BiliScreen: Scleral Jaundice Detection with a Smartphone

Jaundice in the sclera is one of the few recognizable symptoms that can lead to a diagnosis of pancreatic cancer, yet the disease has one of the worst survival rates because symptoms are only recognized in their later stages with the help of a doctor. We are working on a smartphone app that allows anyone to screen themselves for jaundice using the phone’s camera.

Drunk User Interfaces (DUI): Determining Blood Alcohol Level through Everyday Smartphone Tasks

Testing for sobriety usually only happens after someone has gotten behind the wheel and started driving. Making sobriety testing more pervasive could help prevent such situations. We are conducting a rigorous study that examines how alcohol impacts performance on simple smartphone tasks.

PupilScreen: Using Smartphones to Assess Traumatic Brain Injury

Before a person suffering from a traumatic brain injury reaches a medical facility, measuring their pupillary light reflex (PLR) is one of the few quantitative measures a clinician can use to predict their outcome. PupilScreen is a smartphone app and accompanying 3D-printed box we are developing that combines the repeatability, accuracy, and precision of a clinical device with the ubiquity and convenience of the penlight test that clinicians regularly use in emergency situations.
