This week, LEAP REU students Troy Stephens + Katherine Frields and LEAP Momentum Fellow Giorgia Nicolaou presented "AI Generation of Thermodynamic Histories From Ice Crystal Images" at the 2025 @columbiauniversity.bsky.social Pathways Program (CUPP) Research Symposium!

What are geoengineering and cloud seeding, and what are their implications for future climate mitigation strategies? @karadlamb.bsky.social—research scientist at @columbiauniversity.bsky.social studying aerosols, cloud physics, machine learning—explains: news.climate.columbia.edu/2025/07/17/g...

Kyleen Liao did stellar work with @karadlamb.bsky.social, Pierre Gentine, and me a while ago on simulating PM2.5 emissions from California wildfires using graph neural networks (GNNs). Her paper with cool new model validation results is out now: www.cambridge.org/core/journal...

☀️ APPLICATIONS ARE OPEN for our Summer'25 RESEARCH EXPERIENCE FOR UNDERGRADUATES (REU) PROGRAM ☀️ - For undergrads (rising Soph/Jr/Sr @ a U.S. institution) - May 26 - August 1 - 5 research projects based in NYC and/or Boulder, CO 📆 INFO + APPLY by 3/15/25: leap.columbia.edu/education-2/...

Thrilled to see Patrick Dicus (LEAP REU'24) present at #AMS2025 last week! His poster is a result of his LEAP Summer 2024 Research Experience for Undergraduates work conducted with project mentors @karadlamb.bsky.social + Joseph Ko. Way to go, Patrick - keep up the great work!

So proud of #REU24 alum Ashley Nguyen (Berkeley'27) + her LEAP research poster @ #AGU24! (Ice crystal mentors: Joseph Ko + @karadlamb.bsky.social ) And a #NOAA puppy, because why not? 🐶 #LEAPEducation #community #mentoring #NSF #CUSEAS @columbiaclimate.bsky.social @ucberkeleyofficial.bsky.social

I made a starter pack for those working in or adjacent to Machine Learning for Earth System Modeling! Apologies if I forgot anyone, and feel free to suggest people to add :) go.bsky.app/C5DQNCe

This is incredible-- cirrus clouds on Mars. 😶‍🌫️ science.nasa.gov/resource/per...
