Patricia trained in medicine in Sri Lanka. She attributes her twin passions of God and sex to her postgraduate training in sexology at the university of Hawaii. She retired in 2012 after a career as director of an internationally renowned graduate program in sexual health at the University of Sydney to pursue her passion for writing and public speaking in sexology from a Christ focused biblical perspective. Her non-fiction books written through a Christian publishing company are gold-standard guides for good sexual health for all ages. She has a recognised media presence and is a popular public speaker and social commentator in Australia.
