Research Interests

My current research focuses on the interaction of ionizing radiation with matter, specifically with implications to instrumentation and radiological physics measurements. Included in this work are the effects associated with fast neutrons in highly ionizing energetically charged particles useful for radiation therapy. Recent efforts have explored the applicability of very low energy photon radiation produced by energetic electrons. Examples include precise measurements of energy and proton power used in x-ray lithography, as well as imaging by photon induced electron emissions of live biological samples. Other interests include radiation protection (health physics), neutron dosimetry, radiobiological research with fast neutrons.
