Nicole A. Benedek
Materials Science and Engineering
Dr. Benedek received her BS in Chemistry (with First Class Honors) and PhD in Chemistry and Applied Physics, both from RMIT University in Melbourne, Australia. Her doctoral work focused on fundamental theoretical studies of weak interactions in mixed organic-inorganic molecular crystals. As a postdoctoral fellow at Imperial College London, she studied the structures of grain boundaries in complex oxide ferroelectrics, with the goal of linking microstructure to electrical properties. As part of this work, she co-developed a computational technique for predicting the atomic-scale structures of interfaces in complex materials. Dr. Benedek continued her work on complex oxides as a postdoctoral fellow in Applied Physics at Cornell, where she discovered a new route to achieve electric field-control of the magnetization in a family of multiferroic perovskites, a class of materials that could enable the development of low-power electronic devices.
The Benedek group uses theory and first-principles calculations to advance fundamental understanding and create design rules for new classes of materials that may host new phenomena and properties. We are particularly interested in understanding and controlling the structures and properties of materials out of equilibrium. Recent work includes understanding how to induce extreme changes in material properties through ultrafast optical control of the crystal lattice (nonlinear phononics). Another major focus is on exploring the mechanisms of thermal transport in materials, with a view towards formulating design principles for dynamically controllable transport properties. Dr. Benedek’s research is supported by a CAREER award from the National Science Foundation, the Department of Energy, and the Cornell Center for Materials Research (an NSF MRSEC).
