A nationally recognized expert in food safety and lead of a multi-institutional animal health and food security policy project, Dr. Sischo’s program integrates basic and translational research that across disciplines to affect policy change to improve animal and human health.

Dr. Sischo's research and teaching interests are at the intersection of animal agriculture systems and the rural, suburban and urban communities that interact with these systems. Understanding and supporting efficient, sustainable, and healthy food systems that promote food security and public health are major research interests.

Dr. Sischo's primary research is in:

  • Understanding the ecology of zoonotic and food-borne pathogens in animal production units, with a particular emphasis on the transmission dynamics of Salmonella across rural and urban interfaces.
  • The impact of communication and management on complex agricultural production systems on the use of antibiotics.
  • Describing interventions on dairy and beef operations that change the shedding patterns of shiga toxin Escherichia coli in adult and young cattle.
  • Understanding the significance of the cattle intestinal microbiome on health and productivity and particularly on changes to the microbiome that impact carbon cycles on animal production systems.
  • Developing quantitative models to predict the impact of policy and communication on disease transmission.

His interests are not only on the fundamental biology of the organisms but also their impact on the productivity of dairy operations and the marketability of dairy products. Much of Bill's work affects quality management strategies for dairy farms, including the development of risk assessments for practices with public health significance. Dr. Sischo's research and teaching has resulted in an active program to transfer research knowledge to inform agricultural, animal health, and public health policy and includes study sites in North America, West and East Africa, and South America.

Dr. Sischo is a faculty member in the Paul G. Allen School for Global Animal Health. He has created a multi-institutional, interdisciplinary program integrating the fundamentals of leadership, communication, and policy formulation to address the compelling issues that face our global animal health systems. In addition, he serves on the board of directors for Veterinarians Without Borders.
