His work focuses on interdisciplinary research spanning mathematics, computational and biomedical sciences. Eder has held an MRC Skills Development Fellowship and a EU Horizon 2020 secondment to develop quantitative methods for the diagnosis and management of endocrine conditions (see ULTRADIAN). He has established international partnerships supported by the Global Challenges Research Fund, the Royal Society Newton Mobility Grant, and collaborations via MRC, EPSRC, NIHR and intra-mural funding. His collaborations with clinicians, computer scientists and other mathematicians span several Russell Group UK universities, as well as research institutions in the USA, Norway, Sweden, Greece, Korea, Mexico and Australia. Committed to patient and public engagement and science communication, Eder regularly participates in events such as Pint of Science, Festival of Neuroscience, and organises workshops bringing together patients, clinicians and researchers to collaborate in addressing current challenges in healthcare.
