Steven C. Howell Title Company National Institute of Standards and Technology Bio Steven Howell is Physicist at the NIST Center for Neutron Research in Gaithersburg, MD. He has a background in experimental and computational biophysics with a Ph.D. in physics from The George Washington University. His Ph.D. research studied the solution structure of nucleosome arrays. To facilitate creating atomistic models of nucleosome arrays, he developed a B-DNA Monte Carlo algorithm for generating ensembles of atomistic models. His current research is focused on developing experimentally accurate Monte Carlo simulations of highly concentrated protein solutions.
