Dr. Jeremy Rigney — Dublin, Ireland
Data science, grounded in scientific rigour.
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 Sun 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 — work that meant designing and running large-scale analysis pipelines end to end.
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.
