Research

Research Emphasis: 

The primary focus areas of the Hennkens research program are 1) the production and purification of medical radionuclides and 2) their use in the development of theranostic (combination therapeutic and diagnostic) metals-based radiopharmaceuticals.  Radionuclide production projects involve targetry, separations and target material recycling, while radiopharmaceutical projects involve ligand development, metal/radiometal chelation, and the radiochemical synthesis and in vitro/vivo evaluation of new radiopharmaceuticals.  The multidisciplinary nature of these projects results in a collaborative environment that offers a wide range of research experiences to student and postdoctoral trainees.
