Elisabeth Adkins Marnik, PhD, is a scientist turned public science communicator whose mission is to make science and public health clear, compassionate, and relevant to everyday life. Raised in a home that deeply distrusted science and medicine, she first encountered real science as a junior in high school. That transformative moment now fuels her belief that science is meant to serve people and that communication and access determine whether that service reaches everyone. Trained as a geneticist and immunologist, Liz brings more than a decade of research and teaching experience to her work making complex ideas understandable and useful.

As Executive Director of The Evidence Collective, she leads national efforts to translate evidence into accessible, responsible public communication and to support independent voices working at the intersection of science, health, and policy. Her work focuses on building trust, countering false information, and ensuring communities have access to science they can use in their daily lives. As Chief Scientific Officer for Those Nerdy Girls, she helps shape evidence-based communication for world-wide readers, emphasizing empathy, clarity, and trust-building in the face of false information. Through Science Whiz Liz, she creates accessible content that makes science feel human and empowering. Liz’s work has been featured on Science Friday, HuffPost, and other media outlets, and she was named to Mainebiz’s 2025 “40 Under 40” list for her leadership and public impact.
