Research Interests:

My main project involves examining the role of BMP signaling in learning and memory. BMP signaling components are known to be expressed in a region of the brain called the hippocampus, which is thought to be heavily involved in learning and memory in mammals. To investigate this, I perform various behavior tests in different strains of BMP mutant mice. Some tests I use include the Morris water maze to assess spatial learning and memory, as wells as tests of cognitive function such as novel object recognition.

The other project I work on in the lab involves the study of developmental timing in Drosophila melanogaster. I study the role of prothoracicotropic hormone (PTTH) during the final larval instar using different transgenic fly strains. PTTH is thought to regulate the production and/or secretion of ecdysone, a steroid hormone that stimulates molting and metamorphosis in Drosophila.
