In this episode, Dr Simcoe spoke about his research involving spectroscopy to look back into the early universe and search for the first stars. He also spoke about another interest of his - designing and building astronomical telescopes and instruments - and how it first began when he was still in high school. Lastly, he gave us a sneak peek into the job of a director of a huge astrophysics department like MIT's Kavli institute and the work that goes in to managing it.
