Dr. Wallin is a Professor at Middle Tennesee State University in the Department of Physics and Astronomy. His primary research is aimed at understanding the gravitationally interactions in the universe. In this research, Dr. Wallin uses a variety of computational and observational techniques linking numerical models with data. His research has included developing algorithms for improving the performance of meshless methods in lagrangian hydrodynamic simulations as well as probing deviations from the inverse square law in the outer solar system.
Most recently, he has become involved in the Zooniverse project to enable volunteer Citizen Scientists to contribute their eyes and brains to analyzing scientific data. He and his gradudate student Anthony Holincheck created the "Merger Zoo" http://mergerzoo.galaxyzoo.org This project allows volunteers to help match simulated galaxy collisions with real interacting systems. Previous research has included using the World Wide Web as an aid to teaching large lecture classes. He currently is involved in linking computaitonal intelligence to Citizen Science data.
Wallin received his B.S. Degrees in Physics, Astronomy, and Mathematics at Mankato State University in 1984. In 1989, Wallin obtained his Ph.D. in Astrophysics at Iowa State University. He was a National Research Council Cooperative Research Associate working in the Space Sciences Division at the Naval Research Laboratory from 1989 to 1992. From 1992 to 2010, Dr. Wallin was a faculty member in the Computational Science Program at George Mason University. During the 1999-2000 school year, he was on sabbatical leave as a visiting scientist at Los Alamos National Laboratory's Applied Physics Division (X-3). In 2010, he took the job as the first director of the Computational Sciences Program at MTSU. During the spring of 2010, he will be a Visiting Fellow at Mansfield College Oxford and the University of Minnesota.
Dr. Wallin was awarded a Teaching Excellence Award in 1998 from George Mason Unversity, and was nominated for the Virginia Outstanding Faculty award by the office of the Provost in 1999 and 2006.
Dr. Wallin lives with his wife Katharine and their four cats in Murfreesburo Tennessee.
