Katherine Gotham, PhD

Assistant Professor, Rowan University

(She/her/hers)

Dr. Katherine Gotham is an Assistant Professor in the Department of Psychology at Rowan University and Director of the Social, Emotional, and Affective Health (SEAHL) Lab. Dr. Gotham investigates emotion processing and emotional health problems in the context of the autism spectrum, using behavioral and psychophysiological methods. The SEAHL Lab aims to use that knowledge to develop more effective treatments to support emotional health in neurodivergent adolescents and adults. Dr. Gotham works closely with the TREND Lab to understand social and identity factors in the pathway to depression in autistic adults. Learn more about Dr. Gotham and her lab.

Autumn Kujawa, PhD

Associate Professor, Vanderbilt University

(She/her/hers)

Dr. Autumn Kujawa is an Associate Professor in Psychology and Human Development at Vanderbilt University and Director of the Mood, Emotion, and Development (MED) Lab. Dr. Kujawa's research aims to reduce the burden of mood disorders on youth and families. In particular, she examines how children and adolescents process and respond to emotion, the ways in which alterations in emotional processing contribute to the development of mood disorders, and how this knowledge can be translated to improve interventions. Her work focuses on a range of emotions, including reward responsiveness, threat reactivity and regulation, and sensitivity to social feedback, and takes a multimethod approach incorporating physiological, brain circuit, and behavioral measures. With the TREND Lab, Dr. Kujawa examines EEG methodologies with autistic youth and potential neural indices of reward responsivity and associations with depression.

Zachary J. Williams, BS

MD/PhD Candidate, Vanderbilt University School of Medicine

(He/him/his)

Zachary “Zack” Williams is a MD/PhD candidate with autism in the Neuroscience Graduate Program and Department of Hearing and Speech Sciences at Vanderbilt University. He is also an affiliate of the Vanderbilt University Frist Center for Autism and Innovation, co-chair of the Autism Intervention Research Network on Physical Health (AIR-P) Autistic Researchers Review Board, co-chair of the INSAR Autistic Researchers Committee, as well as the co-founder of Autism PROMnet. He received his BS in psychology from Yale University in 2017, where he was heavily involved in autism research at the Yale Child Study Center. Zack's current research focuses on the sensory manifestations of autism in adulthood, the assessment and treatment of co-occurring physical and mental health problems in autistic adults, and the development of novel questionnaires and clinical measures to assess core and associated features of autism across the lifespan. He works closely with the TREND Lab to investigate social risk and protective factors for depression in autistic youth and potential intervention approaches.
