Thank you! I'm also a big fan of your recent work!

@mela-doerr.bsky.social and other authors not on bluesky congrats! 🥳

Thanks to all authors for their efforts in getting this paper out there! We found integrins facilitated the specific uptake of symbionts in coral and Aiptasia larvae, shedding new light on the mechanisms of symbiosis establishment in cnidarians.

We're excited to share with everyone a preprint of our manuscript that resolves the cellular origins of the symbiosome in cnidarian-algal symbiosis through proteomics of the symbiosome, RNAi, and CRISPR/Cas9 experiments. ⬇️

Would love to attend but I'm busy traveling. Could you send a link anyways? my student seems also interested 😊

Stem cell-specific NF-κB is required for stem cell survival and epithelial regeneration upon intestinal damage Summary: Stem cell-intrinsic NF-κB activity is essential to prevent apoptosis and ensure proper intestinal epithelial repair following injury.

Last chapter of my PhD is out now! This project got me excited about the various roles of immune regulators like NF-kB. Drosophila taught me a lot about this concept, and I'm happy to apply my knowledge to Aiptasia. I will always treasure my time with the fly journals.biologists.com/bio/article/...

I'd love to be added!

📢#TMHMS25 is just around the corner! 🦠🌊

Join us to dive into the latest discoveries in #marinehostmicrobesymbioses and explore how microbial superpowers can contribute to restoring ocean health!

Theory of host-microbe symbioses: Challenges and opportunities Growing insight into microbial symbioses highlights the need to model these systems mathematically. We discuss three areas requiring theoretical advan…

Trainees and faculty that I had the privilege to be a part of did something quite special. The context here is that experimental and theoretical biologists were in a room together on Coconut Island, Hawaii for 3 weeks to hammer out a vision #holobiont theory. 🧵

Custom made microscope setup to live image samples from a 96 well plate

Spent the week in Cambridge with @benkinsjenkins.bsky.social testing this custom made microscope to live image Aiptasia larvae. Got some cool videos that we hope to share very soon! Thanks for hosting me Ben!

Coral spawning up close from my travels to Okinawa at this time last year. 😍 I learned a lot about coral fieldwork and gained valuable insights into immune mechanisms of symbiosis establishment, can't wait to go back! #SymbioSky

I've been busy the last couple years developing Aiptasia as a genetically tractable model organism to study corals. Here you can see me injecting CRISPR-Cas9 into these fragile little Aiptasia zygotes. Hopefully soon we will have our very first mutant lines!

Was a pleasure to present my work on immune regulation of symbiosis in corals and anemones at the Wild frontiers of model organisms conference hosted by @events.embl.org Highly recommend you checking out this event again in 2027! #EESWildModels

Cell cycle arrest in the cnidarian-dinoflagellate symbiosis.

Corals maintain stable populations of essential photosynthetic symbionts by controlling their cell cycle, not by eating them! Our new #PNAS paper monitored and modelled #aiptasia cell cycle, autophagy, and expulsion for over a year. #symbiosis #microbiology www.pnas.org/doi/10.1073/...

These parasite-like partners have lost photosynthesis but retained chlorophyll... are they friend or foe?

@currentbiology.bsky.social #protistsonsky #symbiosky #microsky #coralreefs

Fireworms (Hermodice carunculata) are a reservoir and potential vector for coral-infecting apicomplexans Corals (Cnidaria; Anthozoa) play critical roles as habitat-forming species with a wide range, from warm shallow-water tropical coral reefs to cold-water ecosystems [1-3]. They also represent a complex...

🚨New Preprint Alert: Are bearded fireworms🪱 acting as vectors for Corallicolids? Here we show evidence that H. carunculata is acting as a reservoir for these coral-infecting Apicomplexans, but corallicolid functional roles in the holobiont are still unknown! 🪸🦠.
