I am an Assistant Professor in the University of Washington’s astronomy department. My research program is focused on improving our overall understanding of how massive stars evolve and die. 

I’m currently writing a popular science book, The Last Stargazers, that shares the tales and experiences of astronomical observing; Sourcebooks will be publishing it in 2020! I’ve also written two academic books with IOP Publishing – a professional text on red supergiants and a graduate textbook on stellar interiors and evolution. You can learn more on my Books page!

I’m a 2019 Cottrell Scholar and a 2017 Alfred P. Sloan Research Fellow. In 2014 I received the Annie Jump Cannon prize (a slidecast of my plenary talk from this award at the 225th AAS meeting is available here). From 2010 to 2015 I was a postdoctoral fellow at the University of Colorado at Boulder. I received my PhD at University of Hawaii in 2010 and my S.B. in physics from MIT in 2006.
