Stoked to see that @DebashB and me became comic book characters in the new issue of @NASAAstrobio graphic novel! You will see a lot more familiar faces in this inspiring story about "How to become an Astrobiologist" issue 9 here: astrobiology.nasa.gov/resour…

This is Zach Cregger’s approach to first drafts as a screenwriter. It’s called “elfing”. He’s right. ✍🏼

Conference season is here, and I'll be at #ASMicrobe! Come check out my latest results on the honey bee queen microbiome. I'd also love to chat about other ongoing projects on social bee multi-kingdom microbiomes, potential collabs, and opportunities to join the Caesar Lab at OU!

Had an amazing time speaking at #PintOfScience in Blumenau about one of humanity’s biggest questions: Are we alone in the universe?
Together with @lelef123 (Sweden) and @LFelipeB (EUA), we hosted the first hybrid edition. 2 hours, no slides, just science and great interaction!

We found that proteomes across life maintain a consistent elemental signature! Check our preprint that is already out during #AbSciCon26

#PPOD: Adapted for Extremes 🏜️
This image features two distinct families: a collection of ALMA antennas and a trio of vicuñas, a camelid related to llamas and alpacas. Unlike in almost every other way, the subjects of this image are linked by their extremely hostile home environment, high in the Chilean Andes.
The Chajnantor plateau, site of the Atacama Large Millimetre/submillimetre Array (ALMA) shown here, is 5000 meters above sea level, making it one of the driest places on Earth. The aridity is ideal for ALMA observations, which search for cosmic signals from the cold Universe that are readily absorbed by moist air. But the low number of cloudy days, along with a thin atmosphere, produces harsh conditions, pushing the limits of both engineering and evolution.

ALT Photograph taken of a group of the radio telescope dishes of the ALMA telescope in the Chilean Atacama Desert. In front of the dishes are three deer-like animals called vicuña. The ground is reddish orange sand stretch back to the horizon, with a steep mountain to the right. The sky overhead is a misty blue.

🚀 New paper out!
Since my first year in Saudi Arabia (2021), I saw the huge potential of its extreme environments! This work helps put Saudi Arabia on the astrobiology map and outlines a roadmap for the future of astrobiology in the Middle East.

I am thrilled to share that this fall I’ll be joining the University of Oklahoma School of Biological Sciences as an Assistant Professor! The Caesar Lab will study the ecology and evolution of host-microbiome interactions in social bees (honey bees, stingless bees and more) 🦠🐝
