Dr. Jae-Hyun Park specializes in soil–plant interactions and applied ecological restoration. His research examines how soil properties, water availability, light, and microclimate influence plant establishment, growth, and stress responses, with the goal of translating scientific findings into practical management strategies. He has conducted extensive field monitoring and controlled experiments in forest restoration sites, nurseries, urban green spaces, and cultivation systems. His main research focuses on conserving threatened forest species, particularly Korean fir and other subalpine conifers. He integrates soil and microclimate assessment, plant growth and survival monitoring, and genetic-diversity-informed planting design to identify barriers to successful restoration. His studies also address deicer-affected soils, soil amendments, salt-tolerant vegetation, and sustainable urban cultivation. His strengths include designing field-based experiments, interpreting complex soil and plant responses, and integrating long-term environmental observations with statistical and spatial analysis. He is equipped to assess restoration sites, diagnose plant establishment problems, evaluate management treatments, and develop evidence-based guidelines. Building on these capabilities, he aims to advance sensor- and machine-learning-assisted approaches to plant stress prediction, smart irrigation, and climate-resilient restoration.
