Here's my full curriculum vitae (revised March 2012).


Computational Cosmology

Cosmology is the science of the universe. The role of a computational cosmologist is to create high-fidelity numerical simulations of structures in the cosmos, based on physical principles and supported by large-scale computing environments. The ultimate purpose of my work is to produce a deeper understanding of our origins in the physical cosmos.

Structures to a cosmologist are self-gravitating, quasi-equilibrium objects that may range in scale from a globular star cluster with a few million stars through galaxies, like our Milky Way, with tens of billions of stars, on up to the great clusters of galaxies that contain many hundreds of large galaxies like our Milky Way. Detailed comparisons of simulations with observations helps unravel the complex astrophysical processes that affect the visible matter components of the universe. The improved astrophysical understanding allows better use of large-scale, statistical surveys of galaxies and clusters of galaxies to understand dark matter and dark energy. These two mysterious substances account for roughly 95 percent of the present mass-energy density of our universe, yet their relationships to known fundamental physical quantities (particles and fields) remains highly uncertain.

I currently co-lead, with Andrey Kravtsov of Chicago, the simulation working group for the Dark Energy Survey as well as the theory/simulation working group of the XMM-XXL collaboration. I collaborate with Tim McKay on galaxy cluster projects based on the Sloan Digitial Sky Survey and DES. I am also part of a science team planning a future X-ray mission known as the Wide Field X-ray Telescope. Much of my computational research involves collaboration with members of the international Virgo Consortium.


As of early 2012, I have published over 100 refereed papers that receive ~700 citations annually. My ISI h-index is 41 (or 46 by ADS standards).

Funding for this research is provided by US taxpayers through peer reviewed proposals to NASA, the US Department of Energy Office of Science, and the National Science Foundation.


I am currently Associate Chair for the Undergraduate Program in the University of Michigan Physics Department. I am also an elected member of UM's Library Council, the faculty advisory body of the Dean of Libraries at Michigan.

In 2011, I helped organize an international workshop, "Clusters of Galaxies: The Crossroads of Astrophysics and Cosmology", at KITP.

In 2000-2002 and 2005-2008, as chair of the LSA Information Technology Committee, I helped enable a suite of Academic Reporting Tools (ART) as well as the Faculty Project Grants for Instructional Technology.

Other service activities can be found in my cv.


In Fall 2012, I will teach a new course in the Honors programs entitled Cyberscience: Computational Science and the Rise of the Fourth Paradigm.

In 2009, I was named an Arthur F. Thurnau Professor at the University of Michigan for outstanding contributions to undergraduate education. Criteria for this award include a strong commitment to students and to teaching and learning, excellence in teaching, innovation in teaching and learning, a strong commitment to working effectively with a diverse student body, and a demonstrable impact on students' intellectual and/or artistic development.
