extensionist
An extensionist is a professional who works to extend knowledge and practices, typically in fields like agriculture, public health, or community development. Their primary role is to bridge the gap between research institutions or experts and the end-users of that knowledge, who might be farmers, community members, or other practitioners. Extensionists facilitate the dissemination of new techniques, technologies, and information through various methods such as workshops, demonstrations, consultations, and the distribution of educational materials.
The work of an extensionist often involves understanding the specific needs and challenges of the target audience.
