Murray V. Johnston III

What’s really important when you get down to thinking of global climate, and how could these measurements affect you?


Murray V. Johnston III is a professor of chemistry and biochemistry at the University of Delaware. His research focuses on applying mass spectrometry to determine changes in matter, specifically related to problems of atmospheric, environmental, and biological significance.

Instruments like mass spectrometers are an important method by which scientists can study changes in the air at the most minute levels, even the level of nanoparticles. While we can’t see all the changes in the air that might affect things like cloud formation or climate, Johnston’s research provides us with a fundamental understanding of particles in the air and the various factors at work that change how particles form, react, and behave.
