Over the last 15–20 years I’ve helped hundreds of researchers, students, labs, and agencies. The same questions kept coming up. The same mistakes. The same “aha!” moments.

So I built the courses I wished I had when starting out.

Why create two full stable isotope courses?

Because more and more people rely on isotopes — but very few get proper training in how to design studies, interpret data, or use tools like simmr or MixSIAR with confidence.

Over the 19 years Ireland has had a derogation from the nitrates directive we have backed ourselves in to a corner. Which now leaves us having productive and economically viable farms or cleaner rivers and lakes, but not both.

Nitrates derogation
Back in the early nineties all across the EU a rule was introduced to protect rivers and streams from agricultural run off. At the last count 7,000 out of 137,000 farms in Ireland had received a derog...

Thanks for a really informative and well run evening. As an aquatic ecologist who has recently moved to the area I would love to learn more and help out. Whats the best way to follow up and get in touch?

Ever wondered how to make your stable isotope data more reliable? 🤔
A lesson from Nate Silver’s election polls might help.

Happy #WorldEggDay! 🥚
A few curious students and a few cartons of eggs led to one of my favourite isotope stories — testing whether “free range” eggs really lived up to their label. Spoiler: the isotopes told the truth.

Delighted to be back teaching on The Survivor's Guide to Stable Isotope Ecology for 2026 - its always a highlight of the year. A fantastic week of isotopic learning in a truly magnificent location. www.exedramc.com/courses/surv...

Food webs are the blueprint of ecosystems.

Want to know what fuels migrating birds? Or how invasive species disrupt rivers and lakes? The answers are in the food web — and stable isotopes let us read it.

Really neat work James and great to hear that beavers are having, at worst, no negative impact on migrating fishes, while also creating so much new habitat!

Newgrange • The Boyne Valley • Meath

Hoping for clear skies for the #WinterSolstice dawn tomorrow morning.

The world could use a little more light.
Aerial view of Newgrange Passage Tomb in the Boyne Valley, early in the morning. A light mist and low cloud hangs over the monument and surrounding fields.
