Alexander Fletcher

Professor Alexander Fletcher is a faculty member in the School of Mathematical and Physical Sciences at the University of Sheffield, holding the title of Professor of Mathematical Biology and School Director of Research and Innovation. He previously held roles including Senior Lecturer (2022–2024), Lecturer (2019–2022), and Vice-Chancellor's Fellow (2015–2019). His research focuses on mathematical modeling of biological systems, particularly how tissue-level behaviors emerge from cell-level processes in embryos, cancer, and developmental contexts.

Education: DPhil in Mathematics (University of Oxford, 2005–2010), MSc in Mathematical Modelling & Scientific Computing (Oxford), and an undergraduate degree in Mathematics from the University of Cambridge.

Research Interests: Development of discrete and continuous models to study tissue homeostasis, cancer formation, and embryonic proportioning. Techniques include individual-based simulations and multiscale modeling.

Grants: Lead Principal Investigator on BBSRC-funded projects (e.g., 'Inferring epithelial tissue mechanics through data-efficient multi-fidelity modelling') and EPSRC grants. Collaborative grants include Wellcome Trust-funded work on hypothalamic development.

• Teaching: Courses include MAS116 Mathematical Investigation Skills and MAS2007 Mathematics and Statistics in Action.
• Research Group: Member of the Mathematical Biology research group at Sheffield.

Labs/Teams: Active in computational biology and mathematical modeling initiatives, contributing to software development like Chaste for multiscale modeling.
