Who’s who at Operation Wallacea UK

Project Director and founder of Operation Wallacea: Dr. Tim Coles OBE

Dr. Coles founded Operation Wallacea in 1995, and the Operation Wallacea Trust (Charity no. 1078362) in 1998. In doing so he designed and ran a series of projects that have not only resulted in the levering of over $2 million of funding for tropical conservation practices, but have also established protected areas and national parks, discovered over 30 new vertebrate species to science (plus many more invertebrate species), and have achieved numerous publications in peer-reviewed journals.

Tim has a PhD in fisheries management and over 13 years of experience in biological assessment in the UK water industry and National Rivers Authority. In 1990 he established both IEMA (the Institute of Environmental Management and Assessment) and EARA (the Environmental Auditors Registration Association). IEMA now has over 12,500 individual and corporate members based in 87 countries, and is a leading international membership-based organisation dedicated to the promotion of sustainable development, and to the professional development of individuals employed in the environmental sector. EARA has now evolved into the IEMA Environmental Auditors Register, which has over 1,650 auditors listed in over 50 countries worldwide.

Tim and Operation Wallacea have received numerous awards for their work in the environment sector, including an RSA Better Environment for Industry Award, an EC Environment Award, the Best New Tourism Project Award from the Guild of British Travel Writers, and the British Airways Tourism for Tomorrow Award for Best Project in a National Park. Tim also received an OBE in the Queen’s birthday honours list 2012 for services to environmental conservation.

Director of Sales and Marketing: Pippa Disney

Pippa first went to Indonesia with Operation Wallacea in 1998 and fell in love with everything expedition and Opwall. Upon her return she embarked upon the university tour spreading the word of Operation Wallacea and fundraising to undergraduates. Now many years on, having travelled to Cuba, Greece, Honduras, Indonesia, Mexico, Peru, South Africa and Transylvania she heads up our sales, marketing and fundraising teams. Pippa has overseen the growth of Operation Wallacea running from a single country to what it is today and from recruiting volunteers from just the UK to now having sales offices in more than 10 countries, including USA, Canada, Sweden, Portugal, South Africa, Australia, New Zealand and South East Asia. In 2010 Pippa was made a Director and is responsible for all school and volunteer recruitment. On expedition she spends as much of her time birding as possible and has a C-permit ringing license with the BTO.

Director of Operations: Alex Tozer

Alex first started working with Operation Wallacea in the summer of 2004, when he volunteered to work in a baking hot office in a dusty Honduran town for 3 months in the name of conservation. He has been addicted to Opwall ever-since, and is now involved in setting up and running the projects at each site. He has an MSc (distinction) in Psychology from Nottingham University, has professional qualifications in Occupational Testing, is an Emergency First Response Instructor, holds a C-permit bird ringing license and speaks bad South American Spanish with heavy english overtones.

Senior Operations Manager: Caroline Acton

Caroline began as a Research Assistant with Operation Wallacea in Indonesia whilst taking her BSc in Zoology at The University of Wales, Aberystwyth. She immediately caught the expedition bug and headed to Honduras as Operation Wallacea field staff almost as soon as her final exam was completed. From there she went on to work full time in Operations in the UK office, undertaking five expeditions to Honduras and one in Cuba. In 2010 her love for travel and all things Latin American lead to her taking time out from Opwall to wander the Ecuadorian Amazon for ten months searching out weird and wonderful creatures, eating an obscene amount of rice and beans, and subjecting South America to her Spanish. Now back in the UK office she is involved in the Operations and logistics for the expeditions and is currently running the Mexico and Ecuador projects.

Head of Research: Dr. Dan Exton

Dan has an undergraduate degree in Marine and Freshwater Biology, a Masters in Environmental Governance, and a PhD on the links between ocean primary productivity and climate change. His current areas of research interest include tropical subsistence fisheries and their management, coral reef community ecology, and the role of volatile organic compounds (BVOCs) in marine ecology. Dan is a highly experienced SCUBA diver and has participated in and run marine expeditions to many countries around the world over the past ten years. He has published a number of scientific papers and book chapters to date, and joined Operation Wallacea in September 2011, originally to coordinate their marine research programme. Dan is also heavily involved in large-scale conservation projects through the Opwall Trust charity, and collaborates with a number of universities, institutes and international conservation organisations.

Finance Manager: Gwen Roberts

Gwen joined Operation Wallacea in 2008 and after two summers in the office managed to get out to South Africa this year on an Opwall expedition, where she was our representative in Sodwana Bay and got to complete her PADI Open Water. After a fantastic summer in the field Gwen has returned enthused and ready to continue her studies in accounts after nearly a decade away from the books. Before joining the Opwall team, Gwen spent 8 years working for accounts practioners, the first 2 in Uxbridge where she completed her AAT. In 2006 she completed a charity trek across Cuba, where she managed to raise money by cycling between all the offices of her then employer in 3 counties, covering 200 miles in just 4 days, and motivating colleagues, some she’d never met before, to join her along the way!

Senior Research Coordinator: Dr. Kathy Slater

Kathy first became involved with Operation Wallacea in 2001 when she joined the Indonesian expedition as a general volunteer after completing her degree in Biology and Psychology at Liverpool John Moores University (LJMU). She was immediately hooked on jungle living and returned to Indonesia with Opwall the next year to collect data for her MSc project on the Buton macaque. Following her MSc (distinction) in Evolutionary Psychology at the University of Liverpool, Kathy ran away to Mexico to conduct her PhD on the social relationships of wild spider monkeys. Upon completion of her PhD also at the University of Liverpool, Kathy returned to LJMU as a lecturer in Animal Behaviour. A few months later, Kathy found herself listening to the Opwall presentation at LJMU in the same lecture theatre as in 2001 volunteering to run a howler monkey project at the Opwall field site in Honduras. Less than a year later, Kathy joined the Opwall team on a full time basis to oversee the conservation management and primatology projects in Honduras and to coordinate student research projects across all Opwall field sites. Having lived in the jungle for too long to be accepted back into civilized society, Kathy continues to reside with her monkeys in Mexico.
