Senior🎓
Top SchoolAlexander Long is a Staff Scientist at Los Alamos National Laboratory with a decade of experience developing advanced neutron imaging techniques for materials characterization in nuclear energy and national security. He serves as the primary instrument scientist for two neutron imaging flight paths at the Lujan Center (ASTERIX and ERNI), translating complex experimental needs into operational, high-precision imaging capabilities. His work spans instrument commissioning, method development, and applied measurements—building on a PhD in nuclear physics from Notre Dame and a postdoc focused on alpha-production reactions relevant to fusion materials. Based in Los Alamos, he combines hands-on experimental leadership with an ability to bridge nuclear data, instrumentation, and materials survivability studies, often tackling problems that require custom measurement solutions rather than off-the-shelf techniques.
