MY JOURNEY

From Science to Strategy

My story began in a laser lab, but it evolved in sustainability and environment research policy, strategy and engagement. My experience has taught me that we need influential leadership, impactful engagement and effective collaboration (alongside great science) to create lasting change for nature, climate and people. This belief is at the heart of Hannah Collins Unlimited.

I transitioned from leader to coach, blending my scientific background with executive coaching mastery, to partner with leaders and teams to navigate complex challenges and create actionable influence.

18+ years in sustainability and environment research, policy, strategy and engagement.
Coaching certification from globally leading Henley Business School.
Science PhD and research background.
