Francesco Mazzarotto is a Honorary Research Fellow of the National Heart and Lung Institute, member of the Cardiovascular Genetics and Genomics group ( led by James Ware, Paul Barton and Stuart Cook. His primary position is that of Lecturer in Medical Genetics at the Department of Molecular and Translational Medicine of the University of Brescia (Italy). He also currently works as a bioinformatics freelance worker for a private cancer research institute (Fondazione Edo ed Elvo Tempia (Biella, Italy)).

Francesco's research at Imperial is centered on utilizing bioinformatics approaches to understand the genetic architecture of cardiomyopathies and other cardiovascular diseases, such as arrhythmogenic conditions associated with the risk of sudden death. More specifically, his current research is focused on detecting genes associated with such conditions analysing cohorts and families, on developing algorithms aiding the identification of pathogenic genetic variants and contributing to a refinement of current variant interpretation approaches. Moreover, Francesco recently expanded into the psychiatry genetics field, by virtue of his recently awarded position at the University of Brescia, where he investigates the genetic basis of conditions such as schizophrenia and major depressive disorder.

Francesco's background is mixed between biology and bioinformatics. He obtained a BSc in Biology (2010) and a MSc in Bioinformatics (2012) from the University of Bologna, the latter including development of his MSc thesis at the Institute of Biomedical Technology in Tampere (Finland, now BioMediTech). Subsequently, Francesco underwent a PhD programme in Clinical Medicine Research at Imperial College London (2012-2016) within a EU-funded Marie Curie training network (CardioNeT), under the supervision of Stuart Cook and  Paul Barton.
