Research Interests


My main motivation in doing research holds in the word “Conservation”. I want my research to help, directly or indirectly, conserving species and nature. This applied will is combined with a strong appetence for large and global spatial scales. Indeed, I like to think about the global impact that humans have on biodiversity and about the solutions that we have in our hands to mitigate biodiversity loss at global scale. Studying conservation effectiveness and participating in the development of indexes to track biodiversity loss and conservation effects are thus central in my research interests.


At iDiv I am working on the sRedList project led by Luca Santini and Moreno di Marco. This project aims at creating an innovative and consistent framework for prioritising the updates of Red List assessments. The general goal is to create a dynamic list of species that need to be reassessed because we expect their extinction risk to have changed since their last assessment (e.g., because their habitat has been recently converted). To do so, we will cross species distribution maps and traits with maps of human pressure to identify priority species for reassessment.
