Jeff Gearhart

M.S., Research Director, 

Jeff has worked for over 20 years on a wide range of environmental issues, including air quality, pollution prevention, life cycle assessment, consumer product testing, and green chemistry. 

For over 16 years, he has worked with the Ecology Center. Jeff has spearheaded numerous chemicals policy market campaigns, co-authored multiple peer-reviewed articles on toxics in consumer products, pioneered citizen science in the use of x-ray fluorescence technology for toxics testing in products, and developed the now internationally recognized product chemistry disclosure project and its extensive website of robust advocacy resources and product testing results for more than 100,000 products. Jeff likes to create and build things, and it is this compulsion that drives him to develop campaigns that gather and present new knowledge so the world will have better products and an improved environment.

Jeff is assisted by numerous student interns to achieve the work of the program, providing critical exposure for young people to cutting edge technology for chemical testing.
