Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of death in the world, with an increasing prevalence as the world’s population ages. In the distal regions of the lungs, COPD is characterized by progressive emphysema due to an imbalance of proteases that continuously degrade essential extracellular matrix (ECM) proteins within the alveolar walls, causing fatal tissue impairment. This dissertation examines the unique properties of this diseased lung ECM in two parts: (1) As a key constituent in inflammatory signaling that leads to increased inflammation and progression of COPD, and (2) as a tool in three-dimensional (3D) in …

Wiring Attachment, Alexander K. Bacon

Theses and Dissertations

This thesis began with a question: can diagrams create understanding, or only reflect it? Through paintings that layer automotive wiring schematics with family photographs, I explore how the human attachment system resists easy mapping. Using digital tools like Photoshop and scanning, alongside analog methods such as papier-collé and photo transfer, I examine how systems built for clarity—like wiring diagrams—contrast with the layered, often messy realities of human relationships. Drawing from attachment theory’s empirical foundation, rather than the metaphorical leanings of psychoanalysis, my work investigates how emotional bonds form, falter, and repair over time. Material loss and layering are not flaws, …
