Research Interests:

The Sensory Neuroscience, Attention, and Perception Laboratory (SNAP Lab) aims to understand how our momentary behavioral goals are translated into neural signals that determine which sensory items are selected and which are ignored. More generally, how do attention brain mechanisms guide our behavior? In answering this question, we investigate both how perceptual objects are assembled by sensory systems, and how attention selects these objects for later processing by memory & motor systems. We adopt a systems-level neuroscience approach in which multimodal brain imaging techniques are integrated with psychophysical methods, computational modeling, and clinical populations. However, all work conducted in the SNAP Lab is firmly grounded in behavioral effects. Functional brain imaging methods used in the lab combine both correlative (fMRI) and interference (TMS, neuropsychology) methods to identify brain networks and test the causality of individual nodes, respectively. We also examine the structural connectivity of these brain networks using Diffusion Spectrum Imaging (DSI).

Examples of some of our current research projects include: 

  • Functional and structural connectivity between attention mechanisms in the parietal lobe and visual cortex in the occipital lobe, using TMS, fMRI, and DSI.
  • Behavioral and neural investigations of object-based selective attention.
  • Determining how Gestalt perceptual grouping principles give rise to visual object perception.
  • Exploring how auditory scene analysis cues affect auditory object perception.
  • Examining the role of attention in advertising.

I am currently interested in taking new Ph.D. students and postdocs. And we are looking for exceptional undergraduate RAs interested in learning about cognitive psychology/neuroscience. Please feel free to email me or visit our web site for further details.
