Ruth Angus is a postdoctoral researcher in the department of astronomy at Columbia University. She received a D.Phil from the University of Oxford where she worked with Professor Suzanne Aigrain on methods for dating stars. Before that, she completed a Masters in physics at the University of Southampton, UK.
Ruth is interested in extrasolar planets — planets outside our own Solar system. She uses her expertise in star-dating to measure the ages of thousands of stars and planets in the Milky Way. By doing this she hopes to reveal the processes behind the formation of these alien worlds and their distribution across the galaxy.
