  • Developmental Cognitive Neuroscience

  • Attention

Biography:

Brandon Keehn received his Ph.D. from the San Diego State University / University of California, San Diego Joint Doctoral Program in Language and Communicative Disorders in 2011.  He completed a postdoctoral fellowship at Boston Children’s Hospital and Harvard Medical School.  In fall 2014 he joined Purdue University with a joint appointment in the Departments of Speech, Language, and Hearing Sciences and Psychological Sciences. 

Dr. Keehn’s research uses a multimodal (fMRI, EEG, eye-tracking) approach to understanding attentional strengths and weaknesses and their neurofunctional underpinnings in individuals at-risk for or diagnosed with autism spectrum disorder (ASD).  The aim of this research is to provide insight into how early impairments in attention impact the development of social and communicative abilities in children with ASD.  Ultimately, the goal of this research is to identify behavioral and biological markers to assist in making an earlier diagnosis of ASD and to determine potential targets for early intervention.
