  • Climate change adaptation, resilience, & vulnerability (community-based research)
  • Social-ecological systems (fisheries and aquaculture)
  • Indigenous peoples & knowledge systems (Arctic & Sri Lanka)
  • Multi-level governance (commons, adaptive co-management)
  • Systematic literature reviews (tracing & tracking)

My research is aimed primarily at the social dimensions of human-nature systems. I am particularly interested in climate change adaptation, with a major focus on how Indigenous communities and their local food systems experience and adjust to change. I have worked with Inuit (Canadian Arctic) and Vedda (Sri Lanka) communities using place-based participatory research methods, including interviews, participant observations, participatory mapping, scenario building, seasonal calendars, and collaborative artwork. My theoretical approach combines concepts from social-ecological resilience, vulnerability, adaptation, and food security. Also, I have used theoretical aspects of commons, with an emphasis on community-based management, (adaptive) co-management, Indigenous knowledge systems, co-learning, and knowledge co-production. I bring a broader perspective to my research, using systematic literature reviews that contribute to global-level assessments. 

Now I am involved in diverse initiatives in this research area, including projects focusing on Indigenous peoples and climate change and examining ways to create ‘usable science’ and policy. I have international research collaborations, including the Arctic Salmon research group (Canada), Local Indicators of Climate Change Impacts (Spain), and the Covid Observatories research group (UK). Also, as a contributing author and an expert reviewer/contributor, I have contributed to the sixth assessment report of the United Nations Intergovernmental Panel on Climate Change as well as the Food and Agricultural Organization of the United Nations report on Indigenous Peoples’ food systems.
