I obtained my BSc and MSc Economics degrees from the University of St Andrews and the London School of Economics(LSE) respectively. Upon receiving an AXA 2012 Doctoral Fellowship grant for research into Socio-Economic risk (one of five awarded in the UK) I have returned to St-Andrews to work with Professor David Ulph on Optimal Decision and Enforcement Procedures in the Tax-Benefit system.

Research Interests

My research focuses on:

  1. Optimal Universal and Categorical Benefit provision when individuals differ in both their ability to work and, conditional on being able to work, their productivity when at work. Categorical transfers are targeted at unable individuals but may be administered with classification errors which introduce horizontal and vertical inequities into society.
  2. Optimal Linear/Piecewise-Linear Income Taxation with Categorical Transfers 
  3. Risk taking and enforcement.
