Current Research

Assistant Professor Quek’s group use first principles approaches to make predictions on the electronic structure and transport properties of materials. The uniqueness of the approach is that they can combine many-electron theories with mean-field theories into a practical and predictive tool to predict transport properties in nanoscale systems. They also work closely with experimentalists to understand experimental observations and guide experiments. In particular, they have recently focused on research involving emerging 2D materials.
