Professor Walter works in two areas: 1) explaining relationships between mathematics and environmental subjects, and how each can be used to educate the public about the other -- as exemplified in the 2011 book (and second edition to appear 2020), ``Mathematics for the Environment,'' and in the article on ``Earthquakes and Weatherquakes: Mathematics and Climate Change'' published in the November 2010 issue of the Notices of the American Mathematical Society; and 2) order structures, operators algebras, group duality, and group representation theory.
