Biography

Hello! I am an astronomer working as Lecturer at the School of Physics. I graduated from a BA in Physics with Astrophysics from Trinity College Dublin (Ireland), and later from my PhD at the Institute of Astronomy, University of Cambridge (UK). At that time, I was also fortunate to spend a year as a European Southern Observatory (ESO) student in Santiago (Chile), working on data from the Atacama Large Millimeter / submillimeter Array (ALMA) telescope. Finally, I was a Fellow at the Submillimeter Array (SMA) telescope project, part of the Center for Astrophysics | Harvard & Smithsonian in Cambridge (MA). There, I got to operate and use the SMA (situated on Mauna Kea, Hawai'i) for science and teaching.

Research Interests
