As an animal welfare attorney and co-founder of the nonprofit The Greenfield Project, Liz focuses on improving legislative, regulatory, industry, and corporate policies that impact farm animals and sustainable agriculture.

After receiving a B.A. in Biology magna cum laude from Harvard University, a M.Sc. in Developmental Psychology from Queen’s University, and a J.D. from New York University School of Law, Liz completed a year-long litigation fellowship at the Animal Legal Defense Fund (ALDF) and then went to work at Compassion Over Killing as their Director of Public Policy. Liz has a background in both animal law and environmental law and has worked at the environmental firm Meyer, Glitzenstein, and Eubanks as well as the Natural Resources Defense Council.

As a part of ALDF’s team, Liz garnered valuable litigation experience, including writing briefs, regulatory petitions, and policy papers. At COK, Liz focused on regulatory and policy initiatives in order to improve the treatment of farmed animals. She is also a frequent speaker at various events related to animals and food. 

Liz has also spent over five years as a laboratory manager and researcher studying psychology in a research setting, endowing her with a scientific approach that is uncommon and invaluable in the nonprofit sector. She has given lectures at scientific conferences, taught undergraduate classes, and run volunteer programs for elementary school children, giving her significant experience with educational outreach.
