Sickle cell disease is a genetic disorder that can cause substantial helath problems. It is the result of a mutation in the DNA coding for hemoglobin. As a result of changes in two important amino acids, a person suffering from sickle cell disease will have erythrocytes that do not maintain the typical biconcave shape and instead for a crescent shape. Individuals with sickle cell disease may have many health problems tied to their irregular hemoglobin. The unusual shape of the erythrocytes leads to a much shorter cell life, which means that even though bone marrow remains active long past childhood to try to keep up with the loss of erythrocytes, the body is still unable to accommodate the rapid death of erythrocytes. The malformed erythrocytes can also cause vascular occlusion, blocking blood vessels and slowing blood flow. While sickle cell disease has the potential to spread worldwide, it is particularly common in Africa. This may be because people with the sickle cell trait have a high resistance to malaria, making them more likely to survive that ubiquitous disease and pass on their traits to their offspring. However, the mortality rate in young children with sickle cell disease is very high, in part because the spleen, already stressed by filtering out dead erythrocytes, has difficulties filtering out bacteria. One of the keys to stopping the spread of the disease is neonatal screening, but this requires specialized equipment that is fairly uncommon in rural areas, as can be seen in Kenya. Therefore, it would be highly beneficial to develop a more cost-effective and widely available method for testing for sickle cell disease.

Diabetes is a growing epidemic in developing countries, specifically in rural Kenya. In addition to the high cost of glucose testing, many diabetics in Kenya do not understand the importance of testing their blood glucose, let alone the nature of the disease.

Diabetes is a growing epidemic in developing countries, specifically in rural Kenya. In addition to the high cost of glucose testing, many diabetics in Kenya do not understand the importance of testing their blood glucose, let alone the nature of the disease. This project addresses the insufficiency of educational materials regarding diabetes in rural Kenya. The resulting documents can easily be adjusted for use in other developing countries.

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.
