In mathematics, he worked in the areas of [[Wikipedia:Galois theory|Galois theory]] and [[Wikipedia:Monstrous moonshine|Moonshine theory]].

In music theory, he introduced [[Wikipedia:Exterior_algebra|wedge products]] as a way of classifying [[Regular_Temperaments|regular temperaments]]. In this system, a temperament is specified by means of a [[Wedgies_and_Multivals|wedgie]], which may technically be identified as a point on a [[Wikipedia:Grassmannian|Grassmannian]]. He had long drawn attention to the relationship between [[Equal_Temperaments|equal divisions of the octave]] and the [[The_Riemann_Zeta_Function_and_Tuning|Riemann zeta function]].[[#cite_note-1|[1]]][[#cite_note-2|[2]]][[#cite_note-3|[3]]] He [http://www.webcitation.org/67ZUSajSK early on] identified and emphasized free abelian groups of finite rank and their homomorphisms, and it was from that perspective that he contributed to the creation of the [~~http://x31eq.com/paradigm.html~~ regular mapping paradigm].

In the 1970s, Gene experimented with musical compositions using a device with four square-wave voices, whose tuning was very stable and accurate, being controlled by a [[Wikipedia:crystal oscillator|crystal oscillator]]. The device in turn was controlled by [[Wikipedia:HP 9800 series desktop computers|HP 9800 series desktop computers]], initially the HP 9830A, programmed in HP Basic, later the 9845A. Using this, he explored both just intonation with a particular emphasis on groups of transformations, and [[pajara|pajara]].
