Biography

Dr. Fitzgerald is chief of the Biotherapy Section, Laboratory of Molecular Biology, in the NCI. He received his Ph.D. in 1982 from the University of Cincinnati Medical School, Department of Microbiology. The focus of his Ph.D. dissertation was the endocytic uptake of Pseudomonas exotoxin. He has a longstanding interest in bacterial toxins and their use as therapeutic agents.
