Highlights: Katharina Doblhoff-Dier is a computational electrochemist who studies atomic scale processes at electrode–electrolyte interfaces, which is where electrochemical reactions take place. To address the complexity of these systems, she applies a broad range of theoretical approaches, ranging from electronic structure methods and molecular dynamics simulations to mean-field modeling. Katharina Doblhoff-Dier contributes to major collaborative research initiatives in electrochemistry, including the Dutch Gravitation Programme ANION and the EU COST Action EU-CONCERT. Driven by the ambition to bridge theory and experiment, her mission is to advance theoretical electrochemistry to provide models that support a clearer interpretation of experimental results and ultimately enable rational design in electrochemistry.
