2025-2027 Cohort (Year 2)

Anna is a new faculty member at the Water and Environmental Research Center at UAF. Originally from a small Italian mountain village, she earned her PhD from ETH Zurich, studying sediment dynamics in a glacierized Alpine catchment. Her doctoral work revealed the strong link between climate, erosion, and sediment transport. Before UAF, she was a researcher at ETH Zurich, developing hydrological models in Nepal, Africa, and Southeast Asia, focusing on extreme climate events. She first connected with Alaska in 2019 during a research assignment at the Alaska Climate Research Center, a period during which she and her family fell in love with the state and aspired to return.

Her research focuses on the complex interplay between climate, water, and sediment fluxes in river systems. Ongoing changes in Alaska—including intense precipitation, permafrost thaw, and glacier melt—suggest increased erosion and river sediment loads. Similar trends have been observed in other cold regions, with potential significant impacts on ecosystems, fish habitats, and infrastructure. By integrating field data, remote sensing, and advanced modeling, Anna aims to develop predictive models of hydrology and sediment transport in rapidly changing Arctic and sub-Arctic rivers.

She is dedicated to mentoring and supporting students through advising graduate students, teaching graduate-level courses, and leading workshops and other educational activities.

More about Anna Costa
I am a postdoctoral research fellow working at the Geophysical Institute at the University of Alaska Fairbanks. I joined UAF as a graduate student in the sea ice research group in 2019 and earned my Ph.D. in Geophysics with a concentration in snow, ice, and permafrost geophysics in 2025. My doctoral research focused on better understanding sea ice deformation at scales of meters to kilometers using combined radar remote sensing and field observations. During this work, I was fortunate to participate in fieldwork at drifting camps on the Beaufort Sea, as well as in the Alaskan communities of Utqiaġvik and Nome.

My current research builds on this doctoral work, aiming to continue to better understand sea ice deformation at intermediate spatial scales. I am particularly interested in landfast sea ice, the area of stationary ice contiguous with the coastline that is integral to wintertime subsistence activities and travel in many Arctic coastal communities.
Amy Holt joined the Alaska Coastal Rainforest Center (ACRC) as a postdoctoral fellow in 2025. Prior to that, she held a postdoctoral position at Florida State University, where she also earned her Ph.D. and M.Sc. To date, her research has focused on understanding the sources of organic carbon in glacier ecosystems and how glacier decline, both in southeast Alaska and globally, influences stream biogeochemistry and watershed carbon cycling.

More broadly, Amy is interested in projects assessing the role of organic carbon in a range of aquatic and polar environments from the world’s oceans to coastal waters of British Columbia and southeast Alaska, to peatlands in the U.K, permafrost in the Arctic and lakes in the Antarctic. Much of this research has an anthropogenic element and works to gain a mechanistic understanding of how climate change particularly within the cryosphere continues to impact the sources, fate and cycling of organic carbon at watershed and global scales. To do this, Amy uses a range of analytical techniques including bioincubation experiments, molecular, biomarker and isotopic analyses.

Through the Arctic Leadership Initiative Early Career Fellowship, Amy continues to examine how cryospheric change, particularly glacier retreat, shapes the delivery and composition of organic carbon in freshwater and coastal ecosystems. Her work also assesses the role of glacier derived carbon, including organic carbon and methane, in stream food webs and watershed biogeochemistry.

Outside of research, Amy enjoys yoga, hiking, cooking, and, whenever possible, skiing and climbing.
Dr. Colin Maher is a researcher at the Environment and Natural Resources Institute at the University of Alaska Anchorage and an ORISE Fellow through the USDA Forest Service. Colin’s general research interests are understanding the ecology of trees and forests in boreal and mountain environments, including arctic and alpine treelines—the northern and elevational limits of trees. In his previous position as a postdoctoral researcher at UAA, Colin helped initiate a field-based study of treelines at 19 remote sites across Alaska’s Brooks Range. One outcome of this research was the discovery of a link between treeline advance and tree-ring growth with the decline of autumn sea ice in the Chukchi and Beaufort Seas. His current research seeks to disentangle this link by testing competing hypotheses of what could cause it: 1) decreased sea ice could lead to more local-source precipitation as snow, which insulates soils in winter. This benefits soil microbes, which in turn can increase soil nutrient availability and increase tree growth. 2) More simply, increases in temperature may be affecting sea ice and tree-rings separately but in ways that result in similar trends.

Megan Behnke was born and raised here in Lingít Aaní. She first joined UAS as a stream chemistry technician in 2016 with the Alaska Coastal Rainforest Center, and returned in 2022 to serve as postdoctoral fellow through the Coastal Rainforest Margins Research Network and the Alaska Climate Adaptation Science Center. In between she received her MS and PhD from Florida State University, studying what happens when warming temperatures release organic carbon that has been locked away in permafrost, glaciers, and wetland soils in both coastal temperate rainforests and around the pan-Arctic with the Arctic Great Rivers Observatory. Megan uses a combination of ultrahigh resolution mass spectrometry and elemental and isotopic ratios to explore how the sources, processing, and fates of organic matter are changing due to climate change and associated shifts in land use and land cover.

Megan's current research interests include understanding how cryospheric warming (i.e. glacial melt and permafrost thaw) is changing the type and delivery of organic matter to streams and to the nearshore environment and the role human actions (such as fossil fuel burning) have on organic matter cycling. She is also interested in understanding the role of trees in delivering dissolved organic matter to forest floors, stream systems, and the nearshore environment. In addition to research, Megan spends her time paddling, skiing, climbing, gardening, reading (particularly science fiction) and bushwhacking around the forest trying to find her dog.

Memphis is a postdoctoral fellow at UAA researching sustainable biomining of critical minerals. Her work aims to characterize microbial interactions with rare earth elements and harness these interactions to develop more environmentally friendly methods for rare earth element extraction and separation. Her previous work spanned topics on the nitrogen cycle, trace metal biogeochemistry, microbial ecology, water and soil quality, and human impacts on the environment. Prior to graduate school, she spent 3 years as a research technician and lab manager in the Bone Marrow Transplant and Cellular Therapies Division at the Children's Hospital of Pittsburgh.

I am a new postdoc at the International Arctic Research center at the University of Alaska Fairbanks. Currently, I am funded through the Arctic-Yukon-Kuskokwim Sustainable Salmon Initiative. Environmental DNA (eDNA) is genetic material shed by organisms in their natural environment. It is possible to use eDNA to detect species of interest in ecosystems. I use environmental DNA techniques to both (1) study the declining salmon runs that have caused severe hardship in subsistence communities within the Arctic-Yukon-Kuskokwim (AYK) region and (2) quantify clam abundance that has been a hardship to the intertribal Chugach Regional Resources Commission and scientists at the Alutiiq Pride Marine Research Institute. I will use a previously published quantitative polymerase chain reaction (qPCR) assay to detect salmon. I plan to develop an assay for clam eRNA.

The detection of eDNA, using qPCR, needs to be statistically validated. I will fit statistical models to predict daily salmon passage using eDNA concentrations. The outcomes of the research aim to inform tribal members of salmon abundance in the Kuskokwim River Basin. For quantification of eRNA, experiments will be run at the Alutiiq Pride Marine Research Institute to quantify and differentiate between larvae, juveniles and adults.
