Dr. Emily Eidam, PI

Associate professor

I’m a sedimentologist / marine geologist with background in Civil Engineering (BS, UAA), Geology (BS, UAA), and Oceanography (MS and PhD, UW). I grew up in Eagle River, Alaska (near Anchorage) in a landscape sculpted by glaciers and interesting sedimentary processes. I enjoy working in “process sedimentology” because it combines elements of fluid dynamics, sedimentology, and oceanography and allows us to explore how sediments move through a system over human timescales, and how they ultimately contribute to the geologic record. This work synthesizes data from diverse tools (e.g., oceanographic sensors, isotope geochronology, remote sensing) and helps us better predict where sediment is going and under what conditions—with relevance to models of coastal evolution, nutrient and contaminant transport, and geologic resource formation.

Dr. Molly Keogh, postdoctoral scholar
NSF Postdoctoral fellow, office of polar programs

Molly is a National Science Foundation OPP postdoctoral scholar with PhD in Earth and Environmental Sciences from Tulane University and BS in Geology from the University of Oregon. Molly specializes in studying coastal sediment dynamics, including how sediment moves through coastal systems, and what it means for resilience of estuaries, deltas, and other low-lying coastal environments. Fun fact: her graduate work is featured in the documentary film “Last Call for the Bayou” (Episode 2, “Mud, Sweat, and Fears”).

Dr. Hannah Glover
Research Scientist, OSU Civil & Construction Engineering

Hannah is a research scientist based in Civil & Construction Engineering and CEOAS. She earned her MS and PhD degrees in Oceanography from the University of Washington and studies sediment transport, DAS systems, marine mapping, and diverse other topics.

Grace Meyer, Laboratory Technician
MS from CEOAS OEAS program

Grace is a laboratory technician in both the Fehrenbacher and Eidam labs and specializes in data processing, sample analysis, and sensor building. She completed her MS in Ocean, Earth, and Atmospheric Science at OSU and developed a small-sample analysis method on a Dual-Inlet Isotope Ratio Mass Spectrometer. 

Adrian Heath, MS student
Ocean, Earth, & Atmospheric Sciences Program

Adrian joined the lab in summer 2022 to study sediment transport processes in the Alaskan Beaufort Sea. He has a BS in Geology from Colgate where he studied hypersaline soils from the McMurdo Dry Valleys of Antarctica as part of an undergraduate research project. He has since worked as geologist for an environmental consulting firm in New York City, professional brewer, and ski and kayak instructor at Jackson Hole before moving to Corvallis.

Emily An, MS student
Ocean, Earth, & Atmospheric Sciences Program

Emily is working on suspended sediment distribution in ice fjords of western Greenland as a part of the TERMINUS project. She has a B.S. in Marine Sciences and minors in Geology and Wildlife Ecology & Conservation from UF. Her undergraduate research used strontium isotopes from glacial and deglacial stream waters of southwest Greenland to track the progression of sediment and rock weathering with ice sheet retreat. Between her degree programs she worked on biodynamic farms, assisted on an Arctic research cruise, and instructed field conservation ecology courses on Maui. 

Eden Krolopp, MS student
Ocean, Earth, & Atmospheric Sciences Program

Eden has experience in hydrologic data collection and analysis. She completed a BS in Geology and Environmental Policy from the University of Puget Sound and a Graduate Certificate in River-Coastal Science and Engineering from Tulane University.  As part of the Eidam Lab, she works with the Beaufort Lagoon Ecosystems LTER team studying coastal sediment dynamics in Northern Alaska.

Sean Finney, MS student
Geography and Geospatial Science Program

Sean is a GIS professional who is conducting research on streamflow and sediment export in the Oregon Coast Range in fulfillment of his degree.

Riley Smith
Undergraduate research assistant

Riley is a laboratory assistant pursuing a BS in both Oceanography and Electrical and Computer Engineering and plans to work in marine technology. She is focusing on building and developing turbidity sensors and analyzing multibeam data on keel scours from the Alaskan Beaufort Shelf.

Anika Lechner Armitage
undergraduate research assistant (URSA program)

Anika is working on a BS in environmental science with a concentration in applied ecology and a GIS certificate. She will be analyzing a sediment core from Yaquina Bay in coastal Oregon.

Tess Hoffman
undergraduate research assistant (URSA program)

Tess is double-majoring in Oceanography and Integrated Science Education, and will be working on polar sediment core analyses. She plans to teach in the environmental education sphere after graduating.
