Integrated Biological Control and Ecosystem Management (IBEM) Group

This group is comprised of multifaceted nature of work. Focused on understanding and mitigating the impacts of invasive species, this group conducts research on the ecological effects of invasive alien plants, the use of biological control agents, and the discovery of novel bioremediation fungi. Furthermore, we assess the socio-economic implications of invasive species and their management. Our work aims to develop sustainable solutions for managing invasive alien species and preserving ecosystem health.
