As a developmental clinical neuropsychologist, my clinical research interests examine the neurophysiological mechanisms underlying the cognitive and social-emotional abilities of individuals with neurological conditions across the lifespan. My research has a specific emphasis on examining the biopsychosocial factors that contribute to optimal executive and emotional functioning following neurological injury during childhood. Executive and emotional functions are of interest to me because of the importance of these skills in daily life. I have observed the significant disruption in the development of these skills in children and devastating loss of these skills in adults following frontal-subcortical system lesions, including disruption of white matter pathways. My focus on adaptive functioning capabilities grew out of my postdoctoral training with adults with vascular dementia, and subsequently my clinical research with adult survivors of childhood brain tumors. Both sets of patients and their families reported significant concern about independent living skills that often superseded cognitive concerns. My interest in these brain-behavior relationships is broad, spanning a wide range of research methods, psychological domains, and populations. Three primary foci of my research program are studies of survivors of childhood brain tumors, neuroimaging studies of executive functions, and psychophysiological and neuroimaging studies of emotion.
The major focus of my lab is examining the adaptive functioning of adult survivors of childhood brain tumors. We are evaluating a group of young adults who are in their twenties and who were followed longitudinally as children beginning at the time of diagnosis and treatment. The goal is to identify the childhood and current adult predictors of adaptive functioning. In particular, we are interested in identifying executive and emotional functioning correlates as well as neuroimaging correlates of adult survivors’ adaptive living skills. The American Cancer Society (ACS) has awarded me a Research Scholar Grant for this program of research. http://www.whsc.emory.edu/press_releases2.cfm?announcement_id_seq=11303
Building on the neuroimaging paradigms (functional MRI, diffusion tensor imaging, default mode network) used in the ACS study, I have a specific focus of research on executive functions in other clinical populations. Two extensions of this neuroimaging work are pilot collaborations funded by Children’s Health Care of Atlanta: 1) to examine long-term outcomes following infant heart surgery (with Bill Mahle) and 2) recovery in high school football concussion (with Tom Burns). In collaboration with John Schoffner, Robin Morris and Diana Robins, we are examining the neural mechanisms of mitochondrial dysfunction in individuals with and without autism spectrum disorder (ASD; funded by Department of Defense and Foundation of Mitochondrial Medicine). FMRI research projects that examine neural activation during a false memory paradigm (with Heather Kleider funded by the Joint Center for Advanced Brain Imaging seed grant) and executive functioning/ cognitive control paradigms (with David Washburn funded by NICHD) are underway.
Most recently, our lab was awarded funding from the National Institute of Disability and Rehabilitation Research (with Julie Haarbauer-Krupa), based on the GSU Language and Literacy Pilot Study, to longitudinally examine the role of executive function in language and reading outcomes in school age children following traumatic brain injury before the age of five years.
Another area of research builds upon my interest in emotion using a multilevel approach including psychophysiological methods (i.e., facial electromyography, skin conductance, and heart rate) and neuroimaging markers. One area of focus is on emotion perception in ASD and typically developing individuals. We have found disrupted facial mimicry in ASD as measured by facial EMG (Mumaw, King, & Robins, 2007 IMFAR; Rozga, Mumaw, King, & Robins, INSAR 2009) using dynamic audiovisual emotion perception task (funded by Autism Speaks and GSU Brains and Behavior Seed Grant; co-PI Diana Robins). In addition, neuroimaging data (fMRI, DTI) was obtained to examine correlates with empathy (seed grant provided by NSF-funded Center for Behavioral Neuroscience). I also serve as a co-mentor for Negar Fani who was awarded an NIMH F32 postdoctoral fellowship to examine the neuroendophenotypes of PTSD.
