Research Interests

Multimodality imaging

MRI (soft tissue contrast) and PET (tissue functional information) image data add significant information to the radiation therapy planning process. My work in this area focuses on the correction (un-distortion) of MR images and in the case of PET on their use for the definition of biological target volumes and patient follow-up.

Quantitative imaging

By acquiring sequential scans, the temporal evolution of a tracer’s distribution can determined. I am interested in applying this multivariate information to quantitative Nuclear Medicine imaging in both, clinical and pre-clinical settings: for the characterization of novel radiotracers by employing tracer kinetic models as a way to interrogate the imaged tissue and measure its response in vivo, as well as radioisotope dosimetry.
