Elizabeth Marincola has made important contributions advocating for increased government resources dedicated to science and improved public education in science, and is an advocate of open access to the scientific literature, open scholarship and advancing research communication. Her 2013 TEDMED talk addresses the many issues facing science, technology and medicine (STM) publishers.
From 2013 to 2016, Marincola was Chief Executive Officer of the Public Library of Science (PLOS).
From 2005–2013, prior to becoming CEO of PLOS, Marincola was President and CEO of the Society for Science & the Public (SSP) and publisher of Science News and Science News for Kids. During her tenure at SSP, Science News received 2009 EXCEL Awards from the Society of National Association Publications (renamed later that year to Association Media & Publishing) for General Excellence and Most Improved Magazine. As President of SSP, Marincola served on the Advisory Board of the USA Science and Engineering Festival.
From 1991–2005 she served as Executive Director of The American Society for Cell Biology (ASCB) and publisher of Molecular Biology of the Cell. Under her leadership, ASCB received the 2004 Institutional Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring from the President of the United States. In 2004 Marincola was named by ASCB as the first Citizen Member of the Society (with the late actor and advocate Christopher Reeve).
Marincola served on the first National Institutes of Health PubMed Central National Advisory Committee from 2000–2003, on the Board of Directors for PLOS from 2005–2011, and as the first Chair of the Board of Directors of the Open Access journal eLife from 2012–2013 until joining PLOS. PLOS confirmed that she will be leaving from her position at the end of 2016. 
Marincola currently lives in Palo Alto, CA. She has three kids Jamie, Paula, and Rachel.
