Dr. Asghari specializes in scientific and engineering instrumentation and computation. She has a background in nuclear engineering and extensive experience with experimental design, setup, testing, and analysis. She has over six years’ experience with radiation detection and instrumentation.

Dr. Asghari has investigated radiation detection for basic physics and its applications to nuclear security. She worked at CERN in Geneva, Switzerland developing high-fidelity muon detectors for high energy physics applications. She also worked on development of a novel neutron detector that utilizes water instead of helium-3. By measuring and analyzing the time signature of neutrons in small fissioning samples (such as plutonium), the element and mass were identified. Thus, this new neutron detector and analysis technique can “fingerprint” certain nuclear samples for application in nuclear forensics, nuclear nonproliferation, and border security.
