My laboratory studies the molecular and cellular mechanisms that control the diverse physiological roles of glial cells in the central nervous system.
Our studies concentrate on two emerging areas in the neurosciences: astrocyte control of brain circuits and cancer neuroscience of brain tumors. Our investigations into brain circuits focus on the lines of communication between astrocytes and neurons that drive circuit function. These studies identified functionally distinct astrocyte subtypes and region-specific transcription factor codes that oversee circuit function in the hippocampus, cortex, olfactory bulb, amygdala, and spinal cord. We extended these studies towards experience-dependent astrocyte plasticity, identifying new cellular, transcriptional, and epigenetic mechanisms governing astrocyte adaptation to a host of experiences, including learning, sensory, depression, and sleep
In the brain tumor space, my lab developed several autochthonous mouse models of glioma that we combined with high-throughput, in vivo functional genomics screens to uncover how brain tumors remodel the neuronal microenvironment towards hyperactivity. Our work in the cancer neuroscience of brain tumors has uncovered circuit-specific effects on brain tumor pathogenesis, while identifying bi-directional signaling mechanisms between tumors and neurons that drive malignant progression and hyperactive brain states.
