Research:

The environmental fate and toxicity of organic contaminants, heavy metals and radionuclides. Emphasis on the application of ion-beam analytical techniques to assess the bioavailability of contaminants and their in vivo disposition. Use of accelerator mass spectrometry to assess the fate of low-doses (i.e., environmental concentrations) of contaminants through the application of isotopic tracers.
