Thrilled to share that I’m co-convening a session at AbSciCon26 in Madison WI focused on how self-assembly and self-organization drive chemistry toward the emergence of life! ✨

Happy to share some amazing news… 🎉

I successfully defended my PhD last month! It’s been a wonderful 17-year journey through four degrees across two very different fields. I’m grateful for everyone who helped along the way — and excited for what’s next.

Which brings me to update #2…
