Titin Handayani is a senior researcher with a background in environmental biology. She graduated from IPB University and specializes in biology. Currently, she works as a researcher, focusing on environmental biology research on landslides, which focuses on how vegetation, roots, and soil microorganisms influence slope stability. Plant roots strengthen soil structure, while microbes improve aggregation and nutrient cycling. This field develops nature-based solutions such as reforestation and bioengineering to reduce erosion, control water flow, and mitigate landslide risks sustainably.
