Question: What state does Sang-Wook Cheong work as a materials scientist?
Related documents: [0]  [DOC] Sang Wook Cheong is a Korean American materials scientist at Rutgers University. He has made ground-breaking contributions to the research field of enhanced physical functionalities in complex materials originating from collective correlations and collective phase transitions such as colossal magnetoresistive and colossal magnetoelectric effects in complex oxides. He has also made pivotal contributions to mesoscopic self-organization in solids, including the nanoscale charge stripe formation, mesoscopic electronic phase separation in mixed valent transition metal oxides, and the formation of topological vortex domains in multiferroics, which was found to be synergistically relevant to mathematics (graph theory) and cosmology.
