Why Matt O’Dowd is on this page

Heritage: Matt O’Dowd is an Australian-born astrophysicist now based in New York; the cited Wikipedia article does not document specific Irish ancestry. Heritage classification: Irish-diaspora-named on the strength of the surname; the Australian-Irish-Catholic cohort is a plausible context.

Matt O’Dowd is an Australian-born astrophysicist who is Associate Professor in the Physics and Astronomy Department at Lehman College of the City University of New York and Research Associate at the American Museum of Natural History. He is also the writer and host of *PBS Space Time*, the long-running PBS Digital Studios series on theoretical astrophysics, cosmology and modern physics — one of the most internationally watched serious science-communication channels of its kind.
