Knowledge doesn’t live in data—it lives in the connections we make between them.
I‘m a senior research scientist at Siemens AG Österreich and lecturer at IMC Krems. For over a decade, I‘ve worked on a deceptively simple problem: how do we make knowledge that exists in fragmented, incompatible systems speak to each other? Not by forcing everything into a single representation—instead, by building semantic frameworks that preserve what makes each system specialized while enabling intelligent coordination.
My work sits at the intersection of three worlds: the symbolic reasoning of ontologies and knowledge graphs, the practical constraints of industrial systems, and emerging neural approaches to knowledge engineering. Most of my time goes to concrete problems in industrial domains—rail infrastructure, manufacturing, smart buildings. I‘ve learned that lasting knowledge systems aren‘t imposed from above—you work with the standards organizations maintain, respect the tacit expertise in their tools, and create abstraction layers that let diverse representations coexist and coordinate.
I‘m fascinated by the moment when tacit knowledge becomes explicit—when something an experienced engineer “just knows” gets articulated so machines can reason about it and humans across teams can share it. Currently I‘m exploring how symbolic knowledge graphs and generative models can work together—how AI accelerates the capture and validation of expert knowledge while symbolic frameworks keep that knowledge auditable, transparent, and under human control. This is the direction industrial AI should go: not replacing expertise, but making it explicit and shareable.
If your problem involves making incompatible systems interoperable, capturing tacit domain knowledge, or building transparent AI systems grounded in structured reasoning, let‘s talk. I work with organizations on consulting and research projects at the frontier of semantic technologies and industrial practice.
