The focus of Charlotte's research is modelling decision-making in traffic in order to improve intelligent road systems.

My research questions are:

• How does information distribution negatively effect expected travel times of travellers?
• How would drivers make decisions about route choice when given traffic light cycles?
• What is the optimal reward function for intelligent traffic lights?
• Are intelligent traffic lights fair?
• How does autonomous vehicle route control affect the Price of Anarchy?

Education

•  MSc in Mathematics of Systems (Distinction). Chosen optional modules include Algorithmic Game Theory, Mechanism Design and Alternative Games, and Computational Methods for Complexity Science. Involved in working on a group project, with a pedestrian simulation company Legion Ltd., on multi-scale modelling for simulation of crowds. My individual MSc project was on the topic of using superorganism decision making as a model of bounded rationality.
• BSc in Mathematics at the University of Warwick (First class honours). This included modules in Game Theory, Combinatorics, Statistics, Graph Theory, Bifurcation Theory, Mathematical Economics, and Finance.
