Contact   External Profile



Yann Seimbille obtained his PhD degree in 2002 at the University of Sherbrooke (Canada). He joined the division of Nuclear Medicine at the University of California Los Angeles (UCLA) as postdoctoral fellow and in 2005 he was appointed as Assistant Professor in the department of Molecular & Medical Pharmacology. In 2006, he became Head of the Cyclotron Unit in the division of Nuclear Medicine & Molecular Imaging at the University of Geneva. From 2015 to 2017, he worked at Canada’s particle accelerator centre (TRIUMF) in Vancouver as research scientist and deputy associate laboratory director for the Life Sciences Division before joining Erasmus MC in July 2017. 

His scientific interests include the design of molecules for multimodality imaging and theranostic applications, as well as technology and methodology developments in radiopharmaceutical sciences.

Field(s) of expertise

The RadioPharmaceutical Chemistry (RPC) group is mainly focusing on the development of radiopharmaceuticals for targeted diagnosis and treatment of cancer. By combining a targeting vector (i.e. small molecules, peptides, antibodies) with an imaging radionuclide, we can identify molecular alterations of cancer cells using noninvasive nuclear imaging. Subsequently, treatment of tumors can be specifically achieved with targeted radionuclide therapy. It corresponds to the so-called “theranostic” paradigm. Our research program is a molecular-imaging-based program focused on theranostics and multimodality imaging probes, with an emphasis on developing these novel radiopharmaceuticals for clinical translation.
