Roman Cycle 1 CfP closed with a stellar response! 🚀 We received 374 proposals, including 309 for data analysis, theory & lab astrophysics. 65 proposals requested new observations totaling 14,386 hrs of telescope time, a ~12:1 over-subscription rate by hours. 🔗 Get all the stats: bit.ly/4sEoWO5

I'm excited to announce my newest paper out on arxiv: Expanding the High-z Supernova Frontier with JWST 🚀 We just used JWST to push transient astronomy to z ~ 5, discovering 68 supernovae...all without a dedicated time-domain survey. Here’s what we found 👇🧵 1/n

It's been an exciting 2025. I haven't done a great job promoting my work on social media, so over the next couple weeks, I'll make an attempt to summarize three of my biggest papers. Stay tuned...we'll see if I actually get this done.

As I have the past 3 years, I am organizing the a “Foodie Dinner” on Wednesday night, January 7th at 7pm. Location will be sent to those who sign up. At the current time, I have 3 spots left. PM if interested. #AAS247

🚀The Roman Cycle 1 Call for Proposals is OPEN! Unlock new discoveries with the Wide Field Instrument—your science starts here! Apply for funding to analyze Roman data, perform theory/lab research, and propose new observations. 🔭☄️ 📅 Deadline: Mar 17, 2026 (5 PM PDT) 📝 bit.ly/4q3jbbL

I don't post a lot, but I am particularly proud of this paper. It's the first observational sample of binary companions to stripped envelope supernovae. And places constraints on the binary evolution physics. It only took me 10 years to build with HST! arxiv.org/abs/2508.12677

In these turbulent times for science, I can't resist putting out my "Case For Space". It's sometimes a little scary to speak up, but here I go. I hope this doesn't go viral. 😉
