Hi! I’m an Associate Professor of Physics and Astronomy at Franklin & Marshall College in Lancaster, PA.

My research is centered on the evolution of galaxies in the early Universe. In particular, I seek to understand “feedback” in galaxy formation: how the lives and deaths of stars shape the evolution of galaxies. My work includes making measurements of the production of elements in forming galaxies, the explosions that accelerate gas and set the tempo of star-formation, the escape of ionizing photons from galaxies, and the effects of some of the brightest quasars (aka, “active” black holes) on the gas and galaxies around them. Exciting stuff!

How can a black hole be bright? What on Earth (or rather, not on Earth) is a redshift? Find answers to these questions (and more!) on my Research page!

I am also passionate about physics & astronomy teaching and outreach. I always enjoy speaking with students (and students-at-heart), so feel free to contact me using the links on the right side bar if you’re looking for a visitor for your school.

I am originally from California, and I previously completed degrees and fellowships at UC Irvine, Caltech, and UC Berkeley. Zot Zot! When I’m not teaching or doing research in galaxy formation, I like to spend time with my kids, watch baseball or soccer/football games, tweet, and take photos (often these activities are combined).
