Research profile

Professor Izabela Ewa Nielsen’s research focuses primary on applying operations research methods to enhance decision-making across sectors such as manufacturing, healthcare, supply chain management, and transportation. Through advanced problem modeling, optimization, artificial intelligence (AI), and solution development, she addresses complex real-world challenges involving uncertain or stochastic events.

In healthcare, her research aims to improve clinical outcomes in hematological and oncological malignancies by leveraging predictive biomarkers and developing validation frameworks for decision support tools used in clinical screening and prediction. The research utilizes advanced AI methods on real-world datasets to develop adaptive tools for personalized treatment. This work is carried out in collaboration with national and international clinical research centers and hospitals. She has e.g. been PI on projects with Novo Nordisk and EU, and PI from AAU on a project with Sygeforsikring Denmark. Professor Nielsen strongly values multidisciplinary collaboration, bridging academic research with real-world applications through cross-disciplinary projects and fostering strong partnerships with industry and clinical stakeholders to drive meaningful impact.

Professor Nielsen has a great interest in the mission “individualization and digital health” by making AI-driven patient stratification, digital health platforms for clinical decision-making, adaptive screening and monitoring tools, and by personalize treatment planning.

In addition to her research, Professor Nielsen serves as Vice-Chair of Danish Academy of Technical Sciences (ATV): Steering Group - Life Science Technology, WG2: Automation and healthcare productivity improvements and WG3: AI in healthcare support.

She is also a member of the strategic AAU Health Mission platform, which aims to strengthen coherence across sectors, provide individualized treatment, and support patients in managing illnesses. The platform develops technologies that consolidate patient data, enhances decision-support technology for tailored treatment and provides digital tools for daily health management. Furthermore, Izabela Nielsen is a Member of the Steering Committee for Health Data Science Network (SUND AAU).
