Irina Arévalo holds a PhD in Mathematics from Universidad Autonoma de Madrid and a PhD in Artificial Intelligence from Universidad Pablo de Olavide, and is currently an Assistant Professor at Universidad Politecnica de Madrid. In her first PhD, she specialized in Complex Analysis and Operator Theory and has taught graduate-level courses in mathematical analysis in Mathematics, Physics and Engineering degrees. After her PhD she worked as a Data Scientist, Researcher in Artificial Intelligence, and Analytics Manager in several industries, such as banking and tech.

Her second PhD aligned with her current research interest, Distributed Machine Learning, especifically in Federated Learning. Her work has focused on new aggregations to build the federated global model, new encryption methods to ensure the security of the federated system, methodologies to federate Fuzzy Cognitive Maps, and explainability. Irina has published more than 10 papers in Complex Analysis, Applied Statistics, and Artificial Intelligence.
