Research Summary

I have over 25 years’ experience with the preparation and application of radiopharmaceuticals. I have developed several imaging agents targeting cell surface proteins (receptors, enzymes and transporters) including receptor-based imaging agents for hormone receptors, growth factor receptors, neuroreceptors, and prostate-specific membrane antigen. I have developed imaging agents for cardiac blood flow and metabolism. These imaging agents have included a broad range of molecular motifs from small molecules, antibodies, antibody fragments (e.g., Fabs, scFv, and diabodies), and aptamers, to proteins and peptides. These molecules have been labeled with a variety of isotopes for PET and SPECT imaging. As part of the development of these imaging agents, I have been engaged in the evaluation and validation of the tracer mechanism of localization and retention at the target site. I have prepared several in vitro and in vivo model systems and interpreted the data collected from these systems to determine the utility of the probes. I have successfully translated many of these tracers into humans. I have helped to write and secure several INDs for first-in-human tracer studies.
Over the last 10 years, I have been working on the development of PSMA targeting prostate cancer imaging agents in collaboration with Dr. Clifford Berkman at Washington State University. I am currently PI on a DoD PCRP-funded proposal to prepare these agents for human imaging studies. I am also UCSF PI on an NIH SBIR funded to perform the first-in-man PET/MRI imaging studies. I am currently also evaluating a new agent to measure T cell activation, 18F-FAraG. The pharmacokinetics of agent has been assessed in normal human subjects and will be further evaluated following immunotherapy response.
