1.MOLECULAR MODULATORS OF PHEROMONE PERCEPTION
We recently showed that chemosensory perception can have long term effects on fertility (Ng et al., Nat Comm, 2015). We are attempting to identify the downstream modulators that mediate this effect.
2.CHEMICAL DIVERSITY OF NATIVE HAWAIIAN DROSOPHILA
The Hawaiian Drosophila clade exhibit spectacular ecological and behavioral variation. We seek to characterize the chemical diversity of Hawaiian drosophilid cuticular lipids and pheromones using mass spectrometry and the influence of environmental and social factors. Transcriptomics will be used to examine the underlying biosynthetic pathways.

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