Research interests  

My research interest is in understanding of how human activities and environmental factors affect composition, diversity, and functioning within different trophic levels of ecosystem and across the entire multitrophic community. I believe it is important to bring together the System Modelling and Assessment approaches and empirically derived ecosystem measurements in order to enhance our understanding on the complexity of real-world multitrophic ecosystems.
