  • Aurelie Hector
    Tourism Officer

    Graduating with a BSc in Biology from the University of Mauritius, Aurelie has always been fascinated by nature and loves to share her passion and experience with others. Aurelie started her conservation career with the Mauritian Wildlife Foundation, where she was the Round Island senior warden for three years and a conservation biologist on Ile Aux Aigrettes for one year. Captivated by the beauty of Seychelles, she continued her conservation journey as the Vallée de Mai Science Coordinator for two years with SIF and discovered the amazing wildlife of Praslin. She then joined the Island Conservation Society where she got the chance to explore more of the Seychelles’ island such as Silhouette, Aride, Farquhar, Astove and Cosmoledo, where she became smitten by the charm of the Seychelles outer islands.

    With her newfound love for the outer islands of Seychelles, Aurelie set up her new adventure once again with SIF as the Aldabra Tourism Officer and she hopes to share her knowledge with visitors from all around the world. With the Aldabra annual Eco-School Trip in mind, she wishes to inspire the next generation of conservation biologists among the students visiting the atoll this year. 

  • Irma Dubois

  • Simon Watkins
    Aldabra Science Coordinator

    Simon’s first experience with practical conservation was in the Seychelles during 2011 with GVI in Cap Ternay, where he spent two months upside-down underwater looking for corals. After a three-month Divemaster internship in Beau Vallon, he trained as a PADI Instructor in the Maldives for 5 months where he saw his first manta rays and whale shark. For 2 ½ years he worked on a 1-acre island off the coast of Belize as Island Manager and Dive Instructor for a marine conservation organisation. He would spend time teaching guests coral reef surveys, invasive lionfish culling, looking for whale sharks and stopping juvenile regal terns using his cabana as a toilet. After nine months in the south west of Madagascar with Reef Doctor he decided return to the Caribbean. 

    Spending 4 years in Little Cayman (population 200) in the Caribbean as a boat captain and dive supervisor, he helped manage the invasive green iguanas and lionfish. There was also the opportunity to assist in the Nassau grouper spawning monitoring project; ‘Grouper Moon’. Saving his wages and tips he returned to university in 2020 on the island of Jersey. The MSc in Island Biodiversity and Conservation was very different from his last university experience two decades before. Following his penchant for island life and an RAF flight to Ascension Island, he became the island’s first Marine Protected Area Officer. When not looking for invasive species, collecting plankton or helping to tag Galapagos and silky sharks he enjoyed diving, snorkelling and trying to grow plants in a ridiculously hot and dry garden.

    Now, he has come full circle, returning to the country it all started in and to an atoll all spoke of in awe of many years ago. He is relishing the challenge of diversifying from marine conservation, watching giant tortoises keeping the rails out of the house and protecting this wonderfully important atoll.
