Our team of full and part-time staff develops and implements our strategy, under the supervision of our board.

Robin Maynard, Director

A longstanding and passionate supporter of the population cause, Robin began his environmental career more than 30 years ago, joining Friends of the Earth as a volunteer just before the Chernobyl disaster. That grim event led to his first paid job, tasked with tracking radioactive fall-out across the UK and securing compensation for affected farmers. Subsequently, he held senior positions at Friends of the Earth, FARM, the Forestry Commission, the Soil Association and latterly, at the Wildlife Trusts, developing programmes bringing people into direct contact with nature. He resigned as Director of Communications for the Forestry Commission in 2010, when the coalition government proposed to dispose of the entire public forest estate. With other campaigners, he formed ‘Our Forests’, forcing a government U-turn and halting the sell-off. Following a short stint presenting BBC Radio 4’s Farming Today, he undertook several investigative trips for Costing the Earth, including visiting Chernobyl 10 years on from the disaster, Bhopal in India to meet victims of the catastrophic pesticide plant explosion, and a trip up-river in Borneo, staying with indigenous communities threatened by logging and palm oil plantations. He has been Director of Population Matters since 2017.

Julie Lewis, Head of Supporter Services

Julie Lewis, Head of Supporter Services

Julie spent 15 years in energy consultancy providing economic analysis to clients around the world. Following a career shift, she worked with several charities and grant-making trusts before moving to Population Matters in 2008 to focus on population and sustainability. The importance of leaving a world fit for future generations, and the impossibility of doing so without addressing human numbers, made Population Matters an obvious choice.


Alistair Currie, Head of Campaigns and Communications

Alistair has been a professional campaigner for 20 years, including at PETA UK, Cruelty Free International and Free Tibet. After campaigning for animal and human rights, he was keen to make a contribution in the environmental or international development fields. Answering a job advertisement looking for a campaigner "used to tough issues", he was delighted to be able to combine them both when he joined Population Matters in 2016. In a previous professional life he was a registered nurse.

Izi Clery, Fundraising Manager

Izi started her fundraising career in the arts and cultural sector before focusing on raising support for environmental conservation projects with Fauna & Flora International, where she spent two years working in its successful trusts and foundations team. With further experience gained more recently in higher education, Izi is looking forward to using her experience to grow Population Matters’ fundraising programme that will underpin and strengthen its campaigns to ensure a sustainable future for all. 

Olivia Nater, Senior Communications Officer

Before joining PM, Olivia worked as online and events fundraiser at Friends of the Earth Scotland, where she developed their first online engagement strategy. Passionate about wildlife, Olivia holds a MSc and a BSc in zoology. She interned at the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and after graduating, spent some time working in the communications team of the International Union for Conservation of Nature (IUCN) Species Programme in Switzerland. She enjoys meeting the challenges of online and offline strategic communications to inspire action for nature and social justice. Olivia was attracted to PM because it draws the crucial link between the two causes closest to her heart: conservation and women’s rights.

Katrina Dixon, Campaigner

As a qualified marketer and graphic designer, Katrina worked in marketing communications for a decade, where she received national accolades for her work. A growing interest in environmental, political, and social justice issues led to a career change. She got her first taste of campaigning with the international charity, The Humane League, where she advanced the protection of animals raised for food worldwide.

Katrina is an environmentalist and a fervent supporter of women's rights and empowerment. She is a member of the Women's Environmental Network and her local climate change forum. Katrina joined Population Matters in 2020 and is excited to be working towards a more prosperous and sustainable future for people and the planet.

Gabriel Emordi, Finance and Administration Officer (part-time)

Gabriel has worked for the last 20 years in the not-for-profit and charity sector. He's always had a great interest in nature and grew up watching David Attenborough documentaries on television. This started an interest in nature and the environment which led to related interest in issues such as population growth and sustainability. To him, the idea of there being a maximum level of consumption that the planet can sustain seems obvious, so it was a pretty easy decision for him to want to get involved when he found that Population Matters was looking for staff in his field of work. Gabriel thinks it is absolutely imperative that we face this challenge head on now and he is really keen to try to help out in whatever way he can.

Rachel Musk, Supporter Services (part-time)

As well as her membership duties, Rachel edits the twice-yearly Population Matters magazine and coordinates our Empower to Plan crowdfunding project. Rachel previously worked as the Communications Manager for ten years with a human rights NGO based in the Middle East. She is passionate about the environment, sustainability and reducing consumption personally and in her community. 


Andrea Holmes, Adminstration coordinator (part-time)

Andrea has a background in Financial Services, specifically working in Legal, Internal Audit and Company Secretariat roles. After leaving her corporate role she has been supporting businesses for the last 6 years, helping them to coordinate teams to work efficiency and effectively. Having always had an interest in our planet and sustainability, when the opportunity arose to join the team of Population Matters she jumped at the chance. In her spare time she enjoys spending time with her family, country walks and cooking.
