Ms. Jiyoon Lee | Graph Data | Best Researcher Award

Ewha Womans University | South Korea

Ms. Jiyoon Lee is a doctoral researcher in Big Data Analytics at Ewha Womans University, Seoul, Korea, with expertise in graph data structures, algorithms, and GeoAI applications. Her research explores urban mobility, safety, and congestion management through advanced spatiotemporal modeling. She has presented her work at major conferences, including SIGSPATIAL 2025, where she introduced a novel GraphLSTM-Attn framework for modeling stopped vehicle dynamics on urban backstreets, and Asiacarto 2024, where she proposed a CCTV-based trajectory algorithm for road congestion and alleyway safety. Her scholarly contributions include multiple publications in the ISPRS International Journal of Geo-Information, such as studies on pedestrian congestion and safety in urban alleyways and the development of PGTFT, a lightweight graph-attention temporal fusion transformer for predicting pedestrian congestion in shadow areas. Through her innovative research at the intersection of graph data and GeoAI, she continues to advance data-driven solutions for safer and more efficient urban environments.

Early Academic Pursuits

Dr. Raymond Tyoakaa Iorhemen’s academic journey is grounded in a strong foundation of chemical sciences, beginning with a B.Sc. in Pure Chemistry from the University of Jos, Nigeria, in 2010. His undergraduate project, focused on the spectrophotometric determination of paracetamol, demonstrated his early inclination towards analytical methodologies. Pursuing further specialization, he obtained a Postgraduate Diploma in Environmental Chemistry with Distinction in 2015 and an M.Sc. in Analytical Chemistry in 2018, both from Ahmadu Bello University (ABU), Zaria. His postgraduate dissertation involved a significant environmental application—remediation of toxic elements in local clays. Currently, he is a doctoral candidate at ABU, Zaria, set to complete his Ph.D. in Analytical Chemistry in December 2024. His thesis explores the development of novel cholesteryl chloroformate-based metallogelators for oil spill remediation, positioning him at the intersection of innovation and environmental stewardship.
