Professor David Wilson has spent his career studying things we can't see. His research at Case Western Reserve University focuses on cutting-edge bio-imaging technology.

Advancements in this technology could mean big changes in the way some diseases are detected and treated. ideastream's Eric Wellman spoke with Professor Wilson about this technology.
