Staff profiles
Valerie StuckerWater and Ice :Laboratories Manager
Biography
Val is an analytical geochemist and the Earth and Environmental Science Laboratories Manager at GNS Science. She is passionate about method development and using analytical chemistry to solve scientific questions, with particular interests in hydrothermal systems, environmental remediation, volcanic monitoring and climate change. Since 2013, she has been investigating the chemistry and evolution of hydrothermal fluids at submarine volcanoes along the Kermadec arc and sublacustrine lakes in New Zealand. She earned a Ph.D. in geochemistry from the Colorado School of Mines where she studied the impacts of biostimulation on groundwater uranium and remediation strategies for the inadvertent release of arsenic during sulfate reduction.
