I am a conservation scientist and practitioner working at the interface of research, policy, and community action to protect marine biodiversity and support coastal livelihoods. With ~15 years of experience working in NGOs and academia across Southeast Asia and East Africa, as well as advising multi-national corporations on their Nature Positive commitments, I am currently leading the design and evaluation of people-centered, evidence-based marine conservation programs in Indonesia, in partnership with Yayasan Kebersamaan Untuk Lautan and IPB University.

I completed my DPhil at University of Oxford in 2021 on Interdisciplinary Approaches to Shark and Ray Conservation, with a focus on small-scale fisheries in Indonesia and developing applications of the mitigation hierarchy and biodiversity net gain in fisheries. Since then I have been working with local researchers and NGOs to put my findings into practice. I am designing and testing incentive-based approaches to delivering marine biodiversity and human wellbeing outcomes through a grant from The Darwin Initiative, and embedding these approaches into management with support from the Shark Conservation Fund. This work includes running the world's first Randomized Controlled Trial of an incentive-based marine conservation program for Critically Endangered sharks and rays.

I am generally interested in links between conservation and human wellbeing, designing and testing the effectiveness of conservation interventions, wildlife trade, and equitable & cost-effective nature recovery. I used mixed methods participatory research to design interventions, economic valuation methods to estimate costs, and a wide range of impact evaluation methods, from theory-based to experimental research designs.

I hold an MSc in Conservation Science from Imperial College London and a BA in Natural Sciences and Management Studies from University of Cambridge, and have won several awards for my research and conservation work including the ZSL Marsh Award for Marine and Freshwater Conservation, the SCB European Early Career Research Award, and I was recognised as a Top Ten Finalist in the 2025 Indianapolis Prize Emerging Conservationist Award.
