Education and career
Lowell S. Brown earned his A.B. in physics from the University of California, Berkeley in 1956 and his Ph.D. in physics from Harvard University in 1961, with a National Science Foundation Predoctoral Fellowship, studying quantum field theory under Julian Schwinger.
After National Science Foundation Postdoctoral Fellowships at Istituto di Fisica Dell'Universita in Rome and at Imperial College of Science and Technology in London, Brown joined Yale University as an Associate Professor through 1968. For most of his career, Brown served as a Professor at the University of Washington (1969-2001). Then, he was a Staff Scientist at Los Alamos National Laboratory in New Mexico (2001-2014). He is now a Guest Scientist at Los Alamos.
Brown again visited Imperial College in 1971-1972, continuing his research with a National Science Foundation Senior Postdoctoral Fellowship. He was awarded a John Simon Guggenheim Memorial Foundation Fellowship in 1979 and undertook his research at the European Organization for Nuclear Research (CERN), Geneva, Switzerland, and the Institute for Advanced Study, Princeton, New Jersey.
His book "Quantum Field Theory" (1994) has been well received. Pierre Ramond's review in Science states that Brown's book is "marked by its astute choice of topics as well as by the clarity with which they are expounded, it is akin to a toolbox for students of modern quantum field theory... a very thorough and rare treatment…a very interesting and original textbook. I strongly recommend this book to whoever aspires to become either a particle or a condensed matter physicist."
Brown's work on the interaction of intense laser beams with electrons (Brown & Kibble 1964) is still cited forty or so years later.
In astrophysics and general relativity, his work on the stress-energy tensor of various fields coupled to an arbitrary classical gravitational field (1977) is noteworthy: it uses the method of dimensional continuation and proper time representations, and with these methods, he computed the unique gravitational anomaly for scalar fields and the anomaly for vector fields (Brown & Cassidy 1977).
Brown and collaborators computed the energy-energy correlation in electron-positron annihilation (Basham et al. 1978), which provides one method of measuring the strong interaction QCD coupling constant.
At the University of Washington, Hans Dehmelt captured single charged particles in very stable orbits in a Penning trap. This arrangement, called geonium, enabled measurement of the magnetic moment of the electron with exquisite precision for which Dehmelt won the Nobel Prize. Brown became fascinated with this new experimental procedure and with coworkers wrote many papers investigating the detailed workings of geonium. His work culminated in a long review article (Brown & Gabrielse 1986) that has become a handbook for other experimenters who use a Penning trap.
Brown also investigated plasma effects on nuclear fusion (Brown & Sawyer 1997), wrote a paper applying field theory to plasma physics (Brown & Yaffe 2001), obtained the non-leading corrections in plasma stopping power (Brown et al. 2005), and provided an effective field description for deuterium-tritium fusion (Brown & Hale 2014).

Professional society activities
Brown served on many committees of the American Physical Society and was the first academic Editor of Physical Review D. During his tenure (1987-1995), he was instrumental in incorporating author-prepared electronic manuscripts into the journal’s editorial and publishing process, and he conceived and promoted an early version of the electronic status inquiry system for authors.
