I obtained my PhD from the Wharton School of the University of Pennsylvania in 2002.  I am a Fellow of the Faculty of Actuaries in Edinburgh, UK, and have held academic appointments at Oxford University, Imperial College, the University of the Witwatersrand, Johannesburg and the University of Georgia, where I currently teach.

​

While teaching at Imperial College, I developed an MSc in Actuarial Finance, allowing actuarial science to be taught at Imperial for the first time, and helping to modernize the actuarial curriculum in the UK in line with the recommendations of the Morris Review.

​

I have also been active in policy.  In my native South Africa, I acted as a policy advisor at senior level for the National Treasury where I advised the Treasury on various aspects of retirement fund regulation, including taxation policy, defaults, scheme design, social security policy and the pension fund for state employees.  When living in the UK, I did various projects for the Pension Protection Fund and the Department for Work and Pensions.
