Eligible to supervise Masters and PhD - email supervisor to discuss availability.

My background research activities are mainly in the fields of Applied Mathematics, Statistics and Psychology and I have recently completed my PhD in the area of Mathematical Psychology. It looked at two broad areas:

1. Effective wastewater sampling techniques for measuring illicit drug consumption extent.
2. Application of cognitive models in a clinical context.

I have published first author papers in both of these fields with both cross-disciplinary and cross-institutional teams. I am also interested in statistical applications across all fields and am currently researching in the forensic science space.
