The use of saliva sampling as a noninvasive way for drug analysis as well as the monitoring systems within the body has become increasingly important in recent research. Because of the growing interest in saliva, this project proposes a way to analyze sodium ion concentration in a saliva solution based on its fluorescence level when in the presence of a sodium indicator dye and recorded with a smartphone camera. The dyed sample was placed in a specially designed housing to exclude all ambient light from the images. A source light of known wavelength was used to excite the fluorescent dye and the smartphone camera images recorded the emission light wavelengths. After analysis of the images using ImageJ, it was possible to create a model to determine the level of fluorescence based on sodium ion concentration. The smartphone camera image model was compared to readings from a standard fluorescence plate recorder to test the accuracy of the model. The study found that the model was accurate within 5 % as compared to the fluorescence plate recorder. Based on the results, it was concluded that the method and resulting model proposed in this study is a valid was to analyze saliva or other solutions for their sodium ion concentration via images recorded by a smartphone camera.

The action/adventure game Grad School: HGH is the final, extended version of a BME Prototyping class project in which the goal was to produce a zombie-themed game that teaches biomedical engineering concepts. The gameplay provides fast paced, exciting, and mildly addicting rooms that the player must battle and survive through, followed by an engineering puzzle that must be solved in order to advance to the next room. The objective of this project was to introduce the core concepts of BME to prospective students, rather than attempt to teach an entire BME curriculum. Based on user testing at various phases in the project, we concluded that the gameplay was engaging enough to keep most users' interest through the educational puzzles, and the potential for expanding this project to reach an even greater audience is vast.

The mountains of western North America are spectacular and diverse, from sheer walls of crumbling black limestone in the Canadian Rockies, to smooth glacially polished granite in the Wind River Range, to gargantuan ice-clad volcanoes in the Cascades. These great bastions of rock, snow, and ice, still very much wild and untamed, provide an incredible arena for adventure, exploration, and challenge. Over the past three years, I have devoted thousands of hours to exploring these vast wild places, climbing high peaks, steep cliffs, and frozen waterfalls. In doing so, I studied the rich geologic history of the mountains. This thesis project is a compilation of stories and images from those adventures, along with the stories of the mountains themselves: how the rocks were formed, thrust skyward, and sculpted over the ages into their present, glorious form. The photographic and detailed narrative of the geology and adventures is on a new website called Cloud Piercers, which currently features three geologically diverse mountain massifs: (1) Mount Rainier, an active volcano in the Cascade Range of Washington; (2) Mount Robson, the highest peak in the Canadian Rockies, within a terrain of folded Paleozoic sedimentary rocks; and (3) the Wind River Range of Wyoming, composed mostly of Archean metamorphic and granitic rocks. This website will be expanded in the future as the geologic studies and adventures continue.
