Welcome to my website!
I am an Assistant Professor at Iowa State University in Ames, IA. I recently moved from Boulder, CO where I was Senior Research Associate at the University of Colorado and a visiting scientist at the Southwest Research Institute. Before that, I was a NASA Sagan Fellow at the Southwest Research Institute.
My primary research interest is in the formation of planetesimals, bodies that range in size from 1 km to 100 km or so (e.g., asteroids, comets, Kuiper Belt Objects). Determining how these planetesimsals form is one of the critical yet not well understood issues in astrophysics and planetary science.
I am also very strongly interested in the structure and evolution of protoplanetary disks, including the nature of turbulence in these disks. Furthermore, I am continuing to study accretion processes (particularly those that are magnetically driven) in the high energy cousins to protoplanetary disks, those around black holes.
In all of my work, my focus is on the use of large-scale high performance computing to study these various processes using detailed numerical simulations.
