I utilize the fruit fly (Drosophila melanogaster) in my research as a genetic model organism and have two major projects in my laboratory. 

First, I study Parkinson's disease (PD) in the fly and try to determine how to treat it.  We have recently found that phenotypes (symptoms) in a fly model of PD can be improved or even rescued when treated with nicotine (Chambers et al.).  We do not know how nicotine does this, but it has been found to be neuroprotective in other PD models.  Understanding how and why nicotine ameliorates the PD phenotype in our model is a current avenue of research. I collaborate with Dr. Lori Buhlman on this project.

Second, I have been studying the effects of anesthesia in the fly in an attempt to determine the molecular mechanism of commonly used clinical anesthetics.  In this process, we have found that CO2, the most common anesthetic used in flies, has long-term detrimental impacts on behaviors (Bartholomew et al.).  This is important, because it is possible that many researchers across the world utlize CO2 anesthesia without any regard to the effects it might have.  We are pursuing this effect and attempting to determine its mechanism.  I collaborate with Drs. Michael Quinlan and John VandenBrooks on this project.
