The TBA Team

Dr Rosie Trevelyan

Director, Cambridge

Rosie is a passionate advocate of capacity building as a vital tool for effective conservation. A zoologist with a PhD from Oxford University, she has been at TBA from the beginning, creating the courses that TBA runs and making sure TBA’s teaching has real and lasting impact.

Rosie has been a leader, partner and contributor on a variety of conservation projects around the globe, ranging from institutional capacity building, through developing and testing teaching materials, to integrating social issues in conservation.

Meeting so many dedicated conservationists from around the world is the most rewarding and inspiring part of my work.

Anthony Kuria

Head, African Office, Nairobi

Kuria’s role is to develop and manage our programmes in Africa. He has taught on field courses in Kenya, Uganda, Madagascar and Tanzania and numerous specialist courses. Kuria has been instrumental in supporting and strengthening the TBA alumni group movement.

Before joining the TBA in 1998, Kuria was a research associate in the Ornithology Department at the National Museums of Kenya. He has a Masters’ degree in Conservation Biology from the University of Cape Town, South Africa, and a Bachelors’ degree in Wildlife Management from Moi University, Kenya.

Kuria is an alumnus of TBA and began working with us because he believed in the TBA model, and because of his burning desire to transfer knowledge and mentor young people.

I love being part of TBA because nothing is more satisfying for me than seeing my protegées grow in their career and become respectable conservation leaders.


Mariana Carvalho

Dr Mariana Carvalho

Course Coordinator, Cambridge

Mariana is an Applied Biologist with a PhD from the University of Lisbon, Portugal, and over fifteen years of field experience, most of those working in remote locations in Africa. She was a TBA alumna in 2000, and her participation in the field course in Amani, Tanzania, has deeply influenced her professional career.

From conducting social ecological research in the tropical forests of Sao Tome and Principe and the Miombo woodlands of north Mozambique, to leading a programme of biodiversity conservation grants to civil society in West Africa, Mariana’s interests and experience range from bird ecology to bushmeat hunting and social determinants of species conservation, but also science communication and capacity building.

Being on a TBA course as a student very much determined what and where I am today, and I feel privileged to be in a position to share that inspiration and support the new generations of dedicated conservationists around the globe”.

Before joining TBA, Basil was a Research Scientist (Natural Resources) at Kenya Forestry Research Institute (KEFRI) based in Lodwar, Turkana, and a Lecturer at Turkana University College where he was teaching rangeland management, agroforestry and environmental science.

Gregory Maina

Programmes Officer, Nairobi

Maina has been with the TBA team since 2007. In his current role as Programmes Officer he manages logistics for TBA courses, and for the Nairobi office. He is also responsible for maintaining the TBA Alumni database. Maina holds a Bachelor of Science degree in Natural Resources Management from Egerton University, Kenya.

Previously, he worked as a conservationist at Segera Ranch in Laikipia plateau, Central Kenya and has also been engaged in the development of strategic forest management plans for local communities in various parts of Kenya.

My position in TBA gives me an opportunity to follow careers and academic progress of TBA alumni and it’s a pleasure seeing many of them start their conservation journey to become pacesetters in their respective careers.


Monica Frisch

Office Manager, Cambridge

Monica keeps the Cambridge office running smoothly, a multi-tasking role which includes arranging travel, managing finance and producing publications.
She has long experience in secretarial and administrative roles, with forays into publishing, environmental research and teaching adult education courses. An enthusiastic amateur botanist, Monica has a keen interest in ecology, conservation and wider environmental issues.

What I find satisfying about working for TBA is the positive feedback we get from our alumni who say how much they – and conservation – have benefitted from our courses.
