Tom and Bonnie O'Brien worked at the University of Florida (Biochemistry & Molecular Biology, and Electron Microscopy, in the Interdisciplinary Center for Biotechnology Research) when they weren't traveling. Both are retired now, but Tom still teaches (more than before "retirement") and continues research on mitochondrial ribosomes.
