Ann has a strong interest in supervising research projects on the interaction of these aspects on international tax policy and law design.

Ann has significant teaching experience at both UNSW Business School and University of Sydney Business School. She is a recipient of the UNSW Business School John Prescott Award for Outstanding Teaching Innovation and received multiple teaching citations from the University of Sydney Business School.
