Molecular Biogeographic Analysis of the Relationships Between Papilio indra Sub-Species
I currently collaborate with Dr. Wayne Whaley to study the evolution and population dynamics of the Indra Swallowtail Butterfly Papilio indra. I provide UVSC undergraduates with opportunities to become involved in this research. We extract DNA from butterfly specimens, amplify specific fragments, sequence the fragments, and compare their sequences to make inferences about the relationships between different populations of butterflies and how long they have been isolated from one another.
In the past, I have studied the role of tyrosine kinases and tyrosine phosphatases in the development of the fruit fly, Drosophila melanogaster, using two main approaches. First, I have used genetic methods to identify genes that interact with the Drosophila EGF receptor homologue (DER). These genes may help us understand how stimulation of the DER leads to a variety of different responses depending on the type of cell or tissue that is involved in the response.
A second emphasis of my past research has been to use molecular methods to isolate fragments of protein tyrosine phosphatase (PTP) genes that are expressed in the Drosophila ovary. My coworkers and I determined the time and locations of expression of these genes in the ovary. These studies may help us understand the roles of these PTPs in oogenesis.
I also have training in the areas of Molecular Biology and Nucleic Acid Biochemistry. My Ph.D. research involved the mechanisms of RNA catalysis.
