### Overview

I am a theoretical cosmologist, and I currently hold a joint postdoctoral fellowship at the Canadian Institute for Theoretical Astrophysics (CITA) and the Perimeter Institute for Theoretical Physics (PI). In September 2011, I joined the CIFAR Cosmology and Gravity program as a Junior Fellow. My research focuses on the early universe and its imprints on the cosmic microwave background and the matter power spectrum. I have also worked on lensing by dark matter substructure and alternate theories of gravity. A more detailed description of my research may be found here.

My path to CITA and PI started with my first physics class at the Kalamazoo Area Math and Science Center in my hometown of Kalamazoo, MI. I then went to Princeton, where I majored in physics and decided to specialize in theoretical cosmology. After graduating in 2003, I jumped over the pond for a year and earned a Certificate of Advanced Study in Mathematics at Cambridge University on a Churchill Scholarship. In the fall of 2004, I began my graduate work in the Theoretical Astrophysics Including Relativity (TAPIR) group at Caltech. My advisor was Marc Kamionkowski. I received my Ph.D. in June 2009, and I arrived in Toronto the following September.
