Research Group

Data science

Data science unifies statistics, data analysis and their related methods in order to understand and analyse phenomena in applications ranging from healthcare to finance.

It is an interdisciplinary research area that employs techniques and theories drawn from many fields. In our department our main areas of research interest are statistics and actuarial science, and operational research.

Many of our academics are also members of the university's Institute for Analytics and Data Science, and work closely with the Institute for Social and Economic Research, the School of Computer Science and Electronic Engineering, and the School of Life Sciences.

Statistics and actuarial science

Statistics is concerned with modelling and analysing data, designing experiments, and making inferences, predictions and decisions in the presence of risk.

Operational Research

Operational Research deals with the application of mathematical optimisation to help make better decisions and arrive at optimal or near-optimal solutions to complex decision-making problems.

At Essex our work has an emphasis on human-technology interaction and focuses on practical applications that overlap with other disciplines, notably industrial engineering and operations management.

Essex Data Science Seminar Series

Our group runs a regular research seminar series throughout the academic year. Along with hosting talks from our academics and research students, we also invite experts from other institutions to present their latest work.

Our seminars are open to anyone at the University of Essex who may be interested in the topic being discussed.

Upcoming research seminars

19th November 2020 - "A Statistician’s Botanical Garden - The Ideas behind Trees, Model-Based Trees and Random Forests" - Professor Carolin Strobl, University of Zurich.
