BiographyDr. Munk is currently a Professor in the Department of Geological Sciences where she teaches courses in geochemistry, earth resources, and field methods. Her current research is focused on determining the hydrogeochemistry and origin of lithium brines and the role of high-latitude volcano weathering in the global carbon cycle.

Research InterestsDr. Munk's research is focused on the geochemistry of natural waters, in particular water-rock interactions and how major and trace elements and isotopes can be applied to understand geochemical weathering and elemental cycles. She is interested in solving environmental problems as well as developing novel geochemical exploration tools. She has applied the principles of geochemistry to diverse problems associated with mined and un-mined mineralized terrains and has investigated trace element geochemistry across a spectrum of environments from polar and high altitude deserts to temperate climates. Some of her recent projects are focused on the origin of lithium brines in South America and Nevada, groundwater quality and resources in Alaska, and the geochemical weathering of high latitude island arcs. Dr. Munk is actively seeking both graduate and undergraduate students to complete theses related to her research.
Dr. LeeAnn Munk and her colleagues form UMASS-Amherst and the USGS are developing a global model for Lithium-enriched brines. Why lithium? Lithium is a critical and strategic element that is required for lithium-ion batteries for which the utilities are far reaching from small electronic devices to hybrid/ electric vehicles as well as home batteries and robots. The global supply of lithium from brines is not well documented because it is an unconventional type of mineral deposit. Dr. Munk and her team are focused on the origin of these special lithium deposits and they currently study two of them, one in Nevada and one in Atacama Desert, Chile. The focus of the work is to document the hydrogeochemical processes responsible for the source(s), transport and accumulation of lithium in these closed-basin settings (Munk et al., 2016). With research support from industry and the NSF Munk and her team are becoming the leading experts in understanding where, when, why, and how these deposits form on a global scale.
