Research Group – Katharina Pfaff
Dr. Katharina Pfaff
Research Associate Professor
Department of Geology and Geological Engineering
Katharina is a mineralogist by training and obtained her MS degree in 2007 (Igneous Petrology), her PhD in 2010 (Economic Geology) and joined Mines in 2012. Katharina established and runs the MMC Facility. Katharina’s research combines mineralogy, geochemistry, thermodynamic modeling, and artificial intelligence and applies it to improve our understanding of igneous, metamorphic, and ore forming processes.
Current Group Members
Danny Schmidt is working on a Ph.D. project developing a workflow to better understand the subsurface and advance critical mineral exploration and assessment. Co-registered magnetic susceptibility, geochemistry and hyperspectral data on core are used to inform geophysical data analysis and to advance our understanding of our domestic critical mineral endowment. His research is funded by the Center to Advance the Science of Exploration to Reclamation in Mining.
Isaac is a Ph.D. student at Mines, working alongside professors at the Universidad Nacional de San Agustin in Arequipa, Peru. His research involves studying the hydrogeochemical signatures of ore deposits and anthropogenic activity in major watersheds supplying freshwater to Arequipa. His professional experience includes working as a Mining Geo and in a Greenfields exploration project. His work is supported through the Center for Mining Sustainability.
Matthew is a graduate student working on estimating the carbonation potential of the Caribou-Cross mining area using cutting-edge X-ray fluorescence core scanning technology and normative mineralogy in conjunction with kinetic and thermodynamic considerations. His research is funded by the Center to Advance the Science of Exploration to Reclamation in Mining.
Filip is a second-year M.S. student and lab assistant in the MMC Facility. His research focuses on sulfide recrystallization textures and critical mineral occurrence in a polymetallic VMS deposit in Quebec.
Filip’s Ph.D. research will focus on understanding the occurrence and sequestration of critical minerals contained within a wide variety of mineral deposits and deposit types (VMS, SEDEX, etc.), and the application of cutting-edge microanalytical techniques to these questions and others in economic geology and mineralogy. His research is funded by the Center to Advance the Science of Exploration to Reclamation in Mining. Outside the lab he enjoys skiing, hiking, and photography.
Lindsey is a second-year master’s student. Her research is on a number of polymetallic VMS deposits from the Noranda Camp in Quebec, looking at the metal endowment throughout the district.
Joseph is a first-year M.S. student and works as a lab assistant in the MMC Facility. He is interested in doing research related to economic geology and mineralogy of metal deposits. Outside of the classroom, he enjoys drawing, writing, and exploring the outdoors!
Zaid Al Attar
Zaid is a graduate student developing a workflow to acquire co-registered UAV-based and laboratory-based hyperspectral data and to interpret these datasets in a fused manner. This study will improve our understanding and ability to interpret UAV- and laboratory-based hyperspectral surveys in the context of mineral exploration.
Pablo Chang Huang
Pablo is an undergraduate Senior in Geophysical Engineering who works as a lab assistant in the MMC Facility. He is also working on research that uses a machine learning algorithm to automate masking of hyperspectral data to exclude data from core boxes, wooden blocks, and broken material, for hyperspectral core imaging. His research is funded by the Center to Advance the Science of Exploration to Reclamation in Mining.
