Educational Background

  • Postdoctoral Fellow, Yale University, 1993-1995
  • Ph.D., Boston University, 1994

Research Interests

My research is in the area of developmental neuropsychology and developmental cognitive neuroscience. My work examines the behaviors that are associated with neurodevelopmental and neuropsychiatric disorders like autism spectrum disorders, Tourette syndrome, obsessive-compulsive disorder and other disorders characterized by repetitive behavior and restricted interests.

My work uses a variety of methods to ask questions about both typical and atypical development. For example, my work has examined brain structure and function (using EEG and MRI) as it relates to behavior in children with rare and common genetic variants, as well as in typically developing children and adolescents. I collaborate with several members of Geisinger Health System including neuroradiologists, neurodevelopmental pediatricians, and geneticists. My research group includes a talented team of Bucknell undergraduate and graduate students.

Undergraduate or graduate students or research assistants who are looking for research opportunities and who have interests or experiences in neuroscience, genetics, computer programming and computational sciences, psychophysiology and neuroimaging, especially as they relate to neurodevelopmental disorders, should contact me at
