Dr Adrià Martí i Líndez is a postdoctoral scientist working in Prof Christoph Hess’ group in the Department of Biomedicine of the University of Basel. After an MSc in genetics at the University of Barcelona in Spain, he recently completed his doctoral degree in Prof Walter Reith’s group in the Department of Pathology and Immunology at the University of Geneva. During his doctoral studies, he investigated how arginine metabolism modulates cancer-directed T cells. His research continues to focus on the metabolism of virus- and cancer-fighting CD8+ T cells and on how unveiling metabolic vulnerabilities in senescent CD8+ T cells can help to optimise COVID-19 immunotherapies.
