This weekend is the Siemens Competition in Math, Science & Technology held at the University of Texas. Moreno is working with high school students Alexandra Ilic and Kevin Tian on a project that uses the power domination graph theory to find measure the performance of electrical networks. (Yeah, I didn't know what graph theory was either. This site describes it pretty well as a branch of math that looks how objects are connected to each other.)
Teams are competing for a scholarships ranging from $1,000 to $100,000 scholarship. Finalists will compete next month in Washington, D.C.
