Research Summary

I am a member of both Pediatric Malignancies and Prostate Cancer programs of the HDFCCC. I have extensive experience in quantitative data analysis, as well as instrumentation and software development using ionizing radiation imaging modalities (PET, SPECT, and CT), since I joined the UCSF Physics Research Laboratory (PRL), the birthplace of the dual-modality functional-anatomical imaging system (SPECT/CT and PET/CT). My broad training and expertise in experimental particle physics and medical imaging physics, combined with my leadership roles in extramurally funded projects, have proven a strong asset to many preclinical and clinical SPECT/CT, PET/CT, and PET/MRI projects. My particular research interest is, but not limited to, to develop technologies for combined dual-modality imaging systems to assess both structure and function in human diseases. I serve as a group leader for the UCSF PRL, and co-direct the preclinical SPECT/CT and PET/CT imaging research program at the Department of Radiology and Biomedical Imaging.
