They studied the cell biology of Wolbachia in the germ line tissues of Drosophila melanogaster. As a postdoc in the laboratory of Daniel Barbash at Cornell, Ferree investigated the genetic basis of hybrid incompatibility between two fruit fly species. They found that a species-specific region of heterochromatin from D. melanogaster causes hybrid lethality when present in hybrids containing maternal cytoplasm from D. simulans. As a faculty member at the Claremont Colleges, Ferree studied several different systems, including lethal effects of circularized sex chromosomes, host-symbiont interactions underlying male killing caused by Spiroplasma bacteria in the fruit fly, and most recently, the molecular basis of genome elimination caused by a selfish B chromosome in the jewel wasp, Nasonia vitripennis.PublicationPSRs: Selfish chromosomes that manipulate reproductive development (https://www.sciencedirect.com/science/article/abs/pii/S108495212400020X)
