Welcome to my personal home page! 

I am Belgian, born in the Antwerp region where I lived until I finished my secondary school. Driven by a curiosity to the outer world and with help from the exchange programme AFS I lived for one year in Oruro, a colonial mining city in the Bolivian Altiplano. Back home this exchange year made me deciding to study ‘Tropical Landuse’ (ir.) at Wageningen University, Netherlands.


Eventually I lived about 11 years in Wageningen, interrupted by periods of living abroad. For half a year I lived ‘en brousse’ in Bénoué National Park, Cameroon, to study the feeding behavior of Hippopotamus and medium sized grazers such as Kobus kob. The awareness of the role of spatial patterns and dynamics in resource ecology made me enrolling into the Msc of  Geo-Information science. The Masters was completed with an internship in the nature reserve Montes Azules Biosphere Reserve of the Lacandon Jungle, Chiapas, Mexico, where I participated an expedition in search of agricultural Maya remnants. After finishing the MSc, my first job was mapping the aftermath of the 2004 Indian Ocean tsunami at the Laboratory of Geo-Information Science and Remote Sensing, which was followed by a PhD research at the same laboratory. The research was conducted in cooperation with Remote Sensing Laboraties (RSL) at the university of Zurich, Switzerland.


My PhD thesis focused on space-borne spectrodirectional estimation of forest properties. Among the optical Earth Observation instruments in space, one of the most innovative instruments is the experimental CHRIS-PROBA stellite. CHRIS is capable of sampling reflected radiation at five viewing angles over the visible and near-infrared (VNIR) region of the solar spectrum with a relatively high spatial resolution (~17 m). The added value of spectrodirectional (combined multi-angular and spectroscopy) data as measured by CHRIS for the benefit of forest monitoring was investigated. The studied forest was an Old-growth forest located in Swiss National Park.

I'm currently a postdoctoral researcher at the Laboratory of Earth Observation (LEO) group, which is part of the Imaging Processing Laboratory (IPL) at the University of València, Spain. My research activities are on one hand within the framework of ESA's FLuorescence EXplorer (FLEX) mission, and on the other hand focus on the retrieval of biophysical parameters. Between 2010 and 2012 I was funded by an EU Marie Curie IEF fellowship. Currently I work for FLEX project, e.g. PARCS, Photosynthesis Study and FLEX-bridge

I am the founder of the ARTMO (Automatic Radiative Models Operator) software package that has been developed together with Juan Pablo Rivera. ARTMO is a GUI software package developed in Matlab that provides essential tools for running and inverting a suite of radiative transfer mdoels, both at the leaf and at the canopy scale. ARTMO further provides several retrieval toolboxes.
