Alexander Horsch


Professor

Job description

Alexander Horsch, born 1955 in Augsburg, Germany, is professor in computer science. His main scientific contributions are in the creation of systems for medical image analysis and for biosignal analysis, also in combination with telemedicine services. Early work focused on computer aided diagnosis of cancer, where I was one of the drivers in developing a system for the early detection of melanoma which was patented and integrated in a commercial product. Lately I worked on accelerometer data analysis for research on physical activity in the framework of large populations studies. Current emphasis is on methods from artificial intelligence, including machine learning and deep learning, with a focus on use cases from medicine, biology, and public health.
