Institut für Informationsverarbeitung (TNT)

Lars Rumberg studied mechanical engineering at the Leibniz Universität Hannover with focus on robotics and autonomous systems. He received his master’s degree in 2018. After graduating he joined the Institut für Informationsverarbeitung (TNT) at Leibniz University Hannover where he currently works as a research assistant.

His current research interests are in the field of machine learning for automatic speech recognition of children's speech and the analysis of multimodal human-human and human-computer interaction.
