About Me

My name is Owen. I am an Irish astrophysicist, currently enrolled as a PhD researcher at Trinity College Dublin , jointly supported by UC Berkeley under the supervision of Prof. Evan Keane and Dr. Vishal Gajjar . My research is based on transient astronomical objects using everything from pulsars as gravitational probes to searching large data sets for signs of ET.

I completed my undergraduate degree in Physics with Astronomy and Space Science at University College Dublin (UCD) in 2022. During this time I worked as a research assistant at UC Berkeley. Working primarily using LOw Frequency ARrays (LOFAR) looking for technosignatures on targets found by NASA's Transiting Exoplanet Survey Satellite (TESS).

When I am not looking at the transient sky, I like to cycle long distances to take pictures of the stars, go in search of the world with my dad on a GS 1200 and climb rocks for fun. I am also an avid MotoGP and NBA fan. Interested in talking about any of my research or other interests, don't hesitate to reach out!
