Name Simone Piaggesi
Professional Title AI Researcher & Data Scientist

Professional Summary

Data Scientist and AI Researcher currently working on Explainable and Trustworthy AI. Over the last 6+ years, I have developed ML methods applied to problems spanning drug sensitivity analysis, tabular data modeling, and graph representation learning, translating research advances into reliable tools that support AI-assisted decision-making in scientific and real-world settings.

Experience

  • 2023 - Present

    Pisa, IT

    Postdoctoral Researcher
    Department of Computer Science, University of Pisa
    KDD Lab member. ERC Advanced Grant XAI project team (2023-2025). Co-writer of the ERC Proof-of-Concept ILLUME-4-Science and WP-leader (2025-2026).
    • Designed and implemented meta-encoding pipelines to produce local explanations without per-sample surrogate retraining, achieving orders-of-magnitude faster inference and supporting XAI-assisted scientific hypothesis formulation (e.g., discovery of gene-gene interactions driving cancer cell drug response from transcriptomics data)
    • Built robust interpretability and counterfactual methods, improving explanation stability and auditability, outperforming SHAP/LIME while reducing explanation variance.
  • Oct 2022 - Feb 2023

    Turin, IT

    Research Intern
    CENTAI Institute
    Visiting internship within the Responsible AI group led by Principal Researcher André Panisson.
    • Built self-explainable graph neural networks that improve produce explainable graph features usable in downstream link prediction and node classification workflows.
  • Sep 2022

    Delft, NL

    Research Intern
    Delft University of Technology
    Visiting internship within the Web Information System group led by Associate Professor Avishek Anand, within the Software Technology department.
