[{"content":"Modern data-intensive applications rely on graph databases, yet graphs frequently contain inconsistencies that violate structural constraints. My work addresses this from a human-centric perspective: rather than fully automated fixes, I develop interactive repair frameworks that keep users in control of the process.\nKey research questions # How can we design repair systems that are transparent and explainable to non-expert users? How can constraint violations be detected and resolved interactively, at scale? What role can Large Language Models play in assisting constraint mining and repair? Selected work # Grafixer — a system enabling user-centric repairs for property graphs, presented as a demo at SIGMOD 2025. User-Centric Property Graph Repairs — a full framework for interactive repair of property graphs, published in SIGMOD 2025. Interactive Graph Repairs for Neighborhood Constraints — introducing neighborhood-based constraint repair at EDBT 2024. Graph Consistency Rule Mining with LLMs — using LLMs to assist in mining graph constraints, at EDBT 2025. What If: Causal Analysis with Graph Databases — causal analysis framework for graph data, at VLDB 2025.

Previously, I was a postdoctoral researcher at Delft University of Technology and the Amsterdam Institute for Advanced Metropolitan Solutions (AMS).\nMy research sits at the intersection of Human-Computer Interaction and Data Management. I investigate how to integrate human perspectives and computational methods in the design, development, and deployment of data-intensive applications. My goal is to build systems that are not just efficient, but that are responsive to human characteristics, needs, and values.\nMy current work spans three main directions:\nHuman-Centric Graph Data Management — interactive and user-driven approaches to graph database repair, query formulation, and causal analysis. Crowdsourcing and Human-in-the-Loop Systems — quality-aware human-in-the-loop algorithms for data collection, integration, and analysis. Empathy-Centric Design — tools and methods for embedding empathy into participatory design and policy-making.
