Within the Wildlife Management and Invasive Alien Species team, he specialized in rodent control.

In 2008 he founded the laboratory animal lab LA 1400559 at INBO. Through his role as experiment leader, secretary of the Animal Welfare Ethics Committee of INBO and as laboratory manager, he has built up special expertise over the past 20 years on the theme of animal welfare and laboratory animal science in relation to wild animals. Since 2022, Kristof has been a member of the Flemish Laboratory Animal Commission, an advisory board within the Flemish Animal Welfare Department.

For many years he has been a board member of the Belgian Wildlife Disease Association (BWDS), a de facto association that brings together people with an interest in wildlife diseases. He is co-organizer of a biennial international symposium on wildlife diseases.
