Dr. Dana Campbell received her PhD in 2009 from the University of Auckland, New Zealand working in understanding species recognition and mate choice in captive zebra finches. She then completed 5 years of behaviour and welfare postdoctoral research fur-farmed mink at the University of Guelph (Canada), with laying hens in alternative housing systems at Michigan State University (USA) and with free-range laying hens at the University of New England (Australia). She is currently a Senior Research Scientist at Australia's national science agency, CSIRO (Commonwealth Scientific and Industrial Research Organisation). Dr. Campbell works in animal behaviour and welfare conducting both fundamental and applied research on a range of livestock species including laying hens, ducks, cattle, sheep, and prawns. In her research toward understanding how to measure and improve welfare, she is especially interested in understanding how animals adapt to their housing systems, the effects of rearing environments, effective enrichment, novel measures of affective state, and use of precision technology to obtain individual-level measurements. Dr.

Campbell's research has been used to inform updates of national standards and guidelines, assurance schemes, and legislation. Marisa Erasmus is an Associate Professor of animal behavior and welfare in the Department of Animal Sciences at Purdue University. Her research focuses on developing animal-based measures of welfare and examining the effects of environmental and management factors on animal behavior and welfare. She has a strong interest in interdisciplinary research that can help inform and guide management and welfare practices for farm animals. Her extension activities include working with the commercial poultry and livestock industries to understand and address animal welfare needs and providing educational resources about animal production and welfare. She serves on various scientific advisory boards and committees and has received awards for her research and extension work.
