MR. ROBERT E. JOHNSON
Ph.D., University of Wisconsin-Eau Claire
John L. Newcomb Professor of Materials Science and Engineering
School of Engineering & Applied Science 1971 ~ 2019
A theoretical physicist and mathematician from
the University of Wisconsin, Bob Johnson joined
the University’s engineering physics faculty as
an assistant professor in 1971, received tenure
in 1977, and served as Assistant Dean of the
School of Engineering & Applied Science from
1982 to 1985. The dawn of the Space Age
inspired Johnson to consider the impact of
solar radiation on airless planetary surfaces
and the development of atmosphere, and he
retires with nearly 50 years of service at UVA,
having worked in both the Materials Science
and Engineering and Astronomy departments.
A founder of the computational planetary
science field, Johnson developed mathematical
methods and collaborated on synergistic
experimental laboratory work with scientists
at UVA, Bell Laboratories, Uppsala University, Catania University, and NASA
Goddard to predict the physical and chemical phenomena of our solar system. His
manifold contributions to planetary astronomy include models of the erosion of ices
by magnetospheric ions on Galilean satellites, charge-transfer between icy grains
in Saturn’s rings, exospheric production on the Moon and Mercury, Voyager image
analysis of Europa, and darkening on Pluto. Johnson revolutionized understanding
of Saturn and its environs and was an integral member of NASA’s Cassini Mission,
honored with the NASA Award for Outstanding Contributions to the Mission in
2008. Johnson headed UVA’s Engineering Physics Graduate Program for 25
years, mentoring students with interests in astronomy, space physics, biophysics,
materials science, and detector development. His students and postdocs hold
significant positions at NASA, the Jet Propulsion Laboratory, Johns Hopkins
Applied Physics Laboratory, to name only a few. Johnson has published over 350
scientific publications, has authored two seminal graduate-level textbooks, and is
currently completing a third book.
For many years, Bob taught popular undergraduate courses in Applied
Mathematics, earning the affectionate nickname “Space Bob,” and has been
inducted into the (semi-secret) Society of P.R.I. by his students. Always generous
with his time and energy, Bob continues to mentor his students and colleagues,
also providing motivation for art pieces created by artist Barbara MacCallum,
his wife. After retirement, he plans to enjoy time with his family, splitting his time
between Charlottesville, Maine, and New York.
