Research Interests

Research Interests

Human body composition. Development of methods to measure elemental content in living human subjects. Examples include lead (Pb) in bone using x-ray fluorescence, strontium in bone using x-ray fluorescence, aluminum in bone using neutron activation, mercury in kidney or other sites using x-ray fluorescence, manganese in bone using neutron activation, nitrogen (protein) in whole body using prompt gamma neutron activation, potassium (body cell mass) by whole body counting, cadmium in liver or kidney by prompt gamma neutron activation.

Interaction of science and faith, science and religion dialogue.
