Qiaojie Xiong received undergraduate degree in biological science from University of Science and Technology of China. She then attended the Johns Hopkins University, school of medicine, where she received Ph.D. in Physiology. She was a postdoctoral fellow in Cold Spring Harbor Laboratory from 2008 to 2015. She joined the faculty of the Department of Neurobiology & Behavior at Stony Brook University in 2015.
My laboratory studies the neural mechanisms underlying auditory-guided behaviors.
Dorsal striatum is a key brain region in sensory-guided behaviors including decision-making
and learning. We initiated a series of investigations to determine how neural circuits
connecting the auditory striatum, a posterior sub-region of the dorsal striatum, regulate
auditory-guided behaviors including: 1) transformation from auditory cues to motor
action; 2) modulation of attention and vigilance states on auditory processing; and
3) learning induced changes in the circuitry that enable the association between auditory
cues and motor actions. We use interdisciplinary and state-of-the-art approaches including
rodent behavioral paradigms, in vivo and in vitro electrophysiological recordings,
in vivo calcium imaging, and chemogenetic and optogenetic techniques to arrive at
information about structure/function relationships that support auditory-cued behaviors
at their highest levels.
