Copper plays an essential role in human physiology. It serves as a cofactor to key metabolic enzymes that are required for respiration, neurotransmitter biosynthesis, detoxification of radicals, blood clotting, connective tissue formation, and many others processes. Through currently unknown...

We are interested in the structure and function of the Golgi complex, a ubiquitous eukaryotic organelle that plays a central role in post-translational processing and sorting of newly synthesized proteins and lipids in the secretory pathway. The Golgi complex...

Neurotransmitter receptors mediate signal transduction at the postsynaptic membrane of synaptic connections between neurons in the nervous system. We have been studying the molecular mechanisms in the regulation of neurotransmitter receptor function. Recently we have focused on glutamate receptors,...

Regulation of Sterol Homeostasis Elevated serum cholesterol is a primary risk factor for heart disease. A negative feedback mechanism prevents excessive cellular cholesterol accumulation by regulating SREBP, a membrane-bound transcription factor that activates genes required for cholesterol biosynthesis and...

My lab studies the cellular and molecular basis of synaptic transmission and plasticity. Neuronal signaling events at synapses determine circuit responses and result in specific behavioral outputs. This signaling is dynamic – modulated by synapse activity history and perceived...

Research topics: Cryo-electron microscopy, membrane proteins, glutamate receptors, protein homeostasis We are interested in the structural and biochemical underpinnings of neurotransmission and neurodegeneration, as well as the homeostasis of the proteins contributing to these processes. Primarily, we will be...

Motor neurons are some of the largest cells in the human body, with axon lengths up to a meter long. This large size of motor neurons and muscle cells makes them particularly vulnerable to disruptions of intracellular trafficking with...

The central theme of my research is to understand how mechanical actions feedback to biochemical pathways in cellular processes, and how such mechanochemical crosstalk among key cellular players governs spatial-temporal regulation and shapes cell functions. I confront these challenges...
