Dr Eleanor F Lingham
Senior Lecturer in Mathematics
Summary
Eleanor Lingham is a Senior Lecturer in Mathematics at Sheffield Hallam University. She holds a PhD in Mathematics from the University of Nottingham, and a Masters Degree in Mathematics from University College Cork, Ireland. She joined Sheffield Hallam University in 2015.
About
Eleanor’s main research area is complex analysis, in particular function theory, which is the study of the properties of different types of functions.
Eleanor has co-authored a book entitled ‘Research Problems in Function Theory’ with Prof. Walter K. Hayman. This project involved researching the development of over 500 complex analysis problems that range over nine areas of complex analysis.
Eleanor is the Editor-in-Chief of the London Mathematical Society Newsletter (from Nov 2019 for three years), a bimonthly publication that is distributed to 3,000 members in over 60 countries.
Eleanor is a Fellow of the Higher Education Academy and a member of the London Mathematical Society.
Specialist areas of interest
•Complex analysis
•Theory of analytic and meromorphic functions
•Nevanlinna theory
•Social Networking analysis
