text: In 1957, Butt joined the faculty of physics at the Government College University, eventually becoming the lecturer in physics in 1958 and remained at his alma mater till 1961. He then taught physics at the University of Birmingham for several years and worked closely with British physicist, Dr. D. A. OConner, on the applications of diffraction, wave mechanics, and neutron scattering. Their work was sponsored and supported by the U.S. Department of Energy through the OSTI. Collaboration between Butt and OConnor established the scientific confirmation of Ivar Wallers Theory of Phonons at the Bragg diffraction peaks using the Mössbauer spectroscopy from LiFs single crystals. Their work has been extensively cited for several decades and printed in several books including those of Cambridge University Press and North Holland Publishers in the United Kingdom. He remained associated with the CERN in Switzerland and the International Center for Theoretical Physics (ICTP) in Italy where his work on solid-state physics was widely recognized.
  In 1973, Butt joined the faculty of natural science at the Quaid-i-Azam University and briefly taught a course on solid-state physics and taught courses on material science while supervised one of his students PhD thesis at the Quaid-i-Azam University. He also served on the examiner board for doctoral and masters thesis programs at the Punjab University and Bahauddin Zakariya University. He taught courses on physics at the Quaid-i-Azam University until 2000 when he joined the University of Oxford to teach physics.
  In 1973, Butt authored a college textbook, "Waves and Oscillation" that covers wide range of topics in wave mechanics, sound vibration, and theory of optics, which is extensively used by students in physics and mechanical engineering students in Pakistan. In 1996, he also authored a policy book, "CTBT & Its Implications".
