From stellar physics to production AI
Senior Data Scientist · AI R&D · Astrophysicist
I build data pipelines and models that turn complex, large-scale datasets into clear decisions, drawing on a PhD spent observing the stars with some of the world’s most advanced telescopes.

01 / What I do
From terabyte-scale telescope data to production models.
I’m a Senior Data Scientist at Optum, with a PhD in astrophysics from Queen’s University Belfast. My research centred on observing the Sun and other stars to better understand stellar dynamics, which meant designing and running analysis pipelines end to end on terabytes of telescope data.
I’ve led collaborative projects spanning multiple continents, worked in Agile software teams, and published peer-reviewed research. I’m also an experienced science communicator who has represented Ireland and won awards for public engagement.

02 / Selected work
A few places my work lives.
- Next Circuit The next track on the Formula 1 calendar, tilted into 3D on scroll with its elevation lifted out of the terrain. Then the turns, DRS zones and race history.
- The Sun, Interrupted A scroll-story of Ireland’s 12 August 2026 solar eclipse: the timing, the coverage, and the path of totality that ran across Iceland and Spain.
- Solar & sky dashboard Live solar flare activity, lunar phase, transit positions and observing conditions.
- PhD & publications Observational astrophysics, space-weather monitoring and peer-reviewed research.
- Public speaking Conference talks, festivals and public events. Award-winning science communication.
- Projects on GitHub Code and experiments from research and personal projects.
