Prof. Andrew Martin is a researcher and teacher in energy technology with three decades of experience. Topics of interest include biomass, membrane distillation, polygeneration, and solar energy -- all of which play critical roles in sustainable development. These topics feature in a wide range of applied research projects in various contexts: from large-scale cogeneration to decentralized renewables-based polygeneration in rural locations; and for water purification and industrial wastewater treatment through waste heat-driven membrane distillation. Prof. Martin uses experimental studies, pilot plant trials, and simulations (component and thermodynamic systems analyses) to achieve research findings of relevance to industry and society.
