Holger Roth

Holger Roth, is a principal federated learning scientist at NVIDIA, specializing in developing distributed and collaborative software and models for various industries using federated learning and analytics. He has been exploring the topic both from theoretical and practical standpoints. During the COVID-19 pandemic, he led the experimentation of a federated learning study involving twenty hospitals around the globe to train more generalizable models for predicting clinical outcomes in symptomatic patients. His other research interests include computer-assisted annotation, active learning, and natural language processing. He served as an Associate Editor for IEEE Transactions of Medical Imaging and holds a PhD from University College London, UK. In 2018, he was awarded the MICCAI Young Scientist Publication Impact Award.
