Overview

This PhD position at the University of Luxembourg focuses on studying how organizations maintain meaningful control over AI agents that continuously learn from user interactions. The research addresses two core challenges: determining when an agent should proactively act versus waiting for explicit instructions, and detecting behavioral drift in agents to ensure their behavior remains aligned with validated baselines. The work combines theoretical research, system development, and empirical evaluation with real users in operational environments. The successful candidate will collaborate with academic and industrial partners, particularly a major Luxembourgish energy utility, and contribute to open-source software tools. The position is based at the UBIX Research Group within the Interdisciplinary Centre for Security, Reliability and Trust (SnT).

What you'll do

  • Conduct research on human-AI interaction, focusing on how agents calibrate initiative and present choices without overwhelming users.
  • Develop methods for detecting behavioral drift in learning AI agents and designing mechanisms to restore trusted behavior.
  • Design and implement proof-of-concept software tools for AI agents, with a focus on open-sourcing where applicable.
  • Conduct empirical studies with real users in operational industrial settings to evaluate AI agent performance.
  • Collaborate closely with academic and industrial partners to disseminate research findings through publications and project activities.
  • Present research results to project teams, industrial partners, and academic communities.
  • Publish findings in scientific journals and conferences, contributing to the broader AI research community.
