We study a wide range of questions in cognitive neuroscience including perception, attention, memory and motivation. Our research is conducted on both normal young adults, using volunteers from the campus student population, and on older adults.

A central focus of the research conducted in our Lab is the integration of different neuroimaging methods including fast optical (EROS), optical spectroscopy (NIRS), functional MRI (fMRI) and evoked potentials (ERPs).   By combining different methods we get a more complete picture of the physiological events that occur in the brain during information processing.  Optical methods, which record both neuronal signals (EROS) and slower signals related to hemodynamic activity (NIRS), play a pivotal role in this endeavor.  We have developed techniques for the alignment of measurements obtained with different techniques as well for the software integration of the different signals.
