This past semester, I taught a graduate class called LLMs for Science. If you'd like to learn more or maybe teach about (moderately) technical and societal aspects of using AI in research, perhaps you will find my teaching materials useful! Comments welcome!

📣 📣 📣 A reminder to consider applying for this postdoctoral position where you'll use math/stats/ML to reconstruct complex climate fields. Reach out with any questions. I will start reviewing applications next week! 🌊 🧪
📣 Job Alert! I am hiring a postdoc to work on the project "From sparse data to full spatio-temporal fields: surface ocean carbon and beyond". The goal is to use stats, ML, data, and models to improve our estimate of the ocean carbon sink.

A lovely day with NYC high-school teachers! I made a small ML x Climate Science activity (hopefully classroom-ready) that uses decision trees to reproduce Köppen-Geiger classes. Pen-and-paper exercise at the end of the slides, and some code/coding ideas in the repo.

I gave a talk on Interpretability tools for Scientific ML at the wonderful Astro/AI workshop organized by @astroai.bsky.social. Who doesn't love a flowchart? But I promise the full picture, while still very incomplete, has a bit more nuance, so find my slides here if you'd like!

This speech is triggering a Montale moment
Then one day through a door left ajar
in among the trees in a courtyard
we glimpse the yellow of lemons;
and the ice in our hearts melts,
and in our chests
fanfares blare
from their golden trumpets of sunlight.
(Eugenio Montale, I limoni)

In these very very bleak times my fuel is the amazing people I interact with every day. The passion and wit and brilliance that have often made me think that I have the best job in the world. I can choose to cherish moments of shared science and friendship, even as I brace for more impacts.

🔭🤖 First day of the semester for me! Teaching undergraduate Astro I - always a fun one - and graduate machine learning for scientists - I love it obvi but it's more challenging post-chatGPT. I now run it w/ 8 in-class mini-assignments but still finding my way. Good luck to all who start this week!

In the spirit of focusing on the positives we can control, today was a big milestone for me - I submitted a big follow-up proposal to my PIVOT fellowship. If I get it, I will be able to fund a climate data science lab and support ongoing and new collabs. Cross your fingers for me please 🙏🏼 🧪🌊
