Research synopsis
My group focuses on developing first-principles quantum mechanical methods to model the real materials and devices. For this, we develop first-principles methods for open quantum system (OQS), and employ machine learning to improve the accuracy of first-principles quantum mechanical methods so that quantitatively precise prediction of material properties is possible.
