My research has two major thrusts: 1.) the development of high-resolution, multi-pinhole SPECT capabilities, and 2.) the use of CT, SPECT, and PET in preclinical research studies across a wide range of applications.

We are developing novel semiconductor radiation detector technology for use in innovative multi-pinhole SPECT systems. 2.) We are involved in a number of collaborative projects in which we our role is to refine and validate image acquisition and analysis techniques to improve quantitative PET and SPECT capabilities.
