Research interests

I have a broad interest in the functional ecology of animal and plant communities in both natural and cultivated ecosystems affected by global changes. Over the last decade, I have been conducting research programs in a wide variety of ecosystems - from the amazon rainforest to the high altitude agricultural landscapes to glacier fore fields- along the altitudinal gradients of the tropical Andes (mainly in Ecuador and Bolivia). I am interested in integrative and trans-disciplinary studies, in particular in modelling approaches coupling physical, biological and social systems. Most of my research is conducted in the framework of the Joint International Laboratory BIO_INCA that I have created in 2018 in collaboration with Ecuadorian and Colombian partners (see below). I also have a strong interest in science communication through a wide array of medias (books, photography exhibitions, webdocs, movies, see below).

International Joint laboratory (LMI) - @bio_inca

The main objective of the LMI BIO-INCA is to promote the emergence of an operational research platform, specialized in the integrative study (from genomes to socio ecosystems) of natural and cultivated phytosystems of the Andean region (highlands and foothills). The research engendered by this structure is aimed at the interface between the basic and applied sciences, with the objective of proposing concrete solutions to the adaptive management of natural and cultivated phytosystems. This research is organized into four main scientific objectives: 1) the characterization of cultivated and wild biodiversity, 2) the study of biological interactions, 3) the study of ecosystem services and nature-based solutions, and 4) the development of innovative tools and training programs.
