Gaurav Khemka is an Associate Professor of Actuarial Studies. His research uses numerical stochastic dynamic programming to analyse the life-cycle decision-making process. With a particular focus on superannuation and retirement income modelling and policy, Gaurav is interested in the ways in which retirement outcomes for Australians can be improved through better product development and government policy. To this end, he made submissions to the Retirement Income Review and the Inquiry into the Implications of Removing Refundable Franking Credits. Gaurav’s research has been published in a number of top-ranked academic journals including Insurance: Mathematics and Economics, The Economic Record and Journal of Population Research. His work on existing decision support systems to improve financial wellbeing over an individual’s lifecycle was funded by the Centre for International Finance and Regulation.
