My name is Lachlan Marnoch, and I have just begun a PhD - the degree of a Doctor of Philosophy, an antiquated title from back when philosophy was anything that involved deep thinking about any topic. The specific flavour of thinking which I’ll be doing is on astrophysics. What that means is that I will use physics to try and make sense of information from the night sky. As with my Masters, I’ll be studying fast radio bursts - very brief, very mysterious bursts of radio waves originating from other galaxies. They’re pretty fascinating, and I’ll get to explaining more about them soon.
