Alan Chambers MBE
Explorer, former Royal Marine, author and philanthropist
Alan Chambers MBE is a world-renowned polar explorer, leadership expert, author and motivational speaker, and the Founder of Mission Spiritus®. A former Royal Marine, serving from 1985 to 2001, he has spent much of his life leading teams in some of the world’s most remote and demanding environments.
His expeditions include the first British unsupported trek from Canada to the Geographic North Pole, alongside numerous polar, mountain and endurance challenges around the world. His adventures have taken him to more than 70 countries and, through exploration and fundraising initiatives, he has helped raise more than £15 million for charitable causes.
Alan founded Mission Spiritus® to bring together exploration, environmental science and education, using ambitious expeditions to support scientific research in some of the planet’s most remote and environmentally significant locations.
In January 2024, Alan and fellow former Royal Marine Dave Thomas completed the inaugural Mission Spiritus® expedition, skiing 1,150km from Hercules Inlet to the Geographic South Pole. Over 60 days, they collected 52 scientifically controlled snow samples for specialist analysis at Columbia University’s Lamont-Doherty Earth Observatory, contributing to research into the presence of micro and nanoplastics in remote environments.
Alan subsequently led Mission Spiritus® expeditions across the deserts of Oman in early 2025 and throughout the Faroe Islands in July 2025, continuing the programme’s global scientific research.
He is also the founder of Extreme Classrooms, an initiative that uses adventure and challenging environments to help young people develop resilience, confidence and aspiration.
A Fellow of both the Royal Geographical Society and The Explorers Club, Alan has advised elite sports teams, business leaders and global organisations on leadership, resilience, endurance and mindset. His humanitarian work has included leading Arctic rescue missions and supporting wounded veterans through demanding, life-changing expeditions.
A committed ambassador for several charities, Alan continues to use exploration as a force for positive change – bringing together planet, people and purpose while inspiring others to challenge perceived limits and make a meaningful difference.
‘The only limits are those of vision’

A former Royal Marines officer, Billy retired from the military in 2023 after 32 years of service, having built a career around operational leadership, training and working with people in some of the world’s most challenging environments.
His career included operational deployments to Kuwait, Northern Ireland, Iraq, Afghanistan, Sierra Leone and South Sudan, alongside extensive training and exercises in Norway, Belize, Brunei, Jordan, Oman, Australia and the United States.
Billy held several instructional and leadership appointments, from training recruits at the Commando Training Centre Royal Marines to mentoring officers and NCOs while serving in the Czech Republic and supporting the training of Iraqi security forces in Baghdad. He later worked in strategic operations and planning at the Ministry of Defence before completing his military career as the UK’s Senior Military Adviser to Cameroon.
Since leaving the Royal Marines, Billy has continued to focus on leadership, service, exploration and charitable causes. He is a trained Samaritans Listening Volunteer and has taken part in a number of endurance challenges, including cycling the 1,000km Western Front Way, summiting Mount Kilimanjaro and completing a demanding trek through the mountains of Bhutan, helping to raise funds for a range of charitable causes.
As Operations Director for Mission Spiritus®, Billy is responsible for helping plan, coordinate and deliver its science-led expeditions into remote and environmentally significant regions of the world.
He completed the Oman expedition in 2025, crossing more than 1,100km through the Empty Quarter and Wahiba Sands, followed by the Faroe Islands expedition later that year.
Billy brings together more than three decades of operational leadership with a passion for exploration, teamwork and using challenging expeditions to create positive environmental and social impact.

Dr Beizhan Yan

Dr Beizhan Yan
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.
