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. One topic that she is particularly interested in is function theory, which is the study of the properties of different types of functions.

    Other topics in complex analysis that she is interested in are complex dynamics, composite functions, Nevanlinna theory and normal families.

    Eleanor is currently co-authoring a book entitled ‘Research Problems in Function Theory’ with Prof. Walter K. Hayman. This project involves researching the development of a list of over 500 complex analysis problems that range over nine areas of complex analysis.

    Eleanor is a Fellow of the Higher Education Academy and a member of the London Mathematical Society.
