His research connects basic sexology—how sexual orientations and distinct pathways to gender dysphoria develop—with clinically relevant questions about assessment, psychological distress and evidence-based care. He has published more than 30 peer-reviewed works, teaches and supervises postgraduate research, and collaborates with researchers in Australia and internationally. The guiding principle of this work is that people deserve accurate scientific knowledge about sexuality and gender-related experiences, grounded in clear definitions, transparent methods and careful distinctions between natal sex, sexual orientation, gender identity, behaviour, distress and diagnosis.
