Every year in the U.S., 200,000 people get pacemakers, 600,000 get knee replacements and 2.5 million have surgery to implant artificial eye lenses to fix cataracts. But the medical community knows little about how the aging process affects these implantable medical devices.

Bryan Brown wants to change that.

He’s a professor of bioengineering at the University of Pittsburgh, and he’s trying to figure out how to harness the immune system’s natural inflammatory response to better integrate these devices into the body.
