“There are so many reasons to search for exoplanets. But the core reason for me is that I’ve always wanted to know how things are made. (And really I mean how everything is made — bread, buildings, chocolate, roads, stars, planets, galaxies…I was the kid with the endless stream of annoying questions!) In graduate school I studied star formation regions. I’m now fascinated by how planetary systems (both our own and others) are formed. There are plenty of solid theories on how planetary systems form, but we’re in a really exciting time now, when we’re finding enough systems at enough different ages that we’re starting to really test those theories. So, I search for exoplanets because I want to know how they were made.”
