Current Graduate Students
Kathleen is a sixth year graduate student working towards her Ph.D. in the Neuroscience and Behavior program at UNL. She is broadly interested in the use of advanced statistical techniques in examining predictive pathways to developmental behavior disorders. Kathleen has specific interests in the effects of chronic stress on developmental neurobiology and functional brain development. She is currently working on a dissertation project investigating the neurophysiological correlates of emotion regulation in maltreated children using event-related potentials (ERP).

Allison is a second year graduate student in Psychology with a focus Social Cognitive Neuroscience. Her research involves the use of neuroimaging technology to develop a more comprehensive understanding of social perceptions and intergroup relations. She has a number of current projects centered on perceptions and categorizations of race, stereotypes, and the impacts of observing outgroup prejudice.

Cathryn Cortesa is a first year graduate student working toward her Ph.D. in Developmental Psychology. She is broadly interested in research with an ecological approach to early childhood development. This year, Cathryn will be working with the Developmental Brain Lab, and hopes to use brain-imaging techniques in research to better understand and better predict risk for future self-regulatory, attentional, and learning difficulties, especially in high-risk populations
Patrick Ledwidge, B.A.
Patrick Ledwidge is a first year Ph.D. student in the Neuroscience and Behavior program at UNL with a particular interest in Developmental Cognitive Neuroscience. His research interests involve using neuroimaging techniques to study the changes in cognition between different typically and atypically developing populations. He has a specific interest in investigating the long-term effects of traumatic brain injury on cognitive development and maintenance.
Before coming to UNL and the dBrain lab, Patrick received his B.A. in Psychology from DePauw University where he studied Psychology and Spanish. At DePauw, he was the research project coordinator in Dr. Terri Bonebright’s Perception Lab, where he conducted ERP research investigating contextual-dependent perceptions of interfering auditory and visual stimuli. He also has conducted research on auditory-emotion perception, sportsmanship, and emotion regulation.

Past Graduate Students
Caitlin Hudac, Ph.D.
My research interests apply the use of neuroimaging techniques (including EEG/ERP, MRI, NIRS, and MEG) to study the development of language, learning, and social development. The research that I conduct with the dBrain Lab is largely interdisciplinary, encompassing topics such as theory of mind development in infancy, emotion regulation and autonomic arousal, effects of sleep disruption on cognition, the involvement of reward circuitry when viewing art (neuroaesthetics), and brain plasticity following traumatic brain injury.Prior to coming to UNL, I was the research coordinator for Dr. Kevin Pelphrey at the Yale Child Study Center where I conducted pediatric autism research. We used fMRI to measure the social brain in children with autism, siblings unaffected by autism symptoms, and neurotypical children as young as 4 years of age. I also was involved in executing infant neuroimaging using fMRI.Currently, my research focuses on cognitive neural mechanisms across early development. More specifically, I study the early emergence of social cognition in infancy, such as mental state representations. I am interested in developing computational models to explore how these mechansism emerge in infants. I hope to apply my work to both typical and atypical development (e.g. autism, learning disorders).
