For his undergraduate diploma work, Müller studied under G. Busch.
He worked on the Hall Effect in gray tin, a semimetal.

Between his undergraduate degree and beginning his graduate studies, he worked for one year in the Department of Industrial Research at ETH on the Eidophor large-scale display system.

At IBM his research for almost 15 years centered on SrTiO₃ (strontium titanate) and related perovskite compounds.
He studied their photochromic properties when doped with various transition-metal ions; their chemical binding, ferroelectric and soft-mode properties; and the critical and multicritical phenomena of their structural phase transitions.
Important highlights of this research have been published in a book written together with Tom Kool from the University of Amsterdam (publisher: World Scientific).
