Research Interests
A major question in developmental biology is how a complex multicellular organism arises from a single egg. For most developing organisms, the process is initiated by first making very simple developmental decisions (such as deciding which end of the embryo will become the head). In the fruit fly Drosophila, the basic body pattern of the embryo is determined by the organization of the unfertilized egg. My lab is very interested in the means by which eggs become organized, and how the egg is constructed so as to support development. We are studying the role of a gene called mini spindles in oogenesis. Mini spindles encodes a protein that appears to be necessary for organizing and regulating microtubules. Research in the lab uses a variety of genetic and cell biology techniques, including antibody staining, fluorescence microscopy, genetic analysis, and computer image acquisition and analysis.
