Dark matter is one of the most beautiful and baffling problems in physics - the identity of 85% of the matter in the universe is still unknown. I will describe how we know dark matter exists, and our best ideas as to what it might be. I will explore how my work in fundamental physics and in comedy are linked in their creativity. I will discuss the role of creativity and narrative in STEM, from both a personal perspective and an academic one. Working in STEM is often portrayed as all-consuming, but I have found that the advantages of adding stand-up comedy to my career have significantly outweighed the disadvantages.
