Dr Anu Arasu

Dr Anu Arasu is a physician, founder of London Bioidentical Hormones, author and sought-after keynote speaker who brings a distinctive perspective to the conversation around leadership, culture and mental wellbeing. Drawing on more than two decades of clinical experience, she helps organisations understand how the biological realities of stress, safety and human behaviour shape workplace culture, performance and long-term success. Known for translating complex science into practical leadership insight, she explores the often-overlooked connection between individual wellbeing and organisational culture. Her work is grounded in a simple but powerful principle: the same conditions that enable people to thrive psychologically are the conditions that allow teams and organisations to perform at their best. Through greater clarity, trust and open communication, leaders can create environments where people feel safe enough to contribute, innovate and grow.

As one of the UK’s early pioneers of functional medicine, Dr Arasu has spent her career examining how biological systems influence human behaviour — how chronic stress affects decision-making, resilience, engagement and performance. Today, she applies these insights beyond healthcare, helping leaders recognise how organisational pressures shape culture, relationships and outcomes across an entire business. Her keynote, The Biology of Possibility: Wired to Evolve, Built to Lead, challenges conventional approaches to workplace wellbeing by demonstrating that sustainable performance cannot be separated from the environments in which people operate. Through engaging, evidence-based and highly interactive presentations, she equips leaders with practical tools to foster healthier, more adaptive and human-centred cultures. While healthcare remains her flagship sector, her insights resonate across highly regulated and high-pressure industries including financial services, pharmaceuticals, energy, aviation and professional services — connecting culture directly to the outcomes leaders are accountable for, from retention and engagement to safety, performance and resilience. Dr Arasu is lead author of Nutrition, Hormones and Mental Health (Singing Dragon, September 2026). She has appeared across national media including The Guardian, BMJ, Sky News, Channel 5, HuffPost and the BBC. Her keynote work has been trusted by leading US healthcare organisations, including the Montana and North Carolina Healthcare Associations and McKesson. 

Combining medical expertise, systems thinking and a deep understanding of human behaviour, Dr Anu Arasu offers audiences a fresh and compelling perspective on leadership, culture and mental wellbeing. Her message is clear: when organisations create the right conditions for people to think clearly, communicate openly and perform sustainably, wellbeing and performance cease to be competing priorities and become mutually reinforcing drivers of success. Her presentations move beyond theory, equipping leaders with practical, evidence-based tools they can immediately apply to build greater trust, psychological safety and high-performance cultures. An engaging keynote speaker, panellist and workshop facilitator, she is particularly well suited to leadership conferences, culture transformation programmes, wellbeing and mental health events, healthcare summits, women in leadership forums and conferences within highly regulated sectors.
