Research:

Genetics of transposable DNA in Drosophila and natural populations

   

Research Interests:

Cytogenetics, oncogenetics, radiation genetics and chromosome evolution. I am working on cytogenetics and phylo-genetics of Hawaiian Drosophila by analysis of polytene and metaphase chromosomes, and by DNA in situ hybridization. Recently, I have become interested in problems involving genetic organization of genomes, and the role of heterochromatin as a mechanism of chromosomal rearrangements. I will continue to study the puffing patterns of polytene chromosomes and their modification as examples of gene expression during development, and as a bioassay for mutagens, carcinogens and teratogens. I am conducting research work on sister chromatid exchange analysis and a study of effects of air pollutants on genetic materials. I use Drosophila, plants, Chinese hamsters, and human chromosomes as research tools.
