Tegan Cruwys is an Associate Professor and NHMRC Emerging Leadership Fellow at the Australian National University and a former Australian Research Council DECRA Fellow.

She has authored over 140 papers on these topics, as well as The New Psychology of Health: Unlocking the Social Cure (with Catherine Haslam, Jolanda Jetten, Genevieve Dingle, and Alex Haslam, 2018) — winner of the British Psychology Society’s Textbook of the Year award in 2020.

He collaborates with and consults to organisations, community groups, and industry to use theory and evidence to solve applied problems and improve group and organisational functioning. He recently co-edited Organizational Psychology: Revisiting the Classic Studies (with Michelle Ryan and Floor Rink, 2022). In 2018 he was awarded a Discovery Early Career Researcher Award (DECRA) by the Australian Research Council.
