Dr. Trounce gained his PhD degree from the University of Melbourne in 1991. He held postdoctoral and junior faculty positions at Emory University, Atlanta, in the laboratory of Douglas Wallace before establishing his own laboratory in Australia in 1997.
He is currently Associate Professor in the Center for Eye Research Australia. His expertise is in oxidative phosphorylation, mitochondrial genetics, cell biology and neurobiology. He has made contributions toward understanding mitochondrial disease genetics and oxidative phosphorylation dysfunction, age-related mitochondrial decline, mouse modeling of mitochondrial disease and cybrid modeling of mtDNA diseases. His focus has turned in the past 10 years to mitochondrial contributions to age-related neurodegenerative retinal disease, especially glaucoma.
