Sea mammals are central to life for coastal Arctic Indigenous communities and continue to provide a significant part of subsistence resources. The harpoon piece is in the collection of the MU Museum of Anthropology.
(Right photo) Alaska Native communities highly value animals, nonhuman kin, who give their lives to sustain humans. For this reason, all parts of the animals are used, and nothing is wasted. Antlers, for example, were expertly carved into armor plates that protected the wearer’s upper body. The armor set is from the Kukulik archaeological site on St. Lawrence Island, Alaska, and it is in the Corrington collection of the MU Museum of Anthropology.
Bergstralh's research focuses on the establishment and maintenance of epithelial tissue architecture. Epithelia are the most common tissue type in animals. They can be found at organ boundaries, where they perform functions including absorption (the intestine), secretion (glands), filtration (kidneys), and gas exchange (the lungs). Epithelia are typically organized into sheets of cells that are one-cell thick. Bergstralh's lab aims to understand how these sheets develop.

Digital 3D models of Indigenous ancestral heritage are now standard practice in heritage preservation, but our understanding of how they are viewed by Arctic Indigenous communities is still lacking. Csoba DeHass’ project will bridge this gap by examining Indigenous perceptions and use of digital 3D models through the first systematic 3D modeling and digital repatriation of Alaska Native cultural heritage from the Bering Strait region. The project will provide training for undergraduate researchers as well as develop a plan for providing Indigenous communities across the country access to distant museum collections.
Nanopore stochastic sensing has attracted substanital interest as a label-free technique to measure single molecules by taking advantage of the ionic current modulations produced by the movement of target analytes in a single nano-scale sized pore. A major bottleneck of utilizing nanopore sensors for practical applications is the rapid transport of target analytes through the pore since current recording techniques do not always accurately detect these rapid events. Guan's research efforts advance nanopore technology as a versatile tool for exploring various new applications, especially in medical diagnosis, homeland security, pharmaceutical screening, and environmental monitoring.
Handa's research lab aims to enhance discovery through fundamental science and train students to create a future workforce specializing in safer organic syntheses, catalysis, and drug discovery for a sustainable environment and health. This mission also promotes diversity and inclusion through students' direct collaboration with the pharmaceutical industry.
Hennes' research in the Social Cognition of Social Change (SCSC) lab focuses on cognitive and motivated biases in information processing and person perception, particularly in the context of contemporary social issues such as environmental sustainability, and racial and gender inequality. Much of this research examines how concern for the maintenance of social stability and preferences for restorative vs. progressive change influence cognitive processes.
Hutchins' research focuses on designing and syntheszing materials by using supramolecular chemistry strategies to achieve desirable properties. Her group focuses on controlling the response of materials to changes in temperatures, improving properties and processes in pharmaceuticals, and design of materials that capture rare earth elements.
Lane's research focuses on the precise measurement and modeling of dynamic processes critical for conducting empirical research that matches data to theory, and that effectively identifies momentary opportunities for clinical intervention. He develops systems methods for examining and intervening on dynamic phenomena with a focus on emotion, interpersonal, and health-related regulatory processes.

Meng’s research focuses on semiconductor crystal growth for optoelectronic device applications and on characterization of materials towards a structure-based understanding of functional properties. There are several central research themes: novel ferroelectrics based on alloys of aluminum nitride, dielectric breakdown and resistive switching, and transmission electron microscopy and other structural characterization techniques.

Park studies the impact of dramatically evolving information technology on society. Specifically, he examines how the improved information environments lead to increasingly stricter human rights standards and changing expectations in our society.
Pesko's research focuses on identifying the casual effects of health policy changes using survey and administrative data sources. His projects include e-cigarette policies, paid sick leave mandates, and private insurance mandates for hearing aids and cancer prevention/early detection services.
Rubin's research employs tools from evolutionary game theory and network science to provide a picture of how aspects of social identity uncovers hidden roadblocks for marginalized groups, suggests potential remedies, and demonstrates when policies focused on efficiency in science would not only further entrench (or even amplify) current injustices, but backfire, ultimately impeding scientific progress.
Xu's research seeks to understand why sexual reproduction and meiotic recombination are dominant in eukaryotic species despite their heavy evolutionary costs. To address this question, his research uses the microcrustacean Daphnia as a model system to investigate the causes and consequences of obligately asexual reproduction and the evolutionary forces driving the variation of meiotic recombination rate at different biological scales (e.g., between populations/species).
Zeng researches the fundamental interfacial phenomena at electrode interfaces for the development of next generation detection technologies, in situ detection and quantification of molecules and species of chemical and biological significance with high sensitivity and specificity at high temporal and/or spatial resolution for a broad range of applications including health, environment, and energy.
