Serge Muyldermans is a Professor Emeritus in the ‘Cellular and Molecular Immunology’ research group at the Vrije Universiteit Brussel, Brussels, Belgium. He holds a doctorate in sciences from the same university and was trained as a biochemist. He developed a technology to identify nanobodies, i.e., recombinant single-domain antigen-binding fragments from camel heavy-chain antibodies. Nanobodies can be selected with specificity to any antigen of interest. His research interest is in exploring new applications for nanobodies.
