Professor Adam Letchford
Professor of Analytics and OptimisationResearch Overview
My research is on Optimisation and its applications. It has two main strands:
- Theory and algorithms for discrete and nonlinear optimisation.
- Applications to vehicle routing, facility location, facility layout, machine scheduling and inventory control.
My research is inter-disciplinary, drawing on Mathematics (e.g., graph theory, combinatorics, linear algebra) and Computer Science (e.g., design and analysis of algorithms, computational complexity theory).

PhD Supervision Interests
Most of my PhD students work on exact solution algorithms for NP-hard optimisation problems. Candidates need to be comfortable with mathematics. Experience in programming (in, e.g., C, Julia, MatLab or Python) is highly desirable, as is basic knowledge of linear algebra and graph theory.
