Professional Biography:
Dr. Dileepa de Croos obtained his first degree on Zoology (special) from the University of Colombo. He completed his PhD at the University of Iceland in 2011. His dissertation work investigated the application of population genetic information for fisheries management, further he showed the effect of “unnatural selection” (selective harvesting) and its implications for sustainable resource management in western Sri Lankan shrimp fishery.
Dileepas’ current research focuses on struggles over marine resources and coastal livelihoods. He focuses on developing interdisciplinary strategies to investigate resilience, vulnerability, adaptation, and governance in small-scale fisheries to ensure sustainable use of living marine resources.


 Research Interests:

• Marine biology and Bio diversity: with special reference to crustaceans, teleost, and jelly(fish)

• Fisheries management: sustainable coastal fisheries, traditional ecological knowledge; 
traditional fisheries management and livelihoods

• Fisheries ecology: life history and ecology of target and bycatch species; and effects of marine 
debris

• Seaweeds and value added product development

• Population genetics
