Research interests
Dr. Detwiler is a nuclear physicist coming to the department
from a 6 year employment supporting DOE/NNSA national nuclear
emergency response at the Remote Sensing Laboratory in Las Vegas
Nevada, where she served as Senior Scientist, Project Engineer,
and Technical Mission Leader. Her areas of interest and expertise
include nuclear emergency response and nuclear nonproliferation,
radiation detection, gamma spectroscopy, MCNP and MCNPX sensor
response modeling including aerial and ground-based sensor modeling,
and nuclear charged particle interactions. Her graduate work
involved charged particle nuclear scattering experiments and
R-matrix (nuclear scattering theory) analysis.
