Research interests

Optical methods enable rapid, noninvasive, and three-dimensional imaging with micrometer scale resolution. My research interests are the development of new optical methods for biomedical imaging – in particular optical coherence tomography (OCT) – and their application for improved diagnostics of diseases in both clinical and preclinical research.

• Optical imaging setups for retinal and microscopic imaging
• Image processing and analysis
• Longitudinal studies in biomedical research settings
