Om mig


Seagrass Ecosystem Research

My research is primarily focused on seagrass ecosystems and their associated small-scale fisheries. My PhD project investigates the linkages between biodiversity and food security using seagrass meadows as a model social-ecological system. I'm interested in these linkages more broadly to provide evidence for policy change across the Indo-Pacific that gives priority to seagrass meadows for the services they provide to people (e.g. livelihoods & food security), but also for measures that contribute to sustainable development (poverty reduction). My seagrass research has taken me to Indonesia, Malaysia, Sri Lanka, Myanmar, Cambodia, Thailand, Tanzania, Mozambique, Mauritius and Mexico.

I'm also interested in the conservation concerns of small-scale seagrass fisheries more broadly, including the by-catch (in terms of fish) implications of some fishing strategies and issues associated to destructive gears (e.g. mosquito net fisheries). 

My PhD is supervised by Associate Professor Johan Eklöf and co-supervised by Lina Mtwana Nordlund (Uppsala University), Maricela de la Torre Castro (Stockholm University), Richard Unsworth (Swansea University) and Leanne Cullen-Unsworth (Cardiff University).

I am also a coordinating member of the Indo-Pacific Seagrass Network (IPSN).


Citizen Science

I am a co-developer of SeagrassSpotter, an entry-level citizen science project. Established in 2016 in the UK, the project uses a smartphone app and website database as its platform and facilitates a participants’ ability to spot seagrass and upload geo-tagged photographs that include information about seagrass presence, condition and whether people are using it in any way (e.g. fishing). Expanding across Europe in late 2016, and Globally in 2018, the project has accumulated over 2000 sightings from 80 countries and engaged over 1000 users.



I obtained a B.Sc. in Marine Biology at Swansea University where I went on to obtain an M.Res. in Aquatic Ecology and Conservation. My master's thesis focused on the role of seagrasses as indicators of change in the British Isles where multiple characteristics were used to assess how seagrasses responded to varying degrees of anthropogenic stress.

During my masters, I co-founded the marine conservation charity Project Seagrass. Project Seagrass aims to conserve seagrass ecosystems through education, influence, research, and action. As director, I focus on working to enhance understanding of the importance of seagrass using creative design to communicate scientific research to the wider public, as well as communicating this directly through workshops and events.

My previous work has focused on examining the factors that affect seagrass growth and I was involved with the Zostera Experimental Network (ZEN) to examine these factors on a global scale. Other experience lies within the use of Baited Remote Underwater Video (BRUV) to assess fish abundance and diversity across multiple habitats in the Indian Ocean. Since 2015, my work has focused on how seagrass meadows provide food security and I have conducted seagrass research and utilised BRUV's in Indonesia, Myanmar, Cambodia, Sri Lanka, Tanzania, Mozambique, the UK and Mexico.

Recently, I have been involved as a technical expert in development of The Dugong and Seagrass Research Toolkit (developed in collaboration by Total, Total Abu Al Bukhoosh, the Environment – Agency Abu Dhabi and the Convention on Migratory Species Dugong MOU; and as a scientific advisor in the development of BBC’s landmark series Blue Planet 2.
