We combine information retrieval, applied machine learning, and foundation models to build systems that perform multi-step web search, integrate evidence from heterogeneous sources, and coordinate with humans or other agents. A particular focus is agentic information retrieval: understanding how AI agents search differently from people and how retrieval systems should adapt to these new users. The group develops open, reproducible methods and infrastructure for reliable, efficient, transparent, and controllable AI, with web search serving as both a core research problem and a real-world testbed.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" style=\"margin-top:var(--wp--preset--spacing--3);margin-bottom:var(--wp--preset--spacing--3)\"\/>\n\n\n\n<div class=\"alignnone wp-block-atom-research-teaser\">\n    <div class=\"container container-wider\">\n        <div class=\"row\">\n            <div class=\"col-12\">\n                    <p class=\"text-center m-0\">Keine Forschungsgebiete gefunden.<\/p>\n                <\/div>        <\/div>\n    <\/div>\n<\/div>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" style=\"margin-top:var(--wp--preset--spacing--3);margin-bottom:var(--wp--preset--spacing--3)\"\/>\n\n\n\n<h2 class=\"wp-block-heading has-h-4-font-size\">Short bio:<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Michael Granitzer is Fellow Professor of Information Retrieval &amp; Data Science at IT:U and Professor of Data Science at the University of Passau. His research is centered on the intersection of agentic artificial intelligence, applied machine learning, and information retrieval, with web search as a major application domain and research infrastructure. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">He develops intelligent systems that can retrieve, analyse, and use information in increasingly autonomous ways.
