Vítor Costa
Group leader
Vítor Costa obtained a Biochemistry degree at University of Porto (UP) and a PhD in Biomedical Sciences at ICBAS-UP. In 1998, he was recruited as Assistant Professor at ICBAS where he currently holds a position as Associate Professor. He is principal investigator at IBMC since 2002 and became group leader in 2011. Using the yeast Saccharomyces cerevisiae as model organism, his research focuses on the role of bioactive sphingolipids and nutrient signalling pathways in the regulation of cellular processes, namely mitochondrial function, redox homeostasis, proteostasis and apoptosis, and how deregulation of these signalling networks impacts on aging and cell death in the context of neurodegenerative diseases.
