Communication between scientists and animal technicians is considered important for creating a 'culture of care' in facilities that use animals in scientific research. For example, the Brown report, which investigated alleged failures of animal care at Imperial College London, noted the physical and social separation between animal technicians and scientists as a problem that delimited a culture of care. This paper seeks to better understand the communicative relationships between scientists and animal technicians in this context. We conducted a survey of scientists working in the UK who use animals in their research (n = 230), asking who they spoke with about various aspects related to using animals in research. We found that scientists communicated with technicians about operational issues, while they spoke with other scientists about experimental design as well as moral questions and concerns. We probe the meaning of these communicative relationships using narrative analysis of semi-structured, qualitative interviews conducted with consenting survey respondents (n = 14). Analytically, this paper seeks to bridge social network analysis with geographies of care through a shared concern with relations of power.Patrones comunicativos y redes sociales entre científicos y técnicos en una cultura del cuidado: discutiendo la moralidad a través de una jerarquía de espacios ocupacionales RESUMEN La comunicación entre científicos y técnicos en animales se considera importante para crear una 'cultura del cuidado' en las instalaciones que utilizan animales en la investigación científica. Por ejemplo, el informe Brown, que investigó supuestos fallos en el cuidado de los animales en el Imperial College de Londres, señaló la separación física y social entre técnicos animales y científicos como un problema que delimitaba una cultura del cuidado. Este artículo busca comprender mejor las relaciones comunicativas entre científicos y técnicos en animales en este contexto. Realizamos ARTICLE HISTORY
