Dr Robert JohnsonSenior Lecturer in Pure MathematicsEmail: r.johnson@qmul.ac.ukTelephone: +44 (0)20 7882 5480Room Number: Mathematical Sciences Building, Room: MB-422Website: http://www.maths.qmul.ac.uk/~jrjProfilePublicationsSupervisionProfileRobert Johnson is a member of the Combinatorics group in the School of Mathematical Sciences. He has research interests in several areas of combinatorics, particularly extremal problems on graphs, set systems and permutations, and the combinatorics of the discrete hypercube.Having completed his PhD at the University of Cambridge in 2003, he joined Queen Mary in 2004 following a brief spell at the London School of Economics.ResearchPublications Johnson JR, Pinto T (2020).
