Michel Callon is a French sociologist known for his work in the field of science and technology studies (STS). He is particularly recognized for developing the concept of "actor-network theory" (ANT), which explores how various actors, both human and non-human, interact and influence each other within networks. This approach emphasizes the importance of understanding the relationships and dynamics that shape scientific and technological developments. Callon's research often focuses on the role of economics, innovation, and public engagement in shaping societal outcomes. He has contributed to discussions on how knowledge is produced and the implications of this process for policy-making and governance. His work has had a significant impact on the understanding of the interplay between society and technology.
