I got two postcards and three texts AFTER voting, thanking me for voting. Not helping…

I would like to see a new feature on arXiv that labels preprints that use AI upfront, since apparently TWO slop papers were successfully uploaded to the preprint server over the last two nights... arxiv.org/abs/2610.26056 🔭🌟🪐

Likely the most important thing I've ever written — if you're an academic and the AI mania unsettles you, here's my best shot at presenting some intellectual tools that might help you articulate why. arxiv.org/abs/2610.27251

Adding typos in my proposal so people don't think I wrote it with AI.

One of the enormous advances in astronomy since my grad school days has been in our understanding of gyrochronolgy. Look at this amazing figure and reflect on the rich physics it contains about stellar spin down!

The paper is sufficiently short that I don’t think a summary here is needed, but I’ll highlight that this is part of a larger effort to fill the gaps in the gyro (rotation-age) sequence to get better ages for field stars.

Do not do science. Instead, make a model of how science is done, put it in a likelihood function, and marginalize over it. 🔭🧪

A while back, Elisabeth Newton visited and commissioned Isabel to do some for her students as well. I attached a few below. These are for Drs. Aylin Garcia Soto, Keighley Rockcliffe and Rayna Rampalli. 🔭🧪⭐🎨

If you are interested: Isabel does not use LLMs/AI in her artwork and the final work is worth every penny (at least in my view). Her contact info is on her website. 🧪🔭⭐

I'll summarize this: Mamdani asked NYers to keep air conditioning at 78 degrees. A wave criticism hit online. A MSNBC broadcast pointed out the US Department of Energy recommends that 78 degree figure. Immediately after, the US Department of Energy deleted 6,000 web pages related to energy saving.
