Team leader

Strategic objectives

  1. Development of non-invasive imaging techniques for the diagnosis of melanoma.
  2. Study of the genetic bases implicated in susceptibility to melanoma and photocarcinogenesis.
  3. Development of treatment study strategies in melanoma and skin cancer: specific molecular target, immunological and photoprotection therapies.
  4. Application of artificial intelligence systems for evaluating complex data in melanoma, combining imaging, epidemiological, clinical and molecular information.
  5. Development of models of humanized mouse skin for the study of photoprotection and photocarcinogenesis.
