Meet our staff
Karl Payne is a Lecturer and Programme Coordinator for the Water Resources Management stream. He holds a Ph.D. in Civil Engineering (Water Resources) from the University of South Florida. Karl has over ten years of experience in academia, consulting, and industry, where he has worked in cross-functional teams of scientists and engineers to develop novel algorithms and innovative technologies to address challenges in water resources management.

Karl’s research focus is around climate resilient water resources management. He leverages approaches from artificial intelligence and systems thinking to develop sound science-based policies for small island developing states. 
•    Climate resilient water resources management
•    Clean technology for the circular economy
•    Artificial intelligence applications for climate resilience
•    Science-policy interface for improved IWRM
Research interests and achievements Karl's work in computational water resources modelling and environmental engineering has been published in Environmental Engineering Science, Water Research, and Environmental Science & Technology. He has also served as a reviewer for several international water resources focussed journals.

Dr. Payne was awarded the Richard Ian Stessel Memorial Fellowship in Environmental Engineering at the University of South Florida (2015) and was inducted into the University of South Florida Sigma Xi Scientific Research Honor Society (2018) in recognition of his innovative research. Dr. Payne has developed the UWI Cave Hill groundwater model for Barbados, which describes the groundwater flow dynamics for the island and will be leverage for enhanced water resources management under climate change.
