Education and early lifeEdit

Leszek Krzysztof Borysiewicz[9] was born in Cardiff, Wales, United Kingdom, to Jan and Zofia (née Wołoszyn) Borysiewicz, ethnic Polish World War II-era refugees (from what is present-day Belarus) who came to Great Britain with the Anders' Army.[10]

Borysiewicz studied medicine at Cardiff University School of Medicine and received a PhD from Imperial College London in 1986 for his thesis on Cell mediated immunity to human cytomegalovirus infection (cytotoxic T cell and natural killer cell mediated lysis of human cytomegalovirus infected cells) supervised by J.G.P. Sissons and Keith Peters.[1]

Borysiewicz pursued a career in academic medicine at the University of Cambridge, where he was a fellow of Wolfson College, and then as a consultant at Hammersmith Hospital. He headed the Department of Medicine at the University of Wales before joining Imperial College London, where he was promoted to Deputy Rector responsible "for the overall academic and scientific direction of the College,"[11] In September 2007, it was reported he would succeed Colin Blakemore as the 9th head of the Medical Research Council, a national organisation that supports medical science with an annual budget of around £500 million.[6][12][13][14]

Borysiewicz's research focuses on viral immunology, infectious disease, and viral-induced cancer.[8] He has co-authored and co-edited a number of books on these subjects, including Vaccinations.[15]
