Research/Academic Interests

Dr. Roncali's research involves molecular imaging and therapy, with an emphasis on new technology for positron emission tomography (PET) and quantitative dosimetry for radionuclide therapy. She has a joint Faculty appointment with the Department of Biomedical Engineering at UC Davis. Dr. Roncali has developed optical models for Monte Carlo simulation of PET detectors and applies these models to the optimization of fast and ultra-fast detectors. Her simulation tools are frequently released in opensource software broadly used the field of nuclear medicine technology development. Dr. Roncali currently focuses her research developments on personalized dosimetry for radiopharmaceutical therapy (RPT). She is a member of two focus groups for the National Cancer Institute (NCI), as well as an investigator of the Informatics Technology for Cancer Research (ITCR) initiative to develop new dosimetry methods for RPT with the goal of improving treatment planning and optimizing TRT clinical trials. Specifically, she is developing image-based and simulation-based dosimetry for yttrium-90 radioembolization for advanced liver cancer treatment, and image-based dosimetry for Lu-177 therapy.
