Research Interests

Ate Visser is a research scientist with expertise in isotope hydrology. He received his PhD cum laude from Utrecht University (the Netherlands) in 2009 and his MS in physical geography from the University of Amsterdam in 2004. After one year at the Netherlands Geological Survey and the research institute Deltares, he joined LLNL as a postdoc in 2010. He currently works in the Nuclear and Chemical Sciences Division and manages the environmental Noble Gas Mass Spectrometry laboratory at LLNL.

Visser studies the sustainability of water resources by applying environmental tracers in a variety of hydrological systems to investigate sources, pathways, and travel times of water. He focuses on combining multiple environmental tracers to calculate water travel time distributions. His work involves developing new tracers for hydrological research and applying these tracers to urgent water resource questions.
