This project simulates the growth of a slack community using reinforcement learning. It is comprised of a simulator and accompanying graph visualization web application. Building an online community is one of the major challenges in the evolution of civilization nowadays. New online forums, chat-rooms, and social networks are springing up every day. Management of these online communities involves many challenges. Management of a community is an inherently human action ranging in scope from the 3-person family to an international conglomerate. Current attempts to manage online communities, focus only on understanding hierarchy on a routine basis. This project aims to manage the growth of a simulated “Slack” community in real time by the use of reinforcement learning. Using this technique to determine the best internal matches will significantly increase group engagement. You can view the demo at https://percey.herokuapp.com

Dermashift - Diagnostic device for pressure ulcer formation Pressure ulcers (PUs), i.e. bed sores, are chronic injuries largely affecting over 2.5 million patients annually. Although considered preventable, present standards to detect PUs have low specificity and sensitivity or are difficult to implement due to time or cost constraints. PUs are caused by prolonged pressure, resulting in ischemia and tissue necrosis. Since pressure-induced ischemia alters blood reperfusion and oxygen concentration levels, measuring O2 changes prior to and after reperfusion is a promising indicator for PU formation. We have a created a low-cost, handheld device that induces reperfusion (via an automated loading mechanism) and measures the changes in O2 (via reflectance pulse oximetry), thus quantitatively assessing PU formation based on the change in O2 in clinical settings.

When you arrive at a conference the first question you ask is who should I meet? This web app connects you to people at a conference based on compatibility between conference attendees. It takes into account topical interests and skills and matches you with possible mentees, peers, and mentors to meet during the conference.
