Dr Zac Seidler is a Clinical Psychologist and one of the world’s leading researchers in men’s mental health. His work sits at the intersection of clinical practice, public health, and policy — with a singular goal: to reduce the staggering rates of male suicide and domestic violence worldwide.

Zac is the Global Director of Men’s Health Research at Movember and an Associate Professor with Orygen at The University of Melbourne, where he leads the Young Men’s Mental Health Lab. He has spent years translating research into real-world change — working with clinicians, organisations, governments, and the public to shift how we understand and respond to men in distress.

With more than 100 peer-reviewed publications, two edited books, and a track record of advising national and international health policy, Zac brings both rigour and humanity to the conversation around men’s mental health. He developed Men in Mind — the world’s first online training program for mental health practitioners on working with men.

When he’s not in the research lab or on stage, Zac is a regular contributor to major media outlets including the ABC, BBC, Sky News, The Guardian, The Times, and the Sydney Morning Herald, and a sought-after keynote speaker for corporate, government, and clinical audiences.
