This is what occurred to me.

I suspect that the "traverse" is back to the good old "multidisciplinary" and that all they are saying is that he enjoys wandering from one speciality to another, refusing to acknowledge the boundaries between things that are very different.

You could even say he enjoys wandering in and out of different and apparently incompatible fields

this way you still have a -tenuous- transport theme, perhaps preceded by little-used/trod...

Fellow adventurers John Coltrane and John Foxx would approve. :-)

Not a literal translation, but a formulation often used in academia. Just a suggestion, certainly not the only way to say it:

The Department of History of Art and Architecture at Harvard University offers the broadest range of courses available in North America today. The faculty offers courses covering the diverse historical and cultural geographies of the world—as well as their points of intersection, dialogue, and exchange—in the fields of African, American, Ancient (Near East, Greek, and Roman), architectural history and theory, Baroque and Rococo, Byzantine, Chinese, Indian, Islamic, Japanese, Latin American/Pre-Columbian, Medieval, modern and contemporary, photography, and the Renaissance (Northern and Southern). The scope of art and architecture studied is matched in variety by both approaches and methods of study.
