There is an old piece of wisdom in condensed matter physics that new materials should always be subjected to measurements at low temperatures. Improvements in high pressure technology have lead an increasing number of researchers to apply this old wisdom to another fundamental thermodynamic variable: pressure. In this talk, I will outline high pressure experiments we are performing aimed at probing the transition between topologically trivial and non-trivial states of matter. In addition, I will present techniques we developed in order to rapidly screen materials for pressure-induced superconductivity. Finally, I will discus ongoing work that is motivated by two recent milestones in the history of high pressure science: The discovery of pressure induced superconductivity above 200 K in hydrogen sulfide and the possible metalization of hydrogen at ultra-high pressures.
