You are expected to contribute to the development of internationally visible, foundational research in AI-driven semantic
structure extraction, automated reasoning-flow modeling, and adaptive content generation. The research focuses on methods for
analyzing and representing deep semantic and pedagogical structures in scientific and educational materials; high-fidelity
extraction of conceptual and reasoning blocks; inference-time rationale generation; and adaptive, learner-aware sequencing of
content. This includes work on semantic parsing, structured NLP, graph-based neural models, metacognitive prompting, ontology
alignment across disciplines, and human-in-the-loop optimization.
In this context, interdisciplinary research is strongly encouraged—particularly collaborations spanning computer science,
computational linguistics, cognitive science, and the learning sciences. You will contribute to developing datasets, baseline
models, personalized learning engines, reasoning-graph representations, cross-domain mapping algorithms, and RLHF-style feedback
loops that improve system interpretability and instructional quality. The successful candidate will also contribute to
high-quality publications, release research prototypes, and support demonstrator systems that deliver structured semantic
extraction, rationale-aware content generation, and cross-domain transfer of reasoning structures.
Additionally, the successful candidate is expected to support teaching activities in areas such as Machine Learning, Natural
Language Processing, AI in Education, Knowledge Representation, and Python-based analytical seminars at the BSc, MSc, and PhD
levels. Responsibilities include assisting in course delivery, advising students, supervising Bachelor/Master theses, and engaging
in methodological innovation for online, hybrid, and in-person learning environments. The university provides strong support for
early-career researchers, including mentorship, administrative assistance, access to computational resources, conference funding,
and opportunities to collaborate with other research groups and industrial partners working at the intersection of AI and digital
education.
