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. ⬇️ www.biorxiv.org/content/10.1... Read on below! 1/12 🧵

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/...

📢#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! Please share with fellow marine science and microbiology enthusiasts!

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. 🧵 www.sciencedirect.com/science/arti...

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

1/6 Call for session proposals 16th International Coral Reef Symposium, 19–24th July 2026, Auckland, Aotearoa New Zealand. Session proposal deadline: Sunday 15th June 2025. Details and submission link at www.icrs2026.nz/call-for-ses...

🚨 Just under two weeks left to submit your abstract for ESEB2025 - don’t miss the chance to be part of the Symposium on the Evolution of Symbiosis and Interactions in Microbial Eukaryotes 🦠🔬 📅 Abstract deadline: April 25, 2025 🔗 More: eseb2025.com/list-of-symposia #ESEB25 #Symbiosis #ProtistOnSky

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

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/...

It is happening again! Consider taking our course on the Molecular and Cell Biology of Symbiosis at @MBLScience. We extended the deadline for applications to Apr 14, 2025. www.mbl.edu/education/ad...

Course updates! ⚠️ Molecular and Cell Biology of Symbiosis is REOPENING applications (deadline March 31), and Visual Neuroscience is EXTENDING applications (deadline April 1). Flyers below ⤵️ Read more and apply here: bit.ly/4acDH2V #ScienceStartsHere

🚨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! 🪸🦠. www.biorxiv.org/content/10.1...

The final paper from my PhD is out! Give it a read if you're into immunity, stem cells and guts! Thanks to @edanfoley.bsky.social and the rest of the team 💪

During my PhD, I met so many colleagues who only read papers for journal clubs or when their PI demanded it. Reading the literature is a must for PhDs. It keeps you sharp, sparks ideas, builds critical thinking, and once it’s a habit, it’s even fun. Young scientists: READ!

🚨New Preprint Alert!🚨 Integrins are key receptors involved in the phagocytosis of symbionts in cnidarians. This sheds light on the mechanisms of symbiosis establishment in coral reefs. A thread... #coralreef #aiptasia #marinesymbiosis www.biorxiv.org/content/10.1...

Can’t wait to be back in Kiel and at @geomarkiel.bsky.social to discuss host-microbe symbioses! www.metaorganism-research.com/seminars-eve...

Be sure to check out the paper onlinelibrary.wiley.com/doi/10.1002/... for more info on the performance differences; and for the first time, an exploration of family-level differences in symbiont community composition!

Another 🚨 new paper alert! We found some of the first evidence of a microbially-mediated life history tradeoff in tropical corals driven by dominance of our fave bacterial symbiont, Endozoicomonas! Read more about it here: animalmicrobiome.biomedcentral.com/articles/10....

Happy Holidays from our festive Aiptasia anemones! I will never get bored of looking at these cuties under the microscope 🔬 #marinescience #aiptasia

Bobtail squid uses the #V-ATPase proton pump to acidify the microenvironment in its light organ, which promotes specificity for the recruitment of bacterial symbionts. Does this strategy apply to other #symbioses? www.nature.com/articles/s42...

Ecstatic to announce I have received a Marie Curie PostDoc Fellowship to work in the Guse Lab and understand how immunity regulates symbiosis in Aiptasia and corals. Excited for the work to come!

Officially been living in Munich for one year as of today! Been having a blast working on such an interesting model organism. Here's a pic of one of my CRISPR mutant Aiptasia polyps associated with symbionts (red) 😍 #aiptasia #mutant

Getting back in the groove of things with my anemone friends after a relaxing break. Here's an image I captured lately of a juvenile Aiptasia polyp "kissing" a larvae 😍

Please let me reintroduce myself!
