Neutron imaging / Materials science

A different way
to see inside.

I develop neutron imaging techniques, detectors, and software to explore materials from the inside out.

03 / A little background

Physics, materials,
and mountain trails.

My research has taken me from nuclear astrophysics to materials science. Today, I work on neutron imaging at LANSCE. Outside the lab, you'll often find me running the trails around Los Alamos.
