Personal homepage

Kate Farrahi is an assistant professor in at the University of Southampton working in the vision, learning and control VLC Group . The focus of her research is on machine learning, particularly deep learning, often applied to health-related applications. She is interested in developing machine learning techniques to address novel sensor-driven healthcare problems, including natural language processing and vision related applications such as medical imaging and contactless vitals measurements. Prior to joining Southampton, she was a research assistant at Idiap Research Institute. She obtained her PhD in Computer Science from Swiss Federal Institute of Technology in Lausanne (EPFL).
