Prof. Andrea Urbani has been involved in structural and functional investigation of integral membrane protein complexes of the respiratory chains since he moved in 1998 to Heidelberg (Germany) at the European Molecular Biology Laboratory (EMBL) in the Structural Biology Program. Mass spectrometry characterisation and identification of proteins and metabolites represents the primary motive of the laboratories he has established during the last fifteen years. He is currently the Director of the Biochemistry and Clinical Biochemistry Institute of the Catholic University of the Sacred Heart, and President of the European Proteomics Association (EuPA) for the years 2015-2019. Prof. Mohan Babu is internationally recognized as an emerging leader in network biology, and a pioneer for mapping epistatic relationships and membrane-associated protein complexes in prokaryotes. His multidisciplinary research program focuses on characterizing protein and genetic interaction networks from microbes to mammals, and establishing new molecular mechanisms for mitochondrial proteins associated with neurodegenerative disorders. He is an editorial board member of the journal “BioEssays”, editor of the book “Prokaryotic Systems Biology” (Springer), Associate editor of “BMC Microbiology”, secretary treasurer for “Canadian Society of Microbiology”, and an advisory board member of the “International Mitochondrial Human Proteome Initiative”.
