Information of interest
I received my PhD from the Centro Singular de Investigación en Tecnoloxías Intelixentes (CITIUS), University of Santiago de Compostela, Spain, in 2017. During my doctoral studies I developed a novel knowledge-based framework for time series interpretation based on abductive reasoning that has been successfully applied to automatic ECG interpretation and classification. In the 2018-2022 period I worked as a research associate with the Embedded Systems Laboratory (ESL) at the École polytechnique fédérale de Lausanne (EPFL), and during 2022 I was with the Mathmode group at the University of the Basque Country (UPV/EHU). Since January 2023 I am with the BCAM - Basque Center for Applied Mathematics with a Ramón y Cajal Research Fellowship. My research interests include knowledge representation, non-monotonic temporal reasoning, efficient machine learning, event-based sensing, and their application to biosignal abstraction and interpretation in energy-efficient setups.
