    Collapse Overview 
    Collapse overview
    With my background in nuclear and particle physics, and expertise in particle detectors, I develop cutting-edge radiation detectors to improve current diagnosis and therapy techniques for a number of diseases, including cancer. My main interests are exploring novel designs for SPECT and PET systems to improve their performance and expand their range of application to other pathologies. In particular, I develop new SPECT detectors for alpha and beta theranostics, explore new avenues of exploiting Cherenkov light in TOF-PET, and spearhead Monte Carlo techniques to improve dosimetry in preclinical radiation therapy.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
