Professor Chen’s research interests include first-principles modelling and design of complex meta-materials, in particular transition metal oxide heterostructures; ab initio calculations of ground state and excited state properties of correlated systems; as well as method development in materials theory. His work has appeared in Phys. Rev. Lett., Nano Lett. and Advanced Materials.
