I’m a professozr 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.


My first popular science book, The Last Stargazers, shares the tales and experiences of astronomical observing; read more about it at the link! I’ve also written two academic books: a professional text on red supergiants and a graduate textbook on stellar interiors and evolution written with co-author Henny J. G. L. M. Lamers. You can learn more on my Books page!

I’m the recipient of the 2020 Newton Lacy Pierce prize and the 2014 Annie Jump Cannon award from  the American Astronomical Society. I’m also a 2019 Cottrell Scholar and a 2017 Alfred P. Sloan Research Fellow. From 2010 to 2015 I was a postdoctoral fellow at the University of Colorado at Boulder. I received my astronomy PhD at University of Hawaii in 2010 and my S.B. in physics from MIT in 2006.
