- This project explores novel approaches to image segmentation using U-Net, leveraging superpixels to enhance accuracy. The first part investigates augmenting standard image inputs by encoding and integrating superpixel information, including an extension that reintroduces this information throughout the encoder. While results show that these methods can offer consistent improvements over the baseline, the gains are modest and suggest room for further optimization. The second part introduces a hybrid data structure, the Superpixel-Integrated Grid (SIGrid), which embeds superpixel boundary, shape, and color descriptors into a regular n × n grid. SIGrid enables more efficient training on smaller architectures while achieving noticeably higher segmentation accuracy, highlighting its potential as a lightweight and effective input representation.

- Large impoundment dams have well-documented impacts on hydrologic and geomorphicfunction. Numerous tools and metrics have been developed over time to characterize theseimpacts, but they remain disparate, are often applied in a small number of studies, and rarelyapplied in concert with each other. Utilizing the open-source programming language R, Iassemble a suite of metrics known as DAMS – the Dam Analysis and Metrics Suite – thatcombines several pre-existing metrics for characterizing dam impacts into one script. Thesemetrics include the Indicators of Hydrologic Alteration to characterize hydrologic change; themean streambed elevation to characterize vertical change in the river; and sediment mass balanceand flood magnitude reduction. By combining these schemas, DAMS provides a flexible andcomprehensive way to characterize the impact of dams on hydrology and geomorphology.I apply DAMS to two dams in diverse geographic settings: the Buford Dam on theChattahoochee River in Georgia and the Harris Station Dam on the Kennebec River in Maine.Both are hydroelectric dams with long stream gage records before and after dam construction. Ifound that the Buford Dam has caused a decrease in high flows in the Chattahoochee River aswell as a change in the seasonality of flows. I found that the Kennebec River has seen anincrease in high and peak flow volume after the construction of the Harris Station Dam, but thisincrease is less than comparable unimpounded rivers. The geomorphic data the ChattahoocheeRiver is fairly limited and cannot be access for the Kennebec River at all, meaning that DAMSwas unable to tell a complete story about how these rivers changed due to impoundment,highlighting the need for increased monitoring on all of the United States’ rivers.

- This study examines the institutional and emotional dynamics within a multidisciplinary team that consists of law enforcement (LE), the Department of Health and Human Services (DHHS), and sexual assault support staff who handle child sexual abuse cases. Employees interpret trauma differently depending on the organizational framework they operate within. The way professionals construct trauma shapes caregivers’ outlook on the process and ultimately affects how they care for their children. While LE and DHHS prioritize legal compliance, the sexual assault support staff advocate for trauma-informed care. Using semi-structured interviews with seven sexual assault support staff members who identified as women or non-binary, this research explores the way they manage the gendered burden of emotional labor, the systemic undervaluation of trauma-informed practices, and the emotional challenges caregivers face in supporting child survivors. Findings show the friction between the multidisciplinary team, emphasizing the need for integrated trauma-informed training and community-based support systems for caregivers.
