Invited Speaker: Kate Farrahi

Session Chair: Nic Lane

Title: Machine learning for mobile health and digital epidemics

Bio: Kate Farrahi is an assistant professor 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. She obtained her PhD in Computer Science from the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland.
