The Gradinaru Lab studies the mechanism of action for deep brain stimulation (DBS), a therapeutical option for motor and mood disorders such as Parkinson’s and depression. Our previous work highlighted the importance of selectively controlling axons and not local cell bodies in modulating behavior, a principle that might play a generalized role across many effective deep brain stimulation paradigms. We are now particularly interested in the long-term effects of DBS on neuronal health, function, and ultimately behavior.

In addition, the lab continues to push forward optogenetic technologies by developing tools for electrical and biochemical control and localizing them to subcellular compartments. To achieve the goals of neuronal circuits investigation and tool development for neuroscience the Gradinaru lab uses advanced Molecular and Synthetic Biology; Electrophysiology (in vitro and in vivo); Behavior; Imaging (2-photon), Optogenetics (gene delivery of photosensitive proteins to specific cell types) and CLARITY (slicing-free whole brain imaging and molecular phenotyping).

Gradinaru Lab is a great fit for any interdisciplinary-minded person. Projects in the lab range from studying the impact of neuromodulation on neurodegeneration and behavior to engineering needed tools (molecular, cellular, hardware) for neuroscience research.
