Current Research

  • Associate Professor Quek’s group uses first principles approaches to make predictions on the electronic structure, vibrational properties, and transport properties of materials. The group has developed state-of-the-art methods to understand the physical mechanisms governing macroscopic observables. Recent research focus includes the level alignment at interfaces involving 2D materials and/or organic materials, quantum emitters in 2D materials, as well as the control of valleytronic materials with external magnetic fields.
