Dr. Andres Payo is a distinguished Coastal Geomorphologist affiliated with the British Geological Survey. Internationally recognized for his expertise in coastal geoscience, Andres specializes in quantitative geomorphology as applied to long-term coastal protection strategies against flooding and erosion, focusing on decadal and longer time scales. Employing a systems-of-systems approach, he is dedicated to leveraging long-term analytical capacity to mitigate the risk of maladaptation in the design and management of enduring coastal infrastructure systems.

Collaborating with both academic and non-academic partners, Andres has pioneered the development of several quantitative tools crucial for supporting spatial planning initiatives among coastal stakeholders. For instance, his groundbreaking systems approach to addressing soil salinization in low-lying agricultural areas has been embraced by the government of Bangladesh as a cornerstone in exploring diverse interventions aimed at poverty alleviation.

Additionally, Andres has significantly contributed to advancing the sediment transport module within the Cross Shore model, a pivotal tool utilized by the US Army Corps of Engineers for assessing beach and dune dynamics during storm events and subsequent recovery phases.

Furthermore, as the lead developer of the Coastal Modelling Environment (CoastalME) software, Andres has engineered a sophisticated platform integrating sub-bottom properties and highly detailed digital terrain models. This innovative tool empowers comprehensive assessments of coastal flooding and erosion risks across timescales spanning from decades to centuries.

With an unwavering commitment to excellence, Andres actively seeks and welcomes collaborations with esteemed academic institutions, leading consultants, and government agencies both in the UK and abroad.
