Mitochondria are the cell's powerplants, turning energy from food into energy our bodies use, so problems with their function are serious. University of Iowa researcher Dr. Rhonda Souvenir studies these illnesses. She earned her doctorate in microbiology and molecular genetics from Loma Linda University and came to Iowa with another black scientist, Dr. Dale Abel, after working with him as a postdoctoral researcher at the University of Utah. Both are now on a list of 1,000 inspiring black scientists. This University of Iowa feature describes her journey from Guyana to the Hawkeye State.
