At its core, we pursue domain-informed signal processing that bridges classical methods with modern machine learning frameworks \u2014 including deep learning and generative models. A central goal is to develop models that are not only powerful, but also interpretable, tunable, and efficient in practice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Our work is structured around three complementary research pillars, as illustrated in the figure: audio &amp; speech, BCI, ExG, and sensor signal processing with multimodal information fusion, and analytics &amp; representation learning. Together, they rest on solid foundations \u2014 deep signal processing expertise, concrete research problems driven by industry applications, and fundamental, blue-sky studies with high risk and high potential impact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Key thematic areas include (bio-)signal analytics (e.g., EEG\/ExG), brain\u2013computer interfaces (BCI), signal detection and enhancement, sensor and information fusion, as well as time-series analysis and anomaly detection.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"765\" height=\"604\" src=\"https:\/\/www.hsu-hh.de\/sigma\/wp-content\/uploads\/sites\/944\/2026\/10\/pillars.png\" data-credit=\"Nilesh Madhu\" alt=\"Diagram of a house-like structure: three blue pillars labeled &quot;Audio &amp; Speech,&quot; &quot;BCI, ExG, Sensor signal processing &amp; Multimodal information fusion,&quot; and &quot;Analytics &amp; Representation learning,&quot; resting on a green three-layer foundation of &quot;Domain-informed signal processing, ML, Deep learning,&quot; &quot;Industry collaboration,&quot; and &quot;Fundamental (blue-sky) research,&quot; topped by an orange roof listing applications: Healthcare, Defense, Industrial Monitoring, Communications &amp; Entertainment, Information Management.\" class=\"wp-image-199\" srcset=\"https:\/\/www.hsu-hh.de\/sigma\/wp-content\/uploads\/sites\/944\/2026\/10\/pillars.png 765w, https:\/\/www.hsu-hh.de\/sigma\/wp-content\/uploads\/sites\/944\/2026\/10\/pillars-300x237.png 300w\" sizes=\"auto, (max-width: 765px) 100vw, 765px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Our research is dedicated to the intelligent sensing, processing, and analysis of (bio-)signals.
