Synaptic Vesicle Dynamics

The laboratory investigates the fundamental aspects of synaptic vesicle recycling related to neurological and neurodegenerative diseases using mouse and mammalian cells as a model system. Cutting edge genomic engineering is combined with the latest imaging and cell biological techniques to study the processes that regulate synaptic vesicle formation. In a distinct but related strand of work, we are exploring the signaling processes that arise from altered neurotransmission and lead to neurodegeneration.
