Our next guest on Cosmos Crusaders is Giannina Guzmán Caloca, a second year Astronomy PhD student at the University of Maryland College Park! We begin by talking about why we named our show "Cosmos Crusaders", and our thoughts on our conversation with Giannina. We then get into Giannina's interview, where we talk about her research on exoplanets, his personal journey, growing up in Puerto Rico, how important a work-life balance is in graduate school, and much more!
