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…

Here is our new paper that we're really excited about. What makes a cell different from a rock? The answer we argue is the USE of information. But information carries meaning and that changes everything if we want to understand the "physics of life".

The origins of life session during #FALCON2025 featured an amazing keynote talk by our very own @silkeasche.bsky.social, intriguing roundtable discussions about the very definition of life and how to detect it, and, of course, many exciting contributed talks! Thanks to all the speakers! 👏
