About

Dorothea Kolossa’s research lies at the intersection of audio signal processing, machine hearing, and robot audition, with a core focus on enabling machines to perceive and interact with complex acoustic environments. Her major contributions center on binaural processing and active acoustic exploration, where she has developed methods for robust sound source localization using microphone arrays. Notably, her work on direction-of-arrival (DoA) estimation in reverberant spaces and Monte Carlo-based active binaural localization allows robotic agents to proactively reduce uncertainty in sound source estimates through motion. She has also advanced the field of acoustic simultaneous localization and mapping (SLAM), introducing potential-field-based frameworks for mobile robots to build acoustic maps while localizing themselves. Her highly cited 2013 introduction to binaural processing (21 citations) serves as a foundational resource, while her 2017 study on DoA estimation (10 citations) demonstrates practical robustness under real-world conditions. Kolossa’s innovative integration of dynamic stream weights for audiovisual speaker localization further showcases her ability to fuse multimodal data adaptively. Her work is instrumental in pushing the boundaries of autonomous auditory perception, with direct applications in robotics, human-computer interaction, and smart environments.
