Postdoctoral positions with primary focus on first principles modeling is available at the University of Pennsylvania immediately. We are looking for a strongly motivated candidates to work on (a) identifying nanomaterials for energy storage and catalysis and (b) on the electronic properties of 2D materials and their heterostructures. Ideal candidates will have a background in materials science/computational physics/quantum chemistry with expertise in density functional theory and electronic structure simulations. The postdoctoral fellows will have the opportunity to be directly involved in complimentary experimental investigations, both at Penn and our collaborators in industry and academia. Candidates should send their CV with names of three references to [email protected]
