He is an assistant professor in the Department of Earth and Environmental Sciences at the University of Illinois – Chicago. He received a BA in Environmental Science from Hampshire College (Amherst\, MA)\, a Ph.D. in Environmental Science\, Policy\, and Management at the University of California\, Berkeley\, and conducted NASA and NSF-funded postdoctoral work at the University of Minnesota. He draws on diverse research experiences\, including investigating nuclear waste disposal at Lawrence Livermore National Lab\, community-based soil remediation on urban farms in California\, cycling of limiting nutrients in Earth’s oceans\, and habitability of extraterrestrial ocean worlds\, to determine how the chemical form of contaminants and nutrients explains their landscape-scale transport. \nIron (Fe) is a necessary but often limiting nutrient for life on Earth. Supply by sediments and dust deposition are typically considered the main sources of iron to Earth’s oceans\, but recent advances suggest hydrothermal vents might also be an important source of bio-essential iron over the length scales of ocean basins. Dissolved iron concentrations in hydrothermal fluids are a million times those of surrounding ocean water. Most iron (>90%) precipitates close to vent sources\, but the international GEOTRACES program revealed signatures of hydrothermally-derived iron transported across deep ocean basins worldwide. However\, it remains unclear how this iron persists in the water column rather than being sequestered into sinking particles. Critical processes constraining the export of hydrothermal iron to open ocean waters occur within the first ~100 km of plume evolution. \nTo this end\, we compare hydrothermal plume particulate matter collected from the first 100 km of plumes in the low-sulfur\, high-oxygen Rainbow vent system (Mid Atlantic Ridge) and high-sulfur\, low-oxygen Endeavour vent field (Juan de Fuca Ridge\, North Pacific). We use a novel multimodal approach combining bulk to nano-scale synchrotron-based methods and electron microscopy. We show that plume chemistry affects the mineral phase of iron\, with iron(II) phases persisting longer in the high-sulfur\, low-oxygen Endeavour plume. Yet suspended particle morphology–nanoparticulate iron embedded in carbon matrices–is similar in both plumes. We explore carbon matrix chemistry and potential links to vent microbial communities. Co-located iron and carbon within marine particles drives export of iron from hydrothermal vents to open ocean waters and is a signature of nutrient-rich oceanic hydrothermal activity globally. \n\nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom. Most talks will involve the theme of Emerging Contaminants in Aquatic Environments. Snacks will be available prior to the talk.

She earned her PhD in Environmental Engineering at the University of California at Berkeley in 2002. She joined the faculty in the Civil and Environmental Engineering Department at the University of Wisconsin Madison in 2003 and became cross-appointed with the Bacteriology Department in 2008. She was promoted to Associate Professor with tenure in 2008 and professor in 2013. Her research interests span multiple dimensions of the “water microbiome” including wastewater treatment and freshwater quality. She has a special interest in wastewater treatment bacteria that sequester phosphorus using an enigmatic physiology. She is heavily invested in the North Temperate Lakes Long Term Ecological Research site and directs the NTL Microbial Observatory. Finally\, she is passionate about future faculty professional development and has served as Co-Faculty Director of the Delta Program in Research\, Teaching\, and Learning at UW-Madison since 2011. She was elected as a fellow in the American Academy of Microbiology in 2018. \n\n \nFreshwater lake bacterial populations are dynamic. Ecological forces alter their community composition and evolutionary processes shape their genomes. In this presentation\, recent findings made possible through a 20-year time series of metagenomic data generated from Lake Mendota\, Madison\, WI will be shared. This study used genome-resolved approaches to examine how population-level diversity changes over time scales from weeks to decades. Results show that aquatic invasive species are restructuring the lake foodweb\, with cascading effects on lake bacteria. Climate change is impacting the populations\, through variation in precipitation patterns and intensity. This unprecedented dataset allows us to view lake bacteria through a genomics lens\, revealing the interacting forces of evolution and ecological drivers. \n\n  \n  \nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom.

She received her B.S. in Chemistry from The College of William and Mary in Virginia and her Ph.D. in Marine Chemistry and Geochemistry from the Massachusetts Institute of Technology/Woods Hole Oceanographic Institution Joint Program in Oceanography and Ocean Engineering. Her research group studies carbon cycling in lake\, river\, and ocean water columns across daily to decadal scales. This includes work on lake acidification and alkalinity trends and studies of organic matter in aquatic systems\, including that new anthropogenic organic matter\, plastics. Support for her work has come from the US National Science Foundation\, the Minnesota Pollution Control Agency\, the State of Minnesota Environmental and Natural Resources Trust Fund\, Minnesota Sea Grant\, the ACS Petroleum Research Fund\, and the US National Park System. \n \n\nHumans have impacted large-lake carbon cycles in several ways\, including shifting atmospheric exchanges of inorganic carbon\, the effects of erosion and chemical weathering\, inputs of nutrients\, and inputs of anthropogenic carbon species such as microplastics. This talk will discuss anthropogenic impacts on Lake Superior carbon cycling\, with a focus on microplastics and inorganic carbon inputs. \nThe Spring 2025 Freshwater Colloquium series will be held in the GLRF Ballroom.
