Research interests:
I study the interactions between brain energy metabolism and neuronal signaling. This includes determining how different brain cells may use alternative energy fuels to glucose, such as lactate and ketone bodies, and how glutamatergic signaling affects mitochondrial motility. I use immunohistochemical methods (electron microscopy, confocal microscopy and western blotting), organotypic slice cultures and time-lapse fluorescence imaging in conjunction with patch-clamp recording.
