Research interests

Key words: Trigeminal system, Blink circuits, Oro-facial behaviors, Visual motor system, Gaze circuitry, Eye-head coordination, Somatosensory system, Thalamic spatio-temporal coding circuits, Complex tactile pattern coding

My research interests center around three broad areas:

  • The trigeminal system circuitry underlying the interplay of discrete sensory contributions arising from face, muscles and oral cavity that contribute to coordinated oro-facial behaviors including blinking, chewing, swallowing and speech production\
  • In conjunction with a colleague, visual motor system premotor circuitry underlying gaze and eye-head coordinated movements
  • The somatosensory system circuitry underlying object feature recognition (size, shape texture, motion) particularly in the sensory thalamus and primary sensory cortex. My research program takes a multifaceted approach combining varied anatomical techniques (tracers, viral vectors), extracellular recording and stimulating physiological techniques, together with several animal models (monkey, cat and mouse). The goal of this laboratory is to gain a better understanding of the components of neural circuits contribution to a wide array of stereotypic behaviors including orofacial behaviors and eye-head movements
