Vaughan Voller

Professor Vaughan Voller is a faculty member in the Department of Civil, Environmental, and Geo-Engineering at the University of Minnesota, where he conducts research at the St. Anthony Falls Laboratory. His work focuses on developing numerical and analytical techniques for problems in geophysics and heat transfer, with particular emphasis on situations involving moving boundaries and free surfaces.

Professor Voller's educational background spans several decades of research in computational methods for geophysical systems. His expertise includes modeling crystal growth in undercooled melts, shoreline advance into sedimentary basins, unsaturated drainage, and particle-based solutions to Stefan problems. His research bridges theoretical mathematical approaches with practical geophysical applications, particularly in understanding shoreline evolution, sediment transport processes, and phase change phenomena.

His recent publications (2021-2025) demonstrate a strong focus on coastal hydrogeology, deltaic systems evolution under sea-level changes, anomalous diffusion phenomena, and moving boundary problems in geophysical contexts. The research shows increasing integration of fractional calculus methods to address complex transport phenomena that don't follow classical diffusion models.

Professor Voller has secured significant research funding for projects including:

• Field Investigation of Hydrologic and Hydraulic Characteristics of Effective Sea Lamprey Barriers (2025-2027)
• HYDROLOGIC AND HYDRAULIC CHARACTERISTICS OF EFFECTIVE SEA LAMPREY BARRIERS (2022-2024)
• Collaborative Research on Sea-Level Change, Sediment Transport and Geomorphology (2019-2024)
• Physical and numerical modeling of progradation of segregating tailing beaches (2018-2022)

He teaches CE 8022: Numerical Methods for Moving Boundary Problems, emphasizing practical implementation of numerical methods including Control Volume Finite Element Method solutions. His research group maintains an active agenda with consistent publication output, reflecting his sustained contribution to the field since the 1980s.
