UNIVERSITY PARK, Pa. — Four doctoral graduate students in Penn State’s Department of Geography will deliver research talks as part of the department’s Graduate Student Coffee Hour series at 3:30 p.m. on Friday, Feb. 20, in 112 Walker Building on the University Park campus. The event will also be accessible via Zoom.
Zhengrui Huang will present “Characterization and Modeling of Antarctic Ice Shelf Fractures.” Huang’s research interests focus on integrating heterogeneous spatial information into numerical models, including approaches such as computer vision, remote sensing, deep learning and optimization.
Ali Khosravi Kazazi will present “From Questions to Queries: An AI-powered Multi-Agent Framework for Spatial Text-to-SQL.” Kazazi’s broader interests include GeoAI and geospatial data science, with a focus on how AI-enabled methods can support real-world decision-making, including in public health.
Sooyoung Lim will present “Path vs. Places: Route-Level Crime Risk Driving Taxi and Shared Bicycle Substitution in New York City.” Lim’s research interests include GeoAI, spatial analysis, big data and transport geography, with a focus on applying explainable machine learning and spatial optimization approaches.
Lucy Thompson, a doctoral student in geography, will present “Appalachian Environmental Justice, Resistance, and the More-Than-Human Community.” Thompson is a human geographer interested in the intersection of environmental (in)justice, embodiment, more-than-human community and the expansion of natural gas infrastructure in central Appalachia, drawing on feminist geography and critical environmental theory.
This event is part of the fall 2026 Coffee Hour series hosted by Penn State’s Department of Geography. To learn more and access Zoom information, visit the Coffee Hour event webpage.
