Prior to coming to USC, Armstrong was dean of the school of arts and sciences from 1987 to 1993 at the Johns Hopkins University. He arrived at Johns Hopkins in 1969 and rose through the faculty ranks, attaining the rank of professor of physics in 1975. He served as chair of the department of physics and astronomy from 1984-1987.  His research spanned many fields of atomic and optical physics, including relativistic effects in atoms, group theory, new computational approaches to atomic structure, nonlinear interactions between intense optical fields and atoms, and chaos theory.

Armstrong received a B.S in physics from MIT in 1962 and a Ph.D. in physics from the University of California at Berkeley in 1966. Following graduation, he was a post-doctoral fellow at the Lawrence Berkeley Laboratory (1966-67).

During the period 1981-1983, Armstrong took leave from Hopkins in order to serve as in the dual roles of Program Officer for Atomic, Molecular, and Plasma Physics and Program Officer for Theoretical Physics at the National Science Foundation. He later served on the NSF Advisory Committee for Physics (1985-88), and as a member of the Committee of Visitors of the Physics Division of the NSF (1991).

Armstrong has served on a large number of boards and committees of the National Academy of Sciences/National Research Council, including the Committee on Recommendations for the U.S.Army Basic Scientific Research (1984-87), the Committee on Atomic and Molecular Sciences (1984-89, Chair 1985-88), and the Board on Physics and Astronomy (1989-96, executive committee 1993-96). He served on the Advisory Board of the Institute for Theoretical Physics in Santa Barbara (1992-96, chair 1994-95), of the Institute for Theoretical Atomic, Molecular and Optical Physics at Harvard (1994-97), and the Advisory Board of the Rochester Theory Center for Optical Science and Engineering (1996- 98, chair 1997-98).

Armstrong has also served on the boards of directors of the California Council of Science and Technology (1994-2005), the Southern California Economic Partnership (1994-2000), the Pacific Council on International Policy (1996-2005) and the Pacific Century Institute (2009- 2013). He was a member of the Council on Foreign Relations (2001- 2019). 

He was on the Board Advisory Committee on Education for Laureate, Inc (2015-2020), the Advisory Board of InsideTrack, Inc.(2006-2017), the Advisory Board of Fidelis, Inc. (2010-2016), and the Board of Trustees of Altius Education, Inc. (2010-2014).
