Biography
Biography I joined Middlesex as a lecturer in Mathematics in 2016. Previously I held teaching positions at the University of Aberdeen (2012-2015) and University of Bristol (2010-2012). Before that I held research posts at RWTH Aachen (2008-2009) and the University of Aberdeen (2007-2008).
Teaching I am module leader for the following courses: MSO0201 Foundation Mathematics (Psych) MSO0204 Foundation Mathematics (Law) MSO1125 Mathematical Thinking MSO2115 Abstract Algebra MSO3115 Rings and Fields MSO3450 Cryptography and Blockchain I am supervising one PhD student: Kazal Kadr, who began her studies in October 2019.
