Research Interests

Pheromones play an important role in the courtship ritual of *Drosophila*.
The predictable steps of the mating behavior can be used to map the genes and neural circuits that underlie pheromone detection.

The overall aim my research is to understand the evolution of pheromones (chemical communication cues). We use the vinegar fly Drosophila as a model system because of its spectacular biodiversity, quantifiable behaviors, and availability of genetic tools. In addition, we apply and develop mass spectrometry-based tools to characterize lipid pheromones. Our major interests are as follow:

  • Biodiversity of pheromones: characterizing the chemical diversity, function, and biochemical production of lipid pheromones amongst Drosophila species, including native Hawaiian Drosophila
  • Neural basis of pheromone detection: elucidation of the cellular and molecular mechanisms underlying pheromone detection and behavior
  • Methods for lipid pheromone analysis: development of improved mass spectrometry-based methods for lipid structural characterization and detection of pheromones from intact insects

We welcome collaborations with researchers interested in mass spectrometry instrumentation, organic synthesis, chemical ecology of other organisms, and ecology and evolution.
