Oscar Sage David O’Hara, born in 1999 in Oxfordshire, United Kingdom, is a physicist with a strong foundation in both experimental and theoretical research. He earned his B.A. in Physics from Trinity College Dublin in 2021. During his undergraduate years, he contributed as a part-time Research Assistant at The Dublin Institute for Advanced Studies (2019–2021). His work there focused on monitoring the Earth's ionosphere at very low frequencies and investigating the impacts of solar flares.
Currently, Mr. O’Hara is pursuing a Ph.D. at the Cavendish Laboratory, University of Cambridge. His research encompasses two main areas: the development of a high-sensitivity Rydberg atomic sensor and the simulation and analysis of potential systematics in the Square Kilometre Array, a next-generation radio astronomy observatory. This work bridges cutting-edge physics with applications in sensing and astronomy.
