Meet The Team

Explorer, former Royal Marine, author and philanthropist

A world-renowned polar explorer, leadership expert, author, and motivational speaker. He is also a former Royal Marine (1985 – 2001).  Alan has led some of the most challenging expeditions on Earth – including the first British unsupported trek from Canada to the North Pole.

With adventures spanning more than 70 countries, Alan has raised over £15 million for charitable causes through his expeditions.  He is the founder of Extreme Classrooms, an initiative that uses adventure to help young people build resilience and Mission Spiritus.

He completed the inaugural Mission Spiritus expedition in January 2024, with fellow former Royal Marine Dave Thomas, skiing 1,150km from Hercules Inlet to the Geographic South Pole.  Over 60 days, they collected 52 snow samples, which are now being analysed at Columbia University.  He also led the Mission Spiritus expedition to Oman in early 2025 and the Faroe Islands in July 2025.

Alan is a Fellow of both the Royal Geographical Society and The Explorers Club and has advised elite sports teams and global organisations on leadership, endurance and mindset.  His humanitarian efforts include leading Arctic rescues and guiding wounded veterans through life-changing challenges.  A committed ambassador for several charities, Alan continues to push the boundaries of exploration and human potential – proving that courage, curiosity and compassion can change the world.

‘The only limits are those of vision’

A former Royal Marines officer who retired in 2023 after 32 years of service.  His career centred on operations and training, with multiple operational deployments to Kuwait, Northern Ireland, Iraq, Afghanistan, Sierra Leone, and South Sudan.  He also conducted environmental training in diverse and challenging terrains, including Norway, Belize, Brunei, Jordan, Oman, Australia and the USA.

Billy’s instructional roles included training recruits at Commando Training Centre Royal Marines, mentoring officers and NCOs while on Loan Service in the Czech Republic and training officers in Baghdad, Iraq.  He later served in a strategic operations and planning capacity at the Ministry of Defence, before concluding his career as the UK’s Senior Military Adviser to Cameroon.

Since leaving the military, Billy has continued to live a life of service and purpose.  He is a trained Samaritans listening volunteer and has undertaken numerous endurance challenges for charitable causes – including cycling the 1,000km Western Front Way and summiting Mount Kilimanjaro to raise funds for brain tumour research and critically ill children.

Alongside Alan Chambers, Billy completed the Mission Spiritus – Oman expedition in January 2025 and the Faroe Islands expedition in July 2025.

Co-Founding Dean Emeritus, Columbia Climate School

A globally distinguished marine geologist and climate scientist at Columbia University’s Lamont-Doherty Earth Observatory. Dr. Raymo was the first climate scientist to lead the Observatory and is a co-founding dean emeritus of Columbia Climate School, she really has been a trailblazer in her field.

Her ground-breaking research delves into the history and causes of climate change, with a particular focus on its impact on future sea levels and ice sheet stability. Her work has been prominently featured in leading publications, including The New York Times, The Atlantic and Discover Magazine, and has been showcased on renowned media outlets such as the History Channel.

Adjunct Associate Professor of Lamont-Doherty Earth Observatory

Dr. Yan holds a Ph.D. focused on the source apportionment of polycyclic aromatic hydrocarbons. Globally recognised, he founded the Environmental Organic Geochemistry Lab, where he developed expertise in extracting, isolating, and identifying organic contaminants and biomarkers from environmental and biological samples.

He successfully traced metals and aromatic hydrocarbons in New York City’s air and water, linking these pollutants to paediatric asthma outcomes. He is currently leading a collaborative study to explore the relationship between air pollution and respiratory health in children.

Additionally, Dr. Yan is researching the ecological impacts of microplastics in estuaries and oceans.

Cuizhu (Chloe) Ma is an emerging environmental scientist and postdoctoral researcher at the Lamont-Doherty Earth Observatory of Columbia University. Her research lies at the forefront of micro- and nanoplastics science, focusing on their environmental distribution, transport pathways and implications for the ecosystem and human health.

Her current research expands to global-scale environmental systems, with a particular emphasis on micro- and nanoplastics in remote regions such as the Antarctic snow. By integrating field observations with advanced analytical techniques, Chloe investigates atmospheric transport, deposition processes and environmental fate of plastic particles across extreme environments.
