Our team

Meet the people who work at Population Matters and make it all happen!

Senior leadership team

Amy Jankiewicz, Chief Executive

Amy became Population Matters’ first female CEO in March 2024 bringing over twelve years’ experience from the charity sector, as a Trustee and Senior Leader. Previous roles include Director of Operations at Battersea Dogs and Cats Home, Senior Civil Servant and Programme Director with the Department for Environment, Food and Rural Affairs (Defra), Change Management Business Lead at Guide Dogs and before this, she headed up Business Development for military charity The Royal British Legion Poppy Factory. A former British Army Officer, including an operational tour to Afghanistan with the Royal Marines, Amy has also worked in investment banking, sport, education and training.  Amy graduated from the University of Exeter in December 2023 with a Masters in Anthrozoology which has transformed the way she views the world we share with nature.  In her spare time, she enjoys running, Canicross, skiing, photography and walking her rehomed guide dog.  

Josh HIll, Head of Finance and Operations

Josh has 12 years of experience working in Finance, including Audit, Transaction Services and External Reporting across both large multi-national corporates and within the charity sector. He is also working towards a PhD in Behavioural Economics within the context of international development and has a long-term interest in the big issues facing humanity. 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.

Sho Nair, Head of Fundraising and Engagement

Sho has worked in the charity sector since 2005, in a variety of fundraising roles – primarily in health, social welfare, human rights and education. He believes in empowerment and enjoyment at work. He believes that we need to safeguard the natural world more urgently every day, and continuously find ways to improve the experiences of people, in a fair and equitable way. Sho is dedicated to his family and has a passion for cricket. He enjoys being outdoors, walking and travelling.

The rest of the team

Madeleine Hewitt, Campaigns and Media Officer

Madeleine has three years of experience working in the digital media space, working in Music PR and later scriptwriting for content on YouTube. Her interests remained environmentally focused, with the video content she scripted for YouTube focused on the impacts of climate change as well as conservation success stories. She wanted to transfer her skills in digital media to Population Matters, as she is passionate about the cause. In her free time, she enjoys café hopping with friends and going to the cinema.  


Anthony has a background in fundraising and communications in the charity and museums sectors. He is also a qualified teacher, spending 10 years teaching in primary schools where he specialised in UK early years provision, outdoor education, and forest schools. A keen interest in environmental causes and sustainability led Anthony to Population Matters, where he hopes to be part of creating a sustainable future for the planet. In his spare time, Anthony is an avid walker. He is also a football fan and he enjoys drawing, gardening, and supporting local wildlife.

Marianne Kucera, Executive Assistant

Marianne has worked as a PA/EA in both the corporate and charity sectors supporting at Board and senior management level.  She spent 13 years working for an international risk consultancy before moving into the not-for-profit sector and undertaking interim contracts with the Queen Elizabeth Foundation for the Disabled, the Royal British Legion and the UK Council for Psychotherapy.  In her free time, she enjoys playing tennis, walking and generally being in the great outdoors. 

Shweta Shirodkar, Empower to PLan Coordinator

Shweta has over four years experience in the development sector, working across programme management and research in India. Her appreciation for the dynamic nature of the global development sector, and an interest in working at the intersection of socio-economic and sustainability-related themes to protect our planet and help people thrive, made joining Population Matters a no-brainer. In her free time, she enjoys watching culinary shows and cooking, and loves to run.

Ben Stallworthy, Digital and Communications Manager

Having previously worked in various fundraising roles, including at the Environmental Investigation Agency, Ben moved into marketing after a move to Barcelona in 2015. Combining these two skillsets at an organisation working to protect the planet was a long-held goal, so he was delighted to find the opportunity to work with Population Matters. Away from work, he likes to run, read and maintain his long-suffering relationship with Ipswich Town FC.

Lisa Vella, Accountant

After nearly 2 decades of working in accounting roles in the private sector, Lisa decided to take her learned skills into the worthwhile world of the not-for-profit.  A love for the environment and her status as a childfree feminist led her to be a supporter of Population Matters before she joined as a member of the team.  A self-proclaimed introverted nerd, Lisa loves nothing more than spending time in nature, gaming with her husband or reading a good book.  And attending rock and metal shows to keep things interesting.

Rob Wadsworth, CRM and Engagement officer

Rob has worked in the charity sector for five years now having worked previously for the Council of Christians and Jews, a national interfaith charity. He comes from a background of charity support and working with databases. Rob is passionate about the natural world and sustainability and wanted to work in a field that reflected this. In his spare time he enjoys exploring the countryside through walks, reading, writing, and playing/watching sports.
