Belgian, DVM, PhD – Guy (1960) graduated as doctor in veterinary medicine in 1985 (Gent, Belgium) and has over 25 years of experience in the field of spatial epidemiology, livestock geography and decision support systems. In the first part of his career (1987-2000) he completed a subsequent series of long-term resident assignments in Africa, first in Rwanda (VVOB) and then in Tanzania, Togo and Burkina Faso (FAO), combining research with development activities. His main research activity was the development and implementation of country wide Geographical Information Systems (GIS) applied to integrated vector borne disease control. In 1997 he was laureate of the National Academy of Overseas Sciences (Brussels, Belgium) with a dissertation on this topic. In 1999 he obtained his PhD on the design of a geo-referenced decision support methodology towards trypanosomiasis management in West Africa. He was one of the first to use remote sensing to model vector, pathogen and disease, and to integrate this information into a nation-wide GIS for veterinary decision support. Back in Europe he created Avia-GIS in 2001 to help bridge the gap between research and decision making in the field of spatial decision support systems applied to animal and public health, as well as plant pests. Guy is CEO of Avia-GIS. In recent years he developed a particular interest in understanding spatial patterns in the lifecycle of vector-borne diseases within the wider context of global change including: not only climate driven change, but also, and maybe more importantly, the increased global traffic of persons and goods, as well as land-use, land-cover and socio-economic changes. He is member of the board of Vétérinaires Sans Frontières (VSF-DZG) Belgium and secretary of the Flemish Society for Veterinary Epidemiology and Economics (FSVEE).
