I am a landscape ecologist with an active research programme on land use and land cover change modelling at multiple temporal and spatial scales. 

Land use/land cover change (LULCC) driven by rapid human population growth and increasing demand for agricultural and forest products has far-reaching implications. To assess and monitor changes in biodiversity, climate, ecosystem services and ultimately human well-being, LULCC is an essential layer of information that is used in a wide range of applications: species distribution modelling, risk assessments (e.g., floods, fire), ecosystem services change (e.g., provision, regulation and cultural), epidemiological studies (e.g., spread of infectious diseases), landscape planning (e.g., new dams or roads), agricultural and forestry productivity estimates (e.g., yields), among others. My active research programme is on developing and applying novel tools that can help policymakers know where and at what rate LULCC is occurring and is expected to occur under future scenarios, thus allowing them to anticipate its impacts, and develop preventive and/or adaptive measures. I am to use these tools to address critical conservation issues, such as understanding the impact of changing socio-economic dynamics (e.g., the peace agreement in Colombia); supporting the implementation of conservation and restoration policies (e.g., ecosystem restoration subsidies); and the planning of future infrastructure developments, with a strong emphasis on involving key stakeholders in the modelling process. Furthermore, the need for accurate LULCC projections and scenarios is validated by the focus of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), particularly the Scenarios and Models Expert Group, with whom I have been working. My research is highly interdisciplinary, and I have forged research collaborations with colleagues from across scientific disciplines (in particular: physical sciences, statistics, socio-ecology, computing, machine learning, conservation, remote sensing, and biodiversity), institutions and countries. 

The main goal of my research is to inform day-to-day decisions made by landscape managers and policy makers that can impact the sustainability and dynamics of landscapes worldwide, with particular focus on sustainable management of living natural resources. This is critical to address some of the greatest challenges of our world, such as climate change and sustainable food systems, in the perspective of continued human population growth.
