Animal Welfare Scientist
Shannon is an Animal Welfare Scientist within the Animal Welfare Science Program at Lincoln Park Zoo. She has a background in mammalogy, behavioral ecology, and science communication. Shannon contributes to our zoo-wide welfare assessment program, and strives to develop novel evidence-based welfare assessments for species that have been historically understudied. She also seeks to improve our understanding of the complex relationship between zoo-housed animals and their environment, with the ultimate goal of enhancing the welfare of the animals while simultaneously providing zoo visitors with an enriching and educational zoo experience.
Prior to joining Lincoln Park Zoo, Shannon earned her Ph.D. in Integrative Biology from the University of California, Berkeley. She conducted her graduate work on the natural history and behavioral ecology of subterranean rodents from South America.
