Meet Our Team!


So Hyun "Sophy" Kim, Ph.D.

Lab Director

Dr. So Hyun “Sophy” Kim, is an Associate Professor at the School of Psychology at Korea Univesity. Dr. Kim is a clinical researcher with an extensive background in identification of early behavioral phenotypes and examining developmental trajectories of children with ASD and other NDDs.  She has developed a new language assessment tool, the Observation of Spontaneous Expressive Language (OSEL), which is now undergoing a national norm based on a partnership with the publisher, WPS, in collaboration with Dr. Catherine Lord. She has also led the development of the new treatment outcome measure for ASD, the Brief Observation of Social Communication Change (BOSCC) with Dr. Catherine Lord. Currently, she is a PI of a NIMH funded project designed to examine the mechanisms of early, parent-mediated interventions for toddlers with ASD (1R01MH114925-01). Most recently, Dr. Kim has led efforts to examine school readiness in kindergarteners with ASD while integrating behavioral and electrophysiological (ERP/EEG) methods, with a particular focus on executive function.



Dr. Elizabeth McKernan is a first-year postdoctoral fellow in the ASD & Developmental Science Lab at the Center for Autism and the Developing Brain (CADB). She completed her doctorate in school psychology at Syracuse University, and her predoctoral clinical internship at the Penn Center for Mental Health at the University of Pennsylvania Perelman School of Medicine. Dr. McKernan has extensive experience in the assessment and diagnosis of autism spectrum disorder (ASD). She is interested in the heterogeneity of ASD, the presentation of internalizing symptoms such as anxiety and depression in individuals with ASD, and how we measure these constructs. In her current role, Dr. McKernan is involved in research examining early behavioral features and trajectories of children with ASD, as well as neural correlates of executive function and school readiness in children with ASD.

Post-Doctoral Fellow

Brittany Manning, Ph.D., CCC-SLP

Dr. Brittany Manning is a postdoctoral fellow in the ASD and Developmental Science Lab. Brittany received her B.S. and M.S. in Communication Sciences and Disorders at the University of Wisconsin-Madison and worked as a speech-language pathologist before returning to complete her Ph.D. at Northwestern University. Brittany’s research focuses on better understanding language and brain development in children with autism and developmental language disorder. In particular, Brittany is interested in the relation between parent-child interaction and early language development and the co-occurrence of language, social, and mental health challenges. Brittany is also passionate about improving methods for studying child development and, during her PhD studies, helped to develop a naturalistic EEG paradigm to investigate toddler-parent social engagement and a telepractice method for conducting child language sampling. Currently, Brittany is involved in research investigating the relation between EEG/ERP markers and later language outcomes as well as a parent-mediated intervention aimed at increasing language and play skills in toddlers with autism.


 Alyssa Viggiano graduated from Syracuse University in 2020 with a B.S in Psychology and Neuroscience and a minor in Disability Studies. At Syracuse, Alyssa worked in the Mind and Body lab, studying the cognitive and psychophysiological benefits of mindfulness practices with children. She also worked in the Neuroimmunology Lab for the NYS Department of Health at the Wadsworth Center, studying the mechanisms by which the immune and nervous systems regulate each other, and whether or not this impacts the incidence of neuroimmune disorders such as ASD. Most recently, Alyssa was a research assistant in the Center for Autism Research and Electrophysiology (CARE) Lab at Syracuse University. The CARE Lab studies the ways in which children on the autism spectrum process and integrate sensory information. Alyssa also completed independent research for her thesis in the Reneè Crown Honors Program at Syracuse. Her thesis studied the relationship between autism, ADHD traits, and sensory features and whether or not these differed between genders. Alyssa plans to pursue a Ph.D in clinical psychology and continue to research gender differences in autism, finding better diagnostic and intervention techniques for girls on the autism spectrum.
