Steven Roche

Director and Principal Consultant

As the founder of ACER Consulting, Steven believes in conducting health research through a one health lens, and aims to mobilize research in creative ways to improve health and prevent disease. His interdisciplinary skill set blends epidemiological research, agricultural extension, and health promotion methodologies to understand and influence health outcomes. He has extensive experience conducting applied epidemiological research and designing, implementing, and evaluating knowledge mobilization programs and tools for industry, academic and government stakeholders in the agri-food and public health sphere. ACER Consulting is driven by his passion for understanding health and disease, and innovating dissemination strategies to effectively mobilize quality research to improve disease prevention and control, food safety, and population health.

Steven received his PhD in Epidemiology from the Department of Population Medicine at the Ontario Veterinary College, University of Guelph. His doctoral research focused on the development, implementation, and mixed-methods evaluation of novel communication and extension approaches to improve the adoption of on-farm management practices to control Johne’s disease in the Ontario dairy industry. Steven also holds a MSc in Epidemiology and BSc in Zoology from the University of Guelph. Through his formal training and applied research experience, Steven is a well-rounded researcher equipped with the skill set, drive, and collaborative spirit to help a diverse range of clients understand, inform, and influence.
