Chemistry & Biochemistry Faculty Publications
During the Asian summer monsoon season, pollutants from the lower troposphere are transported through deep convection to the upper troposphere and lower stratosphere. Surface pollutants such as CO are transported upward and trapped in the anticyclone during this unique atmospheric phenomenon. Associated with the anticyclone is a layer of enhanced aerosols located near the tropopause often referred to as the Asian tropopause aerosol layer (ATAL). The chemical and physical properties of aerosols in the ATAL are not yet fully understood as direct observations of the aerosols are limited. The Atmospheric Chemistry Experiment (ACE) is a satellite mission that provides high-resolution …

Plastic Gerontologies: Epigenetic Clocks As Instruments Of The Profitable Medicalization Of Aging, Hans T. Purisch
Theses and Dissertations--Geography
Epigenetic clocks are algorithms that use epigenetic biomarkers of aging to calculate an organism’s ‘biological age.’ Through discursive analysis of commercially available epigenetic clock marketing materials, scientific articles, and interviews with actors in the longevity biotechnology industry, this study examines the commercialization of epigenetic clocks in the form of consumer test-kits. The study argues that longevity biotechnology companies leverage the malleable and fluid qualities of epigenetic markers of biological age to extend the domains of profitable therapies. It shows that epigenetic clock companies market the dynamic qualities of epigenetic biological age measurements to redefine health around the project of optimizing …

Lust, Labor, & Legitimacy: Visibility And Precarity In Platformed Sex Work, Sable J. Augustyn
Theses and Dissertations--Geography
This thesis examines the labor of platformed sex workers, positioning their experiences as a site for understanding the entanglement of multiple intersecting economies. Through qualitative interviews, it explores how sex workers navigate platform infrastructures, manage audience engagement, and contend with visibility as both an economic necessity and a site of risk. Drawing on theories of emotional labor, visibility labor, and platform governance, the project highlights how sex work on digital platforms is shaped by overlapping systems of economic extraction, technological constraint, and cultural regulation. Platformed sex work emerges here as a layered and context-specific practice—embedded within creator ecologies, attraction economies, …

Woke-Lahoma: Anti-Trans Ideology On The Frontlines, Sarah H. Fogel
Theses and Dissertations--Geography
The past decade (2015-2025) of American politics has been marked by a sharp rise in anti-trans politics. Indeed, during this period, anti-trans rhetoric and legislation have become central to American conservative politics more broadly. As the Republican party under Donald Trump works daily to remake the federal government in its image, studying the recent past of Republican-controlled states like Oklahoma offers a window into the future of anti-trans politics at the national scale. This thesis uses a mix of discourse analysis of anti-trans media and participant observation at 2SLGBTQ+ Pride events to analyze the ideological underpinnings of the present-day anti-trans …

Spatializing The Tax Code: Using Property Records To Locate The Fiscal Face Of Rentiership, Michael J. Mccanless
Theses and Dissertations--Geography
This dissertation analyzes how the tax code shapes housing financialization in mid-sized US cities. Employing a mixed-methods approach that integrates critical computational analysis with qualitative fieldwork in Memphis, I examine the role of public rent-seeking in shaping housing financialization in U.S. cities. The first article analyzes the property tax appeal strategies of corporate landlords and their implications for public revenues and municipal budgets. The second article explores how the IRS 1031 exchange provision—which allows for capital gains deferrals when the proceeds of a property sale are reinvested in a ‘like-kind’ property—facilitates the movement of capital from high-cost coastal markets into …

Making Slums Legible, Visible And Calculable: Geospatial Technologies And The Governance Of Urban Land In Mumbai, Sanjana Krishnan
Theses and Dissertations--Geography
This dissertation examines how geospatial technologies are used to make slums in Mumbai legible, calculable, and hypervisible, and how these practices reshape urban land governance. It situates mapping, remote sensing, and algorithmic systems within their political-economic contexts, showing how technologies intending to see the city often function as instruments of dispossession. The research has three interconnected empirical chapters. The first empirical chapter traces the history of slum mapping in Mumbai, from their absences in early development plans to their selective hypervisibility under the contemporary governance regimes. Using critical cartographic methods, it highlights how novel technologies such as remote sensing, biometric …

Land Rematriation: Utilizing The National Register Of Historic Places And Developing Tribal Homeland Territories For The Restoration Of Historic Landscapes And Sovereignty, Robert E. Hazen
Dissertations, Master's Theses and Master's Reports
Land rematriation and cultural revitalization are crucial to addressing the ongoing impacts of settler colonialism on Indigenous communities, particularly for the Lac Vieux Desert Band of Lake Superior Chippewa. The National Register of Historic Places and federal recognition processes have traditionally marginalized Indigenous practices and land claims, yet, as I argue in this thesis, they hold potential for reappropriation in support of sovereignty and heritage. This thesis argues that integrating Indigenous methodologies, geospatial research, and archival analyses can forge a path toward effective land rematriation efforts. My findings reveal culturally significant sites connected to the historic village of Getegitigaaning, helping …

Evaluating Uas & Als Lidar’S Ability To Detect Understory Shrubs In Rhode Island Forests, Noah Henkenius
Open Access Master's Theses
Understory shrubs provide important habitat for wildlife and assist with nutrient cycling in forests. The use of remote sensing to map shrubs in forest understories is challenging due to the obscuring effect of the forest overstory. We tested the effectiveness of leaf-off aerial LiDAR and uncrewed aerial system (UAS) (point densities of 8+ pts/m2 and 250+ pts/m2, respectively) to map shrub cover in a mixed deciduous forest in Rhode Island (USA). We used a terrestrial laser scanner (TLS) and field vegetation surveys to provide validation data. We found that UAS and aerial LiDAR had average omission errors …

Changes In Small Area Flow Accumulation And Watershed Creation In Fredericksburg, Virginia, Jacob P. Lohr
Research and Creativity Symposium
This study explores the application of watershed analysis tools—including the Flow Accumulation, Flow Direction, and Fill tools—on small-scale areas within the rapidly developing City of Fredericksburg. By applying these GIS tools to high-resolution LiDAR-derived Digital Elevation Models (DEMs), the study examines water flow patterns before and after urban development. Results from two primary study sites demonstrate that, when properly utilized, these tools can effectively delineate small-scale hydrological changes from urban development. However, analysis of a third site reveals challenges associated with DEM cleaning. Particularly, the limitations of the Fill tool, highlighting the need for manual editing and further refinement for …

Endeavors: Mississippi State Undergraduate Research Journal
Abiotic and biotic forest disturbances can have many impacts to forest ecosystem services, including to forest water use. Studies on impacts to forest evapotranspiration have been conducted on the mountain pine beetle (Dendroctonus ponderosae) in western North America, but not on the southern pine beetle (Dendroctonus frontalis), which is a native pest of loblolly pine (Pinus taeda) and shortleaf pine (Pinus echinata), in the southeastern United States. Stressed pine trees produce pheromones that attract southern pine beetles and, with enough stressed trees, beetle populations can quickly grow to epidemic levels and attack healthy trees, which results in widespread tree mortality. …

Assessing High-Speed Rail (Hsr) Policy And Politics In Washington State: Avoiding The Mistakes Of The Past, Landen K. Hashimura
All Master's Theses
While international standard high-speed rail (HSR) has yet to be successfully completed in the US, there is a national interest in the topic, as evidenced by recent federal initiatives to research HSR across various corridors. The Cascadia Corridor has been identified as a region with high potential for HSR, leading to an ongoing study in the State of Washington. Given the tumultuous history of American HSR development, the Cascadia HSR initiative needs to avoid the mistakes of the past. Two major contributing factors to this failure to build HSR are uneven political support for HSR and poor policy frameworks. Despite …

As beavers are increasingly used in stream restoration, interest in their potential to mitigate stream degradation has grown. However, the impacts of beaver dams on stream temperature remain inconsistent across studies, often due to differences in spatial scale and methodology. We investigated summer thermal regimes at multiple spatial scales in three beaver-impacted streams within the Tualatin River Basin, Oregon, using fiber-optic distributed temperature sensing. Substantial variability in thermal regimes was observed among the three stream reaches and around individual beaver dams within each reach. This variability was primarily influenced by geomorphic changes in stream depth associated with beaver dams and …

Map Marker Accuracy: Evaluating Spatial Data Quality In A Simplified Mapping Survey, Christopher Sean Ghormley
Masters in GIS Practicum Reports
Collecting spatial information using maps is a recurring need in research and policy (Evers, 2020; Gottwald et al., 2016; Hitchins, 2018; Tang & Liu, 2016). Survey participants frequently abandon map-based surveys at the first mapping task (Poplin, 2015). In his survey of wildfire risk management personnel, Evers (2020) applied a simplified web-mapping interface that uses circles as the sole input geometry for all spatial representations. The current project examines an updated version of this web map. An anonymous survey gathered data from participants who completed six mapping exercises within Portland, Oregon, and provided feedback on the survey experience. A working …
