Research Focus: Astronomy
Teaching
I teach a variety of astronomy & astrophysics courses at the undergraduate and graduate level. In all of my classes I focus on inquiry-based learning, with much of the in-class time devoted to targeted and free-form discussions, individual, and group-work. Since coming to KU I have been involved in efforts, both within the department and without, to encourage the removal of lecture material from the classroom and to instead focus classroom activities on actual work that better helps students to comprehend the most difficult material.
I run a research-based outreach program at Lawrence High School. This program involves 9-15 students a year and gives them a 1-semester college-level astronomy course coupled with an authentic research activity using data from the worlds largest telescopes, both on the ground and in space.

Research
I am interested in studying the formation and evolution of galaxies using primarily observational techniques. Specifically, I am trying to determine how galaxies assembled their mass over cosmic time and how much the evolution of galaxies is determined by the places in which they reside as they evolve. I address these areas by using a variety of telescopes on the ground and in space to observe galaxies at multiple wavelengths and at multiple epochs. Doing so I can directly track their evolution and the dependence of that evolution on, e.g. their mass and the density of galaxies around them. Progress in these fields will give us a better idea of how our own galaxy formed and how galaxies in the local Universe today attained their present state.

Service
I am the Director of Graduate Studies for the Physics and Astronomy Department. I have been focused on improving student retention, time to degree, and quality of graduate work. I also am particularly interested in building a departmental culture that values diversity and tolerance. Part of this is reflected in my efforts to improve our recruitment and mentorship of a diverse student body, both on the departmental and university level
