Biography

Dr. Munk is currently a Professor in the Department of Geological Sciences where she conducts research on the hydrogeochemistry of nutrients and elements across a broad spectrum of hydrologic and climate regimes from the subarctic of Alaska to the Andean Plateau. She teaches courses in geochemistry, environmental geochemistry, isotope geochemistry, earth resources, and field-based courses. 

Teaching Responsibilities

  • GEOL A361 Earth Resources and Society
  • GEOL A460/660 Environmental Geochemistry
  • GEL A465/665 Isotope Geochemistry
  • GEOL A480 Geologic Field Methods
  • GEOL A490/A690 Geology of Death Valley

Research Interests

Dr. Munk's research is focused on the hydrogeochemistry of natural waters, in particular water-rock interactions and how major and trace elements and isotopes can be used to understand geochemical weathering and elemental cycles. She is interested in solving environmental problems as well as developing novel geochemical exploration and solution tools. She has multiple funded projects that take her and her students to the field in Alaska (Northwest Arctic, Southcentral Alaska, and Gulf of Alaska), U.S. southwest (Nevada), the south (New Mexico and Texas), South America (Chile and Argentina), and the Caribbean (Trinidad and Tobago). Her work is focused on problems associated with environmental geochemistry of mineralized terrains, the origin, transport and fate of nutrients in aquatic systems influenced by permafrost and glaciers, nutrient fluxes to the Gulf of Alaska, drinking water sources and quality, and the origin of lithium deposits and their connection to paleoclimate (brines and clays).  Dr. Munk also utilizes advanced geochemical and isotopic analyses coupled with laboratory experiments and geochemical modeling to test hypotheses centered around the field-based research questions. Recently she has become involved in climate solutions research centered around lithium as a sustainable resource for future energy needs.

She serves as Co-PI on the 5-yr $20M NSF Alaska EPSCoR “Fire and Ice” project. This project is focused on the impact of climate change on glacial recession and downstream shifts in nutrient, sediment and solute loads that are exported from land to the coast of the Gulf of Alaska (GoA) and how this impacts stakeholders who rely on coastal marine resources.

A recent highlight of the research that Dr. Munk and her colleague from UMASS-Amherst is that they were selected to conduct a high impact investigation on the sustainability of water use around lithium production funded by BMW and BASF: BMW Group commissions study on sustainable lithium extraction

Dr. Munk is actively seeking both graduate students and post-doctoral researchers to work on funded projects related to her research. The Munk lab welcomes people who are interested in working in a diverse group and who bring their own diversity to the team.
