 Profile

Professor Applebaum graduated with an MA from the University of St Andrews in 1979. He obtained an MSc in mathematical physics from Nottingham University (1982) and a PhD there in quantum probability (1984), supervised by R L Hudson. After postdoctoral appointments in Rome, Nottingham and Bielefeld, he took a lectureship at Nottingham Trent University (then Trent Polytechnic) in 1987, becoming a Reader in 1994 and Professor in 1998, before moving to Sheffield in 2004. Professor Applebaum now works in probability theory.
