The overarching goal of the research conducted in our lab is to understand a central question in neuroscience, which is at the core of information processing in all animals: How does a circuit of neurons translate olfactory input into behavioral output?
In our lab, we study olfaction since it offers a plethora of biological questions awaiting understanding at the molecular and cellular level. Specifically, we focus our work on the sophisticated (but numerically simple!) olfactory system of the fruit fly (Drosophila melanogaster) larva. We study this olfactory system using numerous interdisciplinary approaches, including electrophysiology, behavior, and molecular genetics. We have recently developed tools (strong, specific activators for individual ORNs and a novel behavioral paradigm that allows detailed characterization of larval navigation) that will allow us to carry out an unparalleled, systematic, and comprehensive dissection of the larval olfactory circuit.
Although basic research is the cornerstone of our lab, there are practical benefits to studying insect olfaction. Hundreds of millions of people, each year, suffer from diseases transmitted by insects. Billions of dollars worth of agricultural losses in Nevada and worldwide, are caused by insects. Many of these insects locate their human or plant hosts through olfactory cues. A better understanding of the principles of olfaction and neural circuit function will enable the design of pragmatic and environmentally friendly methods to curb the menace of disease-carrying insects (e.g. mosquitoes), and agricultural pests (e.g. Mormon cricket grasshopper). Additionally, our research seeks to define mechanisms that underlie neurological diseases in humans.
