Nancy Tuchman (born January 17, 1958) is an American environmental scientist, educator, and activist. She specializes on human impacts on aquatic ecosystem function, with a focus on coastal Great Lake ecosystems. Tuchman is dedicated to raising public awareness about issues of global climate change and education. Her dedication is shown through her thirty years of educating students in environmental sciences at Loyola University Chicago. In 2013 she founded the Institute of Environmental Sustainability on Loyola University's campus - which later became the School of Environmental Sustainability in late 2020 - and is a driver of environmental change and progress in the Chicago area.

Early life and education 
Tuchman grew up in Ann Arbor, Michigan where she was raised for a love of the outdoors by two amateur ecologist parents. Time spent in nature, exploring streams and lakes, led to her passion for aquatic ecosystems that carried out through her education and career.

Tuchman went on to study biology and ecology at Central Michigan University to then earn a Masters of Science in aquatic ecology. From there she attended the University of Louisville to earn a Ph.D in aquatic ecology in 1988 with advisor, R. Jan Stevenson. Her dissertation was titled: “Effects of different intensities and frequencies of disturbance by snail herbivory on periphyton succession.”

Career and research 
Tuchman's research focuses on human impacts to aquatic ecosystems with three main lines of research: effects of invasive species on coastal ecosystems, effects of Greenhouse gases on stream ecosystem food webs, and the effects of contaminants and pharmaceuticals on streams and lakes.  She is currently examining the impacts of invasive species, Typha x glauca (hybrid cattail) and Phragmites australis (common reed) in the Great lakes coastal wetlands. Her team is now experimenting with economic and sustainable harvesting methods to remove the invasive plant species and use them as a biomass, as the cattail is high in cellulose-carbon- great for burning.

In 1988 she became an instructor in the biology department at Loyola University Chicago. Over 30 years of research, Tuchman has been awarded over $4.5 million in federal grants, she has authored or co-authored over 50 manuscripts and book chapters, and mentored or co-mentored over 100 undergraduate and graduate students in her lab. In 2002 she served as a program officer for the Ecosystem Studies Program at the National Science Foundation (NSF) to overseeing a $13 million dollar budget and two programs, Ecosystem Studies and Coupled Natural and Human Systems.

After serving at the NSF, she returned to Loyola as Associate Provost for Research and Centers. This position gave her headway for the discussion and proposing of the idea to make a more energy efficient and sustainable campus and ultimately establish the Institute of Environmental Sustainability. Tuchman has been a leader in the efforts to re-imagine Loyola's campus as green certified, as well as incorporating environmental education in the core curriculum for all undergraduate students. In 2016, Loyola University Chicago was named one of the seven greenest universities in the nation according to Sierra Magazine. The Institute of Environmental Sustainability at Loyola has hosted an annual Climate Change Conference since 2015. Tuchman believes that Jesuit universities can play an important role in the development of incorporating environmental education into higher education across the board because climate change is tied to issues of social justice.

From 2008 to 2010, Tuchman served as president-elect and then president of the Society for Freshwater Science.
