Hinkle investigates how trace metals common in natural systems (many of which are micronutrients and contaminants) and mineral structures are affected during biogeochemical cycling, with the goal of understanding how biogeochemical processes at the mineral-water interface affect the compositions of natural waters in present day and geologic systems. We study both abiotic and biotic factors contributing to changes in mineral structures and trace metal speciation and uptake. Our research combines inorganic chemistry, aqueous geochemistry, and biomineralization. We are currently conducting research projects on spring and groundwater geochemistry and the bioremediation of manganese by manganese oxidizing fungi, focusing on how our work intersects with environmental justice issues - in other words, how our research can be used to help improve water and soil quality in regions dealing with legacy contamination issues, develop new remediation strategies, and better understand geogenic and anthropogenic contamination risks in communities that rely on private water sources. Fungi are intimately linked to several geologic and environmental processes, such as element cycling, mineral formation and dissolution, rock weathering, soil formation, and the mobility of trace metals. We use wet chemistry techniques and bulk characterization methods, such as X-ray diffraction, Fourier transform infrared spectroscopy, and synchrotron-based X-ray absorption spectroscopy, in our research. https://images.squarespace-cdn.com/content/v1/576d87ae579fb384ed69b2af/1749060822988-UO72HSGSLVS6IQSPJSYR/JandK2025.jpg Home Congrats to all the EEG 2025 graduates, especially these two wundergrads from the Env Geochem Lab - Jorge and Kylie! https://images.squarespace-cdn.com/content/v1/576d87ae579fb384ed69b2af/1749060661501-JIHHATEQ7CLR9NPFNXBG/Ling+et+al.JPG Home New paper on Mn oxides forming in a passive coal mine remediation site in Appalachia out with Flo Ling (Le Salle), Jeff Post (Smithsonian NMNH), Eugene Ilton (PNL), and Peter Heaney (Penn State)! https://images.squarespace-cdn.com/content/v1/576d87ae579fb384ed69b2af/1724692459686-474342YH4JAGAKQ24JOO/AMD.jpg Home - Excited to announce our new NSF grant, collaborating with U of Pittsburgh professors Dr. Rosemary Capo and Dr. Brian Stewart on REE binding to Mn oxides in AMD! https://images.squarespace-cdn.com/content/v1/576d87ae579fb384ed69b2af/1715616983007-XJ32TBSD6QY95N3RQAPL/Mn+in+Shen+Valley+Sketch.PNG Home - New paper out with an awesome team of folks including wundergrads from the Keck Geology Consortium! https://images.squarespace-cdn.com/content/v1/576d87ae579fb384ed69b2af/1715615168285-IDZ0F8VFEY85FZL8WPG9/Hinkle+EGAH.PNG Home - New paper out with an awesome team of folks including wundergrads from the Keck Geology Consortium! https://images.squarespace-cdn.com/content/v1/576d87ae579fb384ed69b2af/1677729776031-D7QI2D1RSGWQJYU6D5UE/mchakraborty.jpg Home - Congratulations to postdoc Dr. Madhumita Chakraborty on starting her new tenure track position here in EEG at W&L Fall 2024! https://images.squarespace-cdn.com/content/v1/576d87ae579fb384ed69b2af/1749060967346-PJJMKU8WJ4LYQLYYPLNB/SE+GSA1.jpg Home Hinkle Env Geochem Group wundergrads ROCKED it at both Southeast GSA in Harrisonburg, VA and GSA in Anaheim, CA in 2024-2025 academic year!
