A central goal of my research is to identify the molecular pathways and matrix that shape the structure and strength of synaptic connections formed during development. Understanding the developmental plasticity and pre- and post-synaptic organization of synapses is crucial to illuminate the mechanisms by which neuronal circuits form and change in the healthy and diseased brain. Using Drosophila as a model system, we have identified mutants that show altered structure/function in the neuromuscular junction synapses. We are currently characterizing these mutants in the context of synaptic development. In addition, the powerful fly genetics has also been combined with biochemical techniques, especially tandem affinity purification of TAP-tagged synaptic proteins, to identify novel molecules that play structural or signaling roles in shaping the synapse.
 
Studies from our lab and many others demonstrate that ubiquitination and ubiquitin-mediated pathways play essential roles in not only protein quality-control and homeostasis, but also a multitude of other processes including protein trafficking, neuronal connectivity, synaptogenesis, synaptic transmission and neural degeneration. To understand these ubiquitin-mediated events in the brain, we combine the Drosophila genetics with comparative proteomics to analyze the difference of ubiquitination profiles between normal and degenerating fly brains. The goal is to identify specific ubiquitin targets in response to a particular pathological condition, especially age-related neurodegenerative diseases such as Alzheimer Disease and Parkinson's Disease. 
 

Research Interests

Keywords:
synaptic formation, structure and function; role of ubiquitination in neurodegeneration, synaptic development and plasticity.
 

We combine the powerful fly genetics with proteomic and biochemical approaches to understand the mechanisms underlying learning and memory, mental retardation, and age-related neural disorders, such as Parkinson’s Disease and Alzheimer’s Disease.
