I did a quick Google and found him at:
https://www.weber.edu/performingarts/shannon_roberts.htmlThe working paper at the time was called "Global Relative Dissonance Theory" or something to that effect. I think I'll drop him a note and ask about it. My hunch is that it didn't see much interest outside of the school (University of Utah at that time), but I also more or less left any academic music pursuits around that same time so I just might not be in the know.
