The professional career path coherently integrates clinical activity in the hospital setting, university teaching in Health Sciences, and applied research in medical physics, with a clear focus on translating knowledge into clinical and educational practice. This integration has enabled the development of a sustained line of work in radiotherapy, brachytherapy, and intraoperative radiotherapy, aligned with the real needs of the healthcare and university environments.
A Medical Physics Specialist since 2008, I carried out my professional work at the Complejo Hospitalario de Navarra until 2015, and at the Hospital Universitario Miguel Servet in Zaragoza from 2015 to the present, where I continue to perform my clinical duties.
From a research standpoint, my activity has focused on the development, validation, and optimization of advanced radiotherapy techniques, with particular attention to electronic brachytherapy, intraoperative radiotherapy (IORT), in vivo dosimetry, and end-to-end quality assurance procedures. These lines of work have resulted in scientific publications as first author in international journals indexed in the Journal Citation Reports (Q1–Q3), reflecting scientific leadership, thematic continuity, and methodological contributions relevant to the medical physics community.
From an applied perspective, the research conducted has contributed to improving the safety, accuracy, and efficiency of radiotherapy treatments, addressing real clinical problems through quantitative and reproducible approaches. The incorporation of open-source tools, real-time planning methodologies, and advanced dosimetric studies reinforces the innovative and transferable nature of these contributions.
In the teaching domain, the experience gained as a university lecturer in Health Sciences degrees, together with daily clinical activity, has enabled evidence-based teaching oriented toward professional practice, integrating my own research results into the educational process. This constant interaction between teaching, research, and clinical work has supported the consolidation of an academic line of my own, with an impact both on the training of students and healthcare professionals and on the improvement of clinical procedures.
Overall, the profile reflects a balanced and well-established trajectory as a clinician–teacher–researcher, characterized by the effective integration of clinical practice, high-quality scientific output, and university teaching, in line with current standards for academic and healthcare evaluation.
