Position Description: The Columbia Center for Computational Electrochemistry (CCCE) is seeking an Associate Research Scientist (ARS) with expertise in surface science, electrochemistry, first-principles electronic structure methods, and machine learning. The successful candidate will contribute to the development of computational models that describe interfacial reactions in electrochemical systems. Reactions at electrode–electrolyte interfaces and the resulting formation of solid-electrolyte interphases significantly affect battery performance, yet remain poorly understood. CCCE aims to establish quantitative, yet computationally efficient models to provide atomic-scale insights into these processes. The Center is located on Columbia’s Morningside Campus and is part of a vibrant, multidisciplinary research environment that offers excellent opportunities for career development. Qualifications: Applicants must hold a PhD in chemistry, chemical engineering, materials science, or a related field. Extensive experience in electronic density-functional theory, computational surface science, and the development of machine-learning models is required. A strong background in electrochemistry, particularly related to lithium batteries, is highly desirable.
