Human-AI Co-Exploration & Visualization in Design (PhD)

Date of publication: March 19th, 2026 ; I&I research group (Prof. Denis Lalanne)

Complex design decisions (whether reshaping a neighborhood, reimagining a workplace, or planning a building renovation) involve dozens of actors with competing values, uncertain constraints, and long-lasting consequences. Yet these decisions remain largely intuition-driven, fragmented, and poorly supported by computational tools. This PhD investigates how interactive intelligence (genuine cognitive dialogue between humans and AI) can enable all actors to jointly navigate such complexity. Rather than positioning AI as an autonomous recommender that humans passively validate, this research explores genuine cognitive partnership: stakeholders and AI continuously co-explore design spaces together, surfacing trade-offs, uncovering unseen possibilities, and negotiating competing objectives in real time. At the core is the design of interactive trade-off visualizations that make creative, sustainable, and participatory dimensions legible and negotiable for all — with AI as an active exploration partner while humans retain agency over values and final judgment. Through iterative design studies and real-world deployments, the PhD will produce validated interactive prototypes, empirical evidence on human-AI co-exploration, and theoretical contributions to participatory design and interactive intelligence. Applications within the Smart Living Lab (University of Fribourg + Engineering school of Fribourg + EPFL) will be considered.

Expected outcomes: Interactive prototypes, controlled and in-the-wild user studies, and publications at CHI, CSCW, UIST, and venues such as Design Studies or Automation in Construction.

Profile sought: CS or Engineering background with strong HCI orientation, interest in visualization and participatory methods, and solid prototyping skills. Experience with LLMs or information visualization is a plus. No domain expertise in architecture or engineering required. The project is embedded in the Human-IST Institute and the Smart Living Lab collaborative network, with access to real deployment contexts and interdisciplinary expertise in human-building interaction.

Start: as soon as possible. Applications reviewed from April 1st, 2026.
