Contributions
Rufus integrated the McMath-Hulbert Observatory and was known for his contributions to the history of astronomy in America. His principal research work in astronomy focused on Asteroseismology, relating to atmospheric circulation in stars of variable density and spectroscopic analysis of the composition of stars. He was one of the earliest research scholars to contribute to the new theory of Cepheid variables stars and in Stellar pulsation.

As a member of the University of Michigan's committee on Barbour scholarships, Rufus aided a large number of women students from East Asian countries.

Books
Rufus was the editor of Johann Kepler, 1571–1630: A Tercentenary Commemoration of His Life and Work (History of Science Society, 1931).
