Blue Brain pattern for the BRAVE Research Center (formerly known as BRAVE Youth Lab)



Ryan Herringa

Credentials: MD, PhD

Position title: Associate Professor, Child & Adolescent Psychiatry


Dr. Herringa is the UW Health Professor in Child and Adolescent Psychiatry, Director of the Division of Child and Adolescent Psychiatry, and Director of the BRAVE Research Collaborative. As a pediatric psychiatrist, he is an expert in the treatment of traumatized youth and families using psychotherapy and pharmacological approaches. As a neuroscientist, his work aims to better understand the effects of trauma on the developing brain as well as the body. Dr. Herringa earned his M.D. and Ph.D. as part of the Medical Scientist Training Program at the University of Wisconsin. He completed his Ph.D. in Neuroscience under the direction of Dr. Ned Kalin, during which time he studied the effects of stress on gene regulation in the amygdala, the brain’s fear center. He then completed a clinical-research residency in general psychiatry and pediatric psychiatry at the University of Pittsburgh, one of the nation’s premier psychiatry residency programs. Following this, he returned to the University of Wisconsin as faculty, where his research collaborative has been conducting seminal studies on brain development in trauma-exposed youth and youth with PTSD. Dr. Herringa has received funding from many agencies to conduct this work, including the National Institute of Mental Health, the Brain and Behavior Research Foundation, the American Academy of Child and Adolescent Psychiatry, and the UW Institute for Clinical and Translational Research.

Research Scientists

Sara Heyn

Credentials: BS, JD, PhD

Sara is a clinical and developmental neuroscientist and lawyer who is passionate about understanding brain-body mechanisms underlying links between early life trauma, structural and functional brain development, and internalizing and externalizing behaviors. She is particularly interested in the relationship between trauma and delinquent behavior that leads to involvement in the juvenile criminal justice system, as well as the development of trauma-informed treatment interventions. Sara earned her bachelor’s degree in psychology from Colorado State University in 2014 studying jury decision-making processes under Dr. Matthew Rhodes. Next, she graduated from the Neuroscience and Public Policy Program at the University of Wisconsin-Madison, where she earned a JD from the UW Law School in 2016, followed by a PhD in Neuroscience under the mentorship of Dr. Ryan Herringa. Sara currently works as a research scientist in the Department of Psychiatry where she utilizes structural and functional neuroimaging and in-depth clinical and trauma assessment tools to identify biomarkers of trauma sequalae and is in the development and implementation of mindfulness-based interventions in youth and families, virtual-reality biofeedback for emotion regulation skills, and neuroplastinogen-assisted psychotherapy in youth with PTSD.

Justin Russell

Credentials: BA, PhD

Position title: Research Scientist

Justin’s research is driven by his desire to improve our collective understanding how early life adversity may moderate social and emotional development, and foment the onset of severe psychological problems. Justin earned his bachelor’s degree in psychology from the University of Rochester in 2010, where he conducted research into the impact of family adversity on socioemotional growth under the mentorship of Drs. Patrick Davies and Melissa Sturge-Apple. Before beginning graduate study, Justin held several positions at the Mt. Hope Family Center, working with maltreated children in both research and clinical settings. Justin completed his Ph.D. in psychology at Iowa State University in 2018, under the direction of Drs. Carl Weems and Monica Marsee. During that time, Justin began to investigate the neurological sequelae of childhood traumatic stress, the nature of post-trauma symptoms, and the course of children’s brain development. His dissertation utilized data from a large, nationally representative sample of typically developing youth to identify normative growth changes in the amygdala, an area with enormous relevance for psychopathology. Justin is currently a post-doctoral trainee in the NRSA T32 Training Program in Emotion Research.

Taylor Keding

Credentials: BS, PhD

Position title: Research Scientist

Taylor is a developmental and clinical research scientist, working jointly with the University of Wisconsin School of Medicine & Public Health and Yale University. His research broadly focuses on characterizing the development of the brain’s emotion circuitry during childhood and adolescence. More specifically, he is interested in the relationship between early-life adversity and the timing (initiation and pace) of circuit neurodevelopment, and how atypical maturation is related to pediatric psychopathology. He received his Ph.D. in Neuroscience (2021) from the University of Wisconsin-Madison under the mentorship of Dr. Ryan Herringa, where he studied the development of amygdala-prefrontal cortex connectivity after exposure to early-life violence and predictive markers of pediatric depression, anxiety, and post-traumatic stress disorder. He then completed a postdoctoral fellowship (2023) at Yale’s Child Study Center under the mentorship of Dr. Dylan Gee, where he applied patterns of frontolimbic circuit maturation to questions of familial risk for psychopathology and treatment-related symptom changes. His work makes extensive use of neuroimaging (structural and functional MRI, DTI), clinical/behavioral assessments, and computational and machine learning approaches to study individual differences in neurodevelopment.

Postdoctoral Fellows

Matthew Peverill

Credentials: BA, MS, PhD

Position title: Postdoctoral Fellow

Matt earned his PhD in clinical psychology from the University of Washington in 2021 under the mentorship of Dr. Katie McLaughlin. He is most interested in research with the potential to realize improved clinical outcomes in vulnerable, under-served, and under-studied children and families. To that end, his research has employed neuropsychological, psychological, and epidemiological tools to explore multiple mechanisms of mental health risk in children exposed to adverse experiences including child maltreatment, neglect, and poverty. His dissertation used multimodal measurement of socioeconomic status to research the effects of poverty on psychopathology risk factors including stress, emotion regulation, and social cognition. More information on Matt can be found on his website.
