Juliet de Rozario

As a "great dreamer," my curiosity and dynamism lead me to multiple experiences. My sensitivity drives me to constantly search for new knowledge about the world, living and sustainable alternatives where the environment and humanity are fundamental. In the first place, my curiosity to learn more about nature and its complexity has been nourished by volunteer missions, including inventorying biodiversity and urban landscaping projects to encourage the development of local fauna and flora, where I gained a clear understanding of ecosystem functions and developed my taste for conservation fieldwork.
At the age of 19, convinced that ecological and social issues are inextricably linked, I lived for a year in Senegal as part of a community development project. Later, driven by my passion for wildlife conservation, I worked for a year as an exotic animal caregiver in a rescue centre in the Netherlands, where I developed extensive knowledge about primate behaviours. I also pursued a remote training program in ethology, leading to a six-month chimpanzee behavioural monitoring internship at the rescue centre, where I armed myself with my first technical research skills.
After working with animals in captivity, desirous to work with them in their natural environment, I secured my current position as a research assistant studying the Bonnet Macaque (Macaca radiata) as part of the Thenmala Macaque Project in Kerala, India. In 2023, I also obtained the Youth Climate grant from the city of Lyon thanks to a project in favour of environmental and social transitions that I co-created.

In this powerful short film, Darwin Leader Juliet De Rozario investigates the alarming decline of the Guiana Dolphin (Sotalia guianensis) population in Sepetiba Bay, Brazil. Once a thriving habitat where dolphins gathered in unusually large numbers to feed and breed, Sepetiba Bay has undergone drastic transformation due to rapid industrial development. Over the past two decades, pollution, overfishing, and increased cargo ship traffic have disrupted the bay’s fragile ecosystem. Underwater noise pollution affects the dolphins’ echolocation, while toxic contamination and diminishing fish stocks have left many dolphins visibly emaciated. Juliet partners with Rodrigo Tardin from the Federal University of Rio de Janeiro, a leading researcher in marine mammal ecology, who is conducting groundbreaking work to monitor and protect this unique cetacean population. The film also highlights how local traditional fishers have become vocal defenders of the bay, standing up to industrial forces to protect their environment. Juliet De Rozario is a dynamic and curious conservationist with a passion for wildlife and sustainability. Her hands-on experience ranges from biodiversity fieldwork to primate research and animal care in rescue centers. She has lived and worked in Senegal, the Netherlands, and India, and currently studies Bonnet Macaques in Kerala. She also co-founded a project that earned Lyon’s Youth Climate Grant, focusing on ecological and social transition.
