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. Gregory Retallack’s academic foundation began in Sydney, Australia, where he attended Hurstville Public School, Epping Heights Public School, and The King’s School, Parramatta. His early curiosity for the natural world led him to pursue geology and biology at Macquarie University, earning a B.A. in 1973. His exceptional academic promise was evident when he graduated with First-Class Honours and the University Medal from the University of New England in 1974, followed by a Ph.D. in 1978. These formative years marked the beginning of a lifelong dedication to geology, paleobotany, and paleopedology.

Professional Endeavors

Dr. Retallack’s professional journey spans across continents and decades. His early teaching appointments included Northern Illinois University and Indiana University before he joined the University of Oregon in 1981, where he rose from Assistant Professor to full Professor and later served as Emeritus Professor. In addition to teaching and research, he directed the Condon Fossil Collection at the University of Oregon’s Museum of Natural and Cultural History, enriching public engagement with paleontology. His academic career reflects a blend of field research, mentorship, and scholarly leadership.

Contributions and Research Focus

A pioneering figure in paleopedology-the study of fossil soils-Dr. Retallack transformed understanding of ancient ecosystems, climate change, and evolutionary biology. His work on paleosols provided novel frameworks for interpreting paleoecological and geological records, particularly across critical intervals such as the Permian–Triassic boundary and the expansion of grasslands. His interdisciplinary contributions bridged geology, biology, and environmental science, making him a central figure in reconstructing Earth’s past environments and their role in shaping life.

Impact and Influence

Dr. Retallack’s influence extends well beyond his classrooms and field sites. His 331 publications have garnered more than 24,000 citations, with a remarkable h-index of 80—demonstrating both productivity and enduring scholarly impact. His recognition includes being elected Fellow of the Geological Society of America, Fellow of the American Association for the Advancement of Science, and numerous international lectureships. Awards such as the Antarctic Service Medal and the Earl Ingerson Award further underscore his scientific contributions to global research.

Academic Citations

Through his extensive research, Dr. Retallack’s findings are widely referenced in the scientific community. His work on fossil soils as indicators of ancient environments remains a cornerstone in geological and paleobotanical literature. The breadth of his citations-from paleoclimatology to evolutionary studies—illustrates the interdisciplinary resonance of his scholarship, placing him among the most highly regarded earth scientists of his era.

Legacy and Future Contributions

Even as an Emeritus Professor, Dr. Retallack continues to shape the scientific landscape. His role in curating fossil collections, developing educational materials, and authoring influential papers ensures that his contributions will guide future generations of geologists, paleontologists, and environmental scientists. His legacy lies not only in his groundbreaking research but also in the community of scholars he mentored and the public’s deeper appreciation of Earth’s deep history.

Conclusion

Dr. Gregory Retallack’s career exemplifies the qualities of a distinguished academic whose work redefined the study of ancient soils, ecosystems, and evolutionary change. His scholarship has left a lasting imprint on geology and paleontology, while his teaching and public engagement have broadened understanding of Earth’s dynamic history. With an enduring legacy and continued influence, Dr. Retallack stands as a fitting candidate for recognition through lifetime achievement honors.
