In late 2008, I was given an assignment to take an environmental portrait of Robert Ghrist, a math professor who teaches in both the School of Arts and Sciences and the Engineering School at the University of Pennsylvania in Philadelphia.

The topic of n-dimensional space is an abstract and esoteric subject. My challenge in photographing Professor Ghrist was to find an environment that hints at spatial relationships.

The newest Penn Engineering building, Skirkanich Hall has a multitude of textures and colors. Working in collaboration with an art director for Penn, I spent time scouting, looking at several places in the building in which to shoot the portrait.

Below are alternate photographs taken during the shoot, including one with a model made with flexible rods that helps students visualize multi-dimensional spaces.
