Charles Rosenblatt

Charles Rosenblatt received his B.S. degree in physics in 1974 from the Massachusetts Institute of Technology, and his Ph.D. degree in applied physics in 1978 from Harvard University. Following a postdoctoral fellowship at the University of California’s Lawrence Berkeley Laboratory, he became a Research Physicist at the Francis Bitter National Magnet Laboratory at MIT in 1980. In 1987 he joined the physics faculty at Case Western Reserve University, where he is currently a Professor of physics and macromolecular science. Rosenblatt has published approximately 170 refereed journal articles, has four patents, and was elected as a Fellow of the American Physical Society in 1996. His research centers on soft condensed matter, and has two thrusts. His primary concentration involves liquid crystals and complex fluids, where he uses light scattering, ellipsometry, synchrotron X-ray scattering, atomic force microscopy (AFM), and near field scanning optical microscopy (NSOM) to investigate a number of physical properties of these materials, especially phase transition and interface effects. Rosenblatt’s other thrust involves the study of fluids in controlled gravitational environments by magnetic levitation, which has the effect of creating a uniform upward force on the fluid. Rosenblatt has received more than twenty years of uninterrupted single-investigator support from the National Science Foundation. He has been funded by the US Department of Energy Office of Basic Energy Sciences, NASA, the Petroleum Research Fund of the American Chemical Society, and the Nissan Chemical Industries.
