Excitotoxic Loss of Post-Synaptic Sites is Distinct Temporally and Mechanistically from Neuronal Death

University of St. Thomas, BS Biochemistry and minor in Mathematics 2002
Graduate Research Description:
I am interested in studying synaptic changes that occur during excitotoxic-induced neuroegeneration. Excitotoxicity is caused by the excess release of glutamate and is thought to contribute to many neurodegenerative disorders including stroke, HIV associated dementia and Alzheimer's disease. I have developed a technique to track synaptic changes along with cell viability of single neurons over time. This has given us insights into the temporal relationship as well as mechanisms of synapse loss related to cell death.
