Program Overview

PhD Operational Research

Overview

The PhD Operational Research is a postgraduate research course that provides a route into research study for those who do not have a Master's degree or have little research training. The course is based in the School of Mathematics, Statistics and Actuarial Science at the University of Essex. The Integrated PhD provides an opportunity to spend the first year completing a Master's-level qualification, followed by a full-time PhD studied over three to four years.

Course Details

• Start date: October 2026
• Study mode: Full-time
• Duration: 4-5 years
• Location: Colchester Campus
• School: Mathematics, Statistics and Actuarial Science

Description

Operational research uses advanced statistical and analytical methods to help improve complex decision-making processes. The first year of the Integrated PhD will appeal to those with a first degree in mathematics or a related subject, and prior knowledge of statistics and operational research. In the second year, students move onto the PhD element of the course, exploring areas where optimization and mathematical modeling are important, such as logistics, revenue management, networks, and stochastic control.

Research Areas

• Continuous and discrete optimization
• Time series econometrics
• Experimental design
• Logistics
• Revenue management
• Networks
• Stochastic control

Expert Staff

The School of Mathematics, Statistics and Actuarial Science has an international reputation in all areas of Mathematical Sciences, including statistics, operational research, applied mathematics, pure mathematics, and actuarial science. Staff are strongly committed to research and teaching, with publications in learned journals and world leadership in their specialisms.

Specialist Facilities

• State-of-the-art STEM Centre
• Maths Support Centre
• Dedicated work space and PCs for research students
• Access to software such as MATLAB, Gap, SageMath, Python, and R
• Regular events and seminars
• Mathematics Society for students

Your Future

The course will equip students with employability skills like problem-solving, analytical reasoning, data analysis, and mathematical modeling. Graduates have gone on to work in government, business, academia, and global companies, with some remaining at the University of Essex as postdoctoral research fellows or lecturers.
