I'm here in Auckland and excited to present on our lastest project at #ICRS2026! Using repeated coral population surveys and 8+ years of in situ temperature data, we find an unexpected trigger of catastrophic mortality in a heat-tolerant species. Check out my talk on Thursday at 2:45, room 505 🌊🧪🪸
An underwater view of a shallow Red Sea reef flat showing an abundant yellow branching coral, Stylophora pistillata. The presentation title appears in the top of the image: "No respite at night: record -high nighttime thermal stress drives mass mortality in a reef flat coral population adapted to extreme daytime temperatures"

Join our team as a KAUST global fellow! An amazing postdoctoral program for early career researchers. We study ocean-reef connections and their influence on reef function and persistence under climate change. Reach out to discuss opportunities! 🌊🧪 kgfp.kaust.edu.sa

My latest @newscientist.com cartoon
A cartoon titled ‘The Life of a Scientist’.

(The life is depicted as a set of steps, three up then three down with a character on each)

Baby: Such a mysterious world! 
Child: I must search for answers 
Young adult: Each answer leads me to more questions 
Middle age: ... At least I've got lots of questions 
Old age: Ok, I guess questions are my thing now 
From grave: Such a mysterious world!

Coral reefs around the world have been subjected to unprecedented heat stress since early 2023. A new report finds heat-related coral bleaching has damaged corals in more than 80 countries, making it the most extensive bleaching event ever recorded, with no clear end in sight.

What happens when an entomologist-turned-marine biologist skims the latest articles in Coral Reefs: I read this as "the impact of NEONICOTINOIDS on the geomorphology of the northern Great Barrier Reef" and thought surely there can be no connection 😅

Just in case you haven’t seen the most recent paper from our group, @reefwally.bsky.social investigated solar bias in commonly used temperature loggers. Long story short, the accuracy of your in situ measurements depends on your deployment method and you should always shade your loggers! 🧪🌊

The U.S. NWS is a truly world-class meteorological predictive service, perhaps singularly so. Its cost of operation is only ~$3-4/yr per taxpayer—equivalent to a single cup of coffee—and yields a truly remarkable return on investment (at least 10 to 1, and perhaps 100 to 1). 3/11

I started surveying the shallow reef flats in front of KAUST for my PhD in 2020. I was impressed that corals could live in such extreme conditions - the water hits 38ºC in the summer! However, heatwaves in '23 and '24 were too much even for these corals. Today's survey had nearly 100% mortality 😞 🌊🦑

About half of them are live and yellow, while the rest are dead from natural mortality over the years.A few bright white coral colonies in the reef flat that are undergoing bleaching in August 2024.The same reef flat after the bleaching event. Photo taken December 2024. All colonies are grey and dead.

Last week we spent a few days in the northern Red Sea to deploy more temperature logger arrays. It was cold (for those of us used to southern Red Sea temperatures 😅) but the reefs are beautiful! We'll swap out the loggers periodically to see how temperatures change across depths over the year 🦑🌊

Home for the next week! We're off to the Farasan Banks of the south-central Red Sea to repeat some coral reef surveys. We visited in early June to gather benthic data and deploy temperature loggers. This data will shed light on how the unique oceanography of this region influences reef communities 🌊
