Corey joined Cumpston Sarjeant in 2002 following attainment of an Honours degree in Actuarial Studies. He has since qualified as a Fellow of the Institute of Actuaries and has gained a wide experience in a variety of actuarial areas.

He has performed valuations services for lawyers since 2002 and is highly proficient in the history and calculation of fund management awards, having provided comparison tables and calculators to public and private managers and calculations of uplifts for court settlements in NSW, Victorian, Queensland, Western Australian and Tasmanian cases since 2005. He also provides regular advice to a variety of general insurance clients in areas of provision setting, premium rating and capital management.

In addition to traditional actuarial work, Corey is also highly experienced in IT systems and analytics programming tasks including manipulation of large databases and data parsing. He has utilised these skills in many projects including major experience investigations and audits that require automated parsing and numerical analysis of upwards of 1 million malformed records, the design of a diverse range of calculation models for the finance, legal and government sectors and also in the internal development and integration of web calculators and administration processes.

When Corey is not crunching numbers, he is solving puzzles. His interest in puzzles led him to the MIT Mystery Hunt in which he has been a participant for over ten years. Corey has also been a contributor to both the MIT Mystery Hunt and the Melbourne University Mathematics and Statistics Society (MUMS) Puzzle Hunt.
