Alex Siegenfeld is interested in combining chemical intuition with mathematical rigor to further the understanding of materials with exotic and useful properties.  In 2010, Alex represented the United States at the International Chemistry Olympiad, where he won a gold medal. As an undergraduate at MIT, he created a model that explained an unusual inverse melting electronic phase transition in strontium-doped lanthanum nickelate, a material similar in structure to the cuprate superconductors. He also conducted research on topological insulators, a recently discovered class of substances that have great technological potential due to their being insulating in the interior but conducting on the surface.
