I work in the field of mathematical psychology, specifically trying to build and test computational models of non-normative decision making. These can be anything from simple perceptual decisions about shapes or moving dots, to much more complex choices, such as how to split a windfall between yourself and a charity. In many such decisions people don't always behave rationally.
I am particularly interested in models of human decision making based on the mathematics of quantum theory. These models try to explain different types of decision making errors as arising from a more general issue with the way events are represented in the brain. More generally my work tries to uncover the mechanisms that underlie decision making errors and biases, with the aim of predicting when people are likely to make errors, in order to help them make better choices.
I also have an interest in moral decision making, particularly the role of emotion in shaping how moral choices are made.
One of the themes in my research is building and testing models of behavior, rather than just performing statistical tests on data. This can help us achieve a better understanding of the processes underlying human reasoning, but it brings its own set of challenges. I am therefore also interested in issues such as model fitting and model comparison using Bayesian methods. Some of my recent work has involved fitting models of serial recall using approximate Bayesian computation methods, which had previously never been quantitatively fit to data before.
I currently teach one half of the 1st year quantitative methods course, PS1007. I also provide additional maths support to new undergraduate students to help them tackle the research methods modules in the first year.
