Research Background

Awantha is an experienced researcher with a background in marine biology, including a PhD in marine biology (crustacean ecophysiology). He has over 18 years’ experience of both laboratory and field research with a focus on outlining physiological functioning in aquatic organisms, comprising of a multidisciplinary approach (from the molecular level to physiological) to evaluating whole organism function and associated effects upon organism behaviour.

Awantha has contributed to over 25 scientific peer-reviewed research publications which have demonstrated how major global issues of concern, such as global climate change and coastal environmental pollution may impact on organism ecology and physiology.

Research Interest

Dr Awantha Dissanayake is the MSc Programme Leader for the Marine Science and Climate Change course and a lecturer in Marine Science at the University of Gibraltar.

Awantha has lectured on a range of topics from Ecology, Conservation, Oceanography, Coastal Zone Management, Marine Spatial Planning and Climate Change. His research on organism ecology has demonstrated its value for various applications, e.g environmental monitoring programmes, climate change impacts, educational outreach programmes, conservation in Marine Protected Areas, and capacity-building and knowledge-transfer programmes.

As an experimental biologist, he uses an interdisciplinary approach to contribute to the understanding of how ecosystem changes; either natural or anthropogenic including multiple stressors may affect organism function with a view of understanding ecosystem health. Awantha’s interests also lie in outreach activities, where he encourages a better understanding of marine pollution and available tools for environmental science through initiatives such as ‘Healthy Organisms’ and ‘Healthy Ecosystems’ in Singapore.

He has a wide-ranging teaching experience world-wide (>3000 contact hours), performing high-quality research with evidence of securing funding through grants and fellowships, and publishing in relevant international journals (h index: 18;>2000+ citations).

Teaching

  • Programme Coordinator for MSc in Marine Science and Climate Change
  • Lecturer in marine science; topics ranging from Ecology, Conservation, Oceanography, Coastal Zone Management, Marine Spatial Planning and Climate Change
