Background

Thomas D. Fox, a Professor of Genetics, is a member of both the Graduate Field of Genetics and Development and the Graduate Field of Biochemistry, Molecular and Cell Biology. He received his B.S. degree from Cornell University in 1971 and his Ph.D. in Biochemistry and Molecular Biology from Harvard University in 1976. He received a Helen Hay Whitney Foundation Fellowship to do postdoctoral research at the Biocenter in Basel, Switzerland. Following his postdoctoral work he remained at the Biocenter as a faculty member in the Department of Biochemistry until coming to Cornell in 1981 to join the Section of Genetics and Development.

At Cornell he received a Dupont Young Faculty Award, a Research Career Development Award from the National Institutes of Health, and the State University of New York Chancellor's Award for Excellence in Teaching.  He has served as a member of the National Institutes of Health Biochemistry Study Section. Dr. Fox is an Associate Editor of Molecular Biology of the Cell. He is a member of the American Academy of Microbiology, the American Society for Microbiology, American Society for Biological Chemists, the Society for the Study of Amphibians and Reptiles and the Genetics Society of America.

Research Description

The development of mitochondria involves interaction of genes and their products from both the nucleocytoplasmic and the mitochondrial genetic systems. Yeast (Saccharomyces cerevisiae) is a very favorable organism for the study of these gene interactions, since mutations in both genetic systems can be isolated and manipulated. Furthermore, genetic transformation and homologous recombination allow the replacement of wild-type by mutant, or novel, DNA sequences in both the nuclear and mitochondrial genomes. more
