Sigrid Lüber

Co-Managing Director

Within a few minutes, Sigrid Lüber’s path of life was redrawn by a touching encounter with a school of dolphins when diving in the Indian Ocean. In the same year, in 1989, together with a handful of like-minded people, she founded OceanCare, for which she has served as the president since 1993.

Sigrid’s passion and goal is the global preservation of oceans and the species within them. This focus has driven Sigrid to work hard to ensure OceanCare’s voice is heard within various high level intergovernmental fora and resulted in numerous successes influencing international ocean policy. Since 1992, Sigrid has participated in conferences of the International Whaling Commission (IWC) advocating for an end to commercial whaling and promoting the growth of the IWC’s conservation and welfare agenda. Since 2004, she has also been playing an active role in all United Nations (UN) related bodies dealing with ocean governance and policy. Sigrid builds and maintains excellent relationships with decision-makers both nationally and internationally. Owing to her cooperation with the UN and in recognition of the organisation’s expertise and credibility, OceanCare was awarded Special Consultative Status by the United Nations Economic and Social Council in 2011.

Sigrid’s profound knowledge about the seas and the legal basis of international ocean conservation is self-taught and a credit to her many years of experience. With her visionary sense for upcoming issues and her well balanced combination of pragmatism, knowledge, commitment, courage and perseverance, she was instrumental in making OceanCare an organisation widely respected by international bodies and scientific professionals worldwide.

Vera Bürgi

Co-Managing Director

Long before she knew what she would do in her life, Vera Bürgi knew that it was essential for her to have a meaningful career. Before joining OceanCare in 2003, she studied history of art and applied her communication skills in the tourism sector, for the Tibetan cause, at the theatre and in PR agencies. Until 2012, Vera was in charge of communications and media relations at OceanCare. In 2013 she took over the administrative management of the organisation. 

By dedicating her working life to OceanCare, Vera wishes to promote respect for nature and the biodiversity of the blue planet. To her, nature, mankind and culture tell a unique, fascinating story, and she works to ensure that we don’t lose our connection to nature and to promote living a decent life on earth without destroying it.  Within the OceanCare team she experiences what she would like to see throughout the world: joyful, collaborative commitment for a common vision. “Each of us contributes his or her strengths, and together we develop a kind of swarm intelligence, and that’s exactly what makes our work so successful. I’m sure that we are a living role model.”

Vera loves beauty – in nature, in culture, and in humans with their creative power. Regarding the sea, she is touched by the vastness, which makes mankind look very small, “right where man becomes minuscule, you can feel his real greatness”.

Stefani Westphal Vonesch


Stefani Westphal has been a member of OceanCare since 1993. She was elected to the Board of Directors in 2001 and became Vice President in 2003.

Water is Stefani’s element, thirst for knowledge is one of her main traits, and animals are her big love. As a child, Stefani spent her days snorkelling in Lake Zurich and in addition to some semesters studying zoology and a 10 year career in marketing, she became a professional diver. In her many years as a sports diver and diving instructor, Stefani has come to know and love the marine environment, always feeling like a privileged guest in an amazingly different world. On her numerous dives, she is acutely aware of the beauty of, and the threats to this wonderful part of our planet. It is very important to her that her work at OceanCare contributes to the conservation of marine habitats.

Besides her work for OceanCare, Stefani is a dedicated breeder of Rhodesian Ridgebacks. This dog breed fits to her passion for Southern Africa, where she completed “Basic Ranger” training.

Fabienne McLellan

Co-Director International Relations

Fabienne was captured by the travel bug early in her life. In addition to numerous journeys, she has made a home in many places, including Vancouver, San Diego, Melbourne and London before returning to her home country of Switzerland.

Before joining OceanCare, Fabienne dealt with complex financial structures in the private sector. She completed a part-time study at the HWZ University of Applied Sciences which resulted in a Bachelor of Science in Communication in Zurich. Fabienne joined OceanCare in 2009, initially supporting the organisation as a volunteer. OceanCare played a pivotal role in her life and inspired her to complete a Masters Degree in Environmental Science and Sustainability at Monash University in Melbourne. Until 2017, Fabienne was heading OceanCare’s public relations. Given her scientific background and her communicative vein, she is increasingly working in many of the international fora which are so critical to OceanCare’s work.

A passionate surfer, Fabienne McLellan is addicted to the sea. There is nowhere she feels closer to nature than on her surfboard. Sometimes she encounters marine wildlife while surfing, such as a pod of porpoises passing by and she feels thoroughly blessed. However other times she experiences the reality of the marine plastic debris problem first-hand. Plastic pollution is an issue particularly close to Fabienne’s heart and whenever she is out on her surfboard following  the call of the waves, she also engages in beach cleans.

Cyrill Martin

Ocean Policy Expert

Cyrill Martin graduated in law, psychology and psychotherapy. He worked as a psychotherapist until his curiosity lead him into international waters. After multiple visits to Japan, a world trip and his engagement with the Swiss Department of Foreign Affairs, where he was responsible for various treaties and conferences on shipping and ocean protection, Cyrill decided to bring his passion for international affairs, law of the sea and environmental protection to OceanCare. Since December 2020 he is building up the Deep Sea Mining programme at OceanCare and contributes his competencies to various international projects of OceanCare. Besides, he is very much looking forward to more travelling and marvellous encounters with the creatures of the oceans.


Mark Simmonds

Director of Science

Mark grew up by the sea on the south coast of England where his fascination with marine animals began. He has spent the better part of his scientific career, which spans more than three decades, trying to address threats to marine wildlife, especially marine mammals, and has worked in both the university and non-profit sectors. His more than 200 scientific publications cover many issues including chemical and noise pollution, marine debris and climate change, and he has several books to his name. Much of his work has been focused on whales and the issues they face, including whaling, and for more than a quarter of a century he has been a member of the Scientific Committee of the International Whaling Commission (IWC).

In 2020, Mark was honoured to be appointed as the Scientific Councillor for Marine Pollution to the UN Convention for the Conservation of Migratory Species of Wild Animals and in 2019 he convened and chaired the third IWC workshop on marine debris. He has successfully run a number of other international workshops for the IWC and also chairs the UK’s Marine Animal Rescue Coalition.

He is a Visiting Research Fellow at the University of Bristol.

Mark is joining the OceanCare team as Director of Science to further strengthen the science that underpins our work programmes, including within international fora.

Rahel Beck

Science & Education

Even as a child, Rahel was taken with animals. In her early years it was mainly snails, insects and mice that aroused their enthusiasm, but the animals grew bigger with her age. In the course of her master thesis in behavioral biology, she observed elephants in the zoo to find possible improvements in keeping. Besides her professional activities, Rahel’s free time is always accompanied by animals: various pets have already enriched her life and created her awareness for a responsible treatment of animals.

At OceanCare, Rahel works in the field of science and education. Rahel is passionate about passing on the phenomena of nature to younger generations, inspiring and motivating them. Already at the Sempach Ornithological Institute and later at Zurich Animal Protection Association, she was able to introduce people to the wonders of nature and its fragility. Driven by her curiosity, she enjoys reading into new topics, carrying out studies and producing reports.

The affection for the oceans is recognition for nature. Studying biology taught Rachel that everything is interlinked. Humans are also part of this network and even small changes can bring about large-scale changes. Whether algae, flies or sharks: all living beings should be treated with respect and not be classified and exploited on the basis of their benefit to humans.

Despite the many obstacles this work brings with it and her love of black humour, Rahel does not see the future gloomy. Of course we are all part of the problem, but without a healthy dose of optimism and humour we would never find a solution together. Therefore Rahel would like to be a deep sea squid and would dive into black depths and experience adventures that nobody else has experienced.

Margarete Neuenschwander

Head of Communication & Fundraising

Born in the USA and raised in the German-speaking part of Switzerland, different languages, dialects and mentalities have always been a matter of course for Margarete Neuenschwander.

After finishing school, this love of languages and foreign cultures took her to Paris, London and finally Zurich, where she studied literature and linguistics. Further stays abroad included Sweden and Southern Asia.

After completing her studies, she worked as a copywriter in advertising, but soon realized that she wanted to use her skills for a charitable cause. This wish shaped her professional career from then on: She set up the branch of the emergency aid organisation “Médecins Sans Frontières” in German-speaking Switzerland, which she headed for 5 years. Other non-profit projects followed, including seven years with “Solar Impulse”. After the historic solar flight around the world, she took over the task of raising funds for the “Special Olympics”. Since 20 years, Margarete Neuenschwander is also a board member of a foundation that supports projects worldwide in the fields of health, education and ecology.

Since May 2019, she has been working for OceanCare, where she can once again apply her many years of experience in public relations, fundraising and network building to something that is close to her heart.

Corinne Bucher

Campaign Management & Online Communications & Fundraising

Although she grew up far from the sea, Corinne has always been fascinated by the vastness and wildness of the oceans.

She spent her childhood at Lake Zurich, where she discovered her love of water. Already back then, she wanted to open her horizon to the south and see more of the world than just Zurich. Little wonder that she completed her basic training with the tour operator Hotelplan and travelled the world as a travel consultant and tour guide for many years.

Later she decided to change into the communication business. A master study in strategic communication and nearly 10 years as a consultant with Spinas Civil Voices, an agency specialized in non-profit organisations, kept Corinne on the go.

Since early 2019, Corinne has been ardently working with OceanCare. She is convinced that there’s no healthy planet without intact wildlife.

Corinne loves challenging projects and campaigns. She masters the complete range of media channels and, like a captain, keeps track of the goal even through stormy weather.

Hanna Schlegel

Online Communication & Donor Relations

Hanna holds a bachelor’s degree in communication science and and studied law until 2019. Prior to joining OceanCare, she worked in the financial sector, in research and as a teacher, among others. With her multifaceted interests and diversified skills, she supports OceanCare in the area of Online Communication & Donor Relations.

Influenced by great teachers during her school days, who knew how to communicate complex environmental issues in a comprehensible and motivating way, Hanna soon developed the wish to work in the field of environmental protection.

As a sailing fan, paddler and keen swimmer, it was only natural for her to devote herself to marine conservation. As overfishing, uncontrolled waste disposal and raw material extraction take a toll on the world’s oceans, their inhabitants appear to be particularly in need of protection. Hanna has often learned that people misjudge the dangers our oceans are exposed to, or – even worse – close their eyes to reality.

Taking this into account, she sees it as her task to raise awareness for the marine balance and thus to win over as many people as possible to the concerns of marine, animal and species conservation. For one thing is clear: the fate of the oceans and their inhabitants affects us all.

Ed Lüber

Shop administration

Ed Lüber was among OceanCare’s first supporters. He loves the sea and diving, sailing and wind surfing have long been part of his life since 1967. From 1970, he worked as a diving instructor in Turkey, East Africa, the Maldives and the Mediterranean, in addition to working as a construction manager in water engineering and a professional diver in all Swiss waters. Ocean conservation has always been an important issue to him, and he prefers – as he generally does in life – action to lots of words. For example, during his time in the Maldives he returned mussels and corals collected by tourists to the sea every night.

After completing his training as a high seas skipper, Ed became head of the technical aspects of OceanCare’s cetacean research programme, which he was actively involved in for more than ten years. Further, for many years he acted as the editor of the former news publication for OceanCare members and advocated ocean conservation through written articles. One of his greatest experiences was encountering a whale shark which boat staff mistook for a tiger shark and became concerned that Ed would enter the water!  Now, as an active retiree, Ed remains committed to OceanCare. If he is not out walking his dog, he takes care of the shop and is the good soul of the team.
