Peng Luo
Assistant Professor
School of Earth, Environment, and Sustainability, University of Iowa
I am a tenure-track Assistant Professor in the School of Earth, Environment, and Sustainability at the University of Iowa, where I lead research at the intersection of GIScience, GeoAI, and spatial data science. Previously, I was a postdoctoral researcher at the MIT Senseable City Lab, and I received my Ph.D. from the Chair of Cartography and Visual Analytics at the Technical University of Munich. My research focuses on Trustworthy GeoAI, with particular interests in spatial explicit modeling, geospatial explainable AI, uncertainty quantification for GeoAI models, and multi-agent GeoAI.
I am hiring! Two fully-funded Ph.D. positions for Fall 2027 — see openings →Research
Spatial Modeling
Spatial Explicit Modeling
Models that explicitly encode spatial heterogeneity, dependence, and interaction into prediction and association analysis.
Trustworthy AI
Trustworthy GeoAI & UQ
Model-agnostic frameworks for spatial uncertainty quantification, explainability, and visual analytics.
Generalization
Transferable & Scalable GeoAI
LLM-driven geospatial model discovery, graph-based community detection, and scalable urban analytics.
