Michael W. Roth 
Associate Professor of Physics
e-mail: rothm@uni.edu
Dr. Roth arrived at UNI for the start of the Fall 2000 semester.
Since then, he has taught a variety of courses across the physics
curriculum and has had the pleasure of involving many students in
his research, which involves computer simulation and modeling of systems
on various length scales. He has collaborators at UNI in Science Education,
Earth Science, Computer Science, Biology, Chemistry and even Physical
Education & Leisure Services. In addition he enjoys working with
collaborators and students outside UNI regarding dynamical computer
simulations of atomic and molecular systems. He grew up in Colorado
and lived there for the first 31 years of his life, but the collegial
atmosphere at UNI and the rural setting of Iowa are unmatched anywhere.
Interested colleagues and students should drop by.
