Kristen Mackiewicz Seghete, Ph.D.

Portrait of Dr. Kristen Mackiewicz Seghete, principal investigator at the SCAN Lab

Dr. Mackiewicz Seghete earned her doctorate in clinical psychology from the University of Colorado Boulder, completing her clinical internship in the Department of Child Psychiatry at the University of Illinois Medical Center in Chicago. After graduation, she completed a two-year NIAAA postdoctoral fellowship in the Department of Behavioral Neuroscience at OHSU. She is currently an Assistant Professor in the Department of Psychiatry at OHSU. Her basic research interests are focused on executive function, cognitive and affective neurobiological markers of risk for psychopathology, and the effect of childhood maltreatment on cognitive and affective brain processes across the lifespan. Additionally, Dr. Mackiewicz Seghete is interested in directly bridging basic neuroimaging work with clinical research on preventative interventions. As such, one current project is focused on examining the neurobiological mechanisms of action of a preventative, perinatal mindfulness-based intervention (Mindfulness Based Cognitive Therapy) in women at heightened risk of postpartum depression. Dr. Mackiewicz Seghete's research is strongly influenced by her areas of clinical work and expertise, which include pediatric neuropsychology, interpersonal trauma, mindfulness-based interventions, and dyadic work.

Bonnie Nagel, Ph.D.

Dr. Bonnie Nagel

Dr. Nagel is Professor of Psychiatry and Behavioral Neuroscience at Oregon Health & Science University, where she serves as the Vice Chair for Research in the Departmentof Psychiatry, directs the Developmental Brain Imaging Laboratory, and is the Director of pediatric neuropsychology and a practicing neuropsychologist within the Division of Child and Adolescent Psychiatry. Dr. Nagel's research focuses on adolescent brain and cognitive development in healthy and at-risk populations. Her work has primarily focused on understanding the development of executive, emotional, and reward-based networks in the brain using neuroimagingand how perturbations to these systems may result in a heightened vulnerability for mental illness during the adolescent years. More specifically, her lab has been conducting longitudinal neuroimaging studies of Portland-area youth for more than a decade, with aims toward identifying neurobiological markers of risk and resilience for psychopathology, including addiction, and hopes of ultimately informing more targeted intervention and prevention efforts. She is a Principal Investigator on several federally-funded National multi-siteprojects toward that end, including the National Consortium on Alcohol & Neurodevelopment in Adolescence (NCANDA) and the Adolescent Brain Cognitive Development Study (ABCD).

Alice Graham, Ph.D.

Dr. Alice Graham

Dr. Graham is a developmental neuroscientist and clinical psychologist. She received her PhD in clinical psychology from the University of Oregon and completed her clinical internship in the Child Development & Rehabilitation Center in the Department of Psychiatry at OHSU. Dr. Graham is an Assistant Professor in the Departments of Psychiatry and Behavioral Neuroscience and a Principal Investigator in the Development Cognition and Neuroimaging (DCAN) Lab at OHSU. Dr. Graham studies the developing brain beginning soon after birth and is interested in how the early environment, beginning in the prenatal period, influences developing brain systems. Dr. Graham uses structural and functional MRI to characterize the developing brain in relation to environmental influences and patterns of behavioral development. Her work in the DCAN Lab also includes a focus on optimizing tools in order to better assess early brain development and how it differs between individuals. Dr. Graham's research also addresses how clinical intervention can be used to advance understanding of brain development and ameliorate effects of exposure to early life stress. The overarching goal of Dr. Graham's work is to prevent psychiatric disorders and support health brain development.

Gracie Arnone, BS


Gracie graduated one year early from the University of Oregon with a B.S. in Psychology and a focus in Neuropsychology. There she researched motivational and affective influences on eating behaviors and how the brain correlates behind those behaviors. Her primary research experience has involved preventative interventions, cognitive reappraisal, and neuroimaging. Her research interests include preventative science, maternal and natal well-being, early childhood intervention, and positive emotionality. Gracie is excited to help coordinate the Maternal Well-Being study and Roo Study as well as be involved in general lab management.

Kara Gallemore, BS


Kara recently graduated with a B.S. from the OHSU-PSU School of Public Health. At PSU, she was a part of Build EXITO, a program that specializes in training biomedical undergraduates with a focus on research. It is through Build EXITO that Kara came to join the SCAN Lab team. Kara's research interests include epidemiology with an emphasis on chronic disease prevention. In particular, she hopes to study the newly emerged and rapidly growing field of Developmental Origins of Health and Disease (DOHaD) at OHSU. At the SCAN Lab, Kara is spearheading a project that examines the incidence of neurodevelopmental disorders in adolescents with a history of maltreatment, as well as working on a study that is analyzing the effects of stress on correctional officers. 

Kathleen Dillon


Kathleen graduated from Loyola University Chicago with a B.S. in Psychology. While at Loyola, her honors thesis was concerned with the role of bilingualism on executive functioning in Latino, school-age children. Most recently, she graduated from Teachers College, Columbia University with an M.A. in Clinical Psychology. At Columbia, her concentration was Women, Gender, and Sexuality. Her thesis was related to the impact of division of household labor on relationship satisfaction, parenting stress, and cortisol levels in queer mothers. As of present, her research interests include maternal psychology, women’s studies and gender studies, and stress & resilience in gender and sexual minorities. Kathleen is thrilled to join the SCAN Lab and act as the Research Coordinator for a NIDA-funded research study with pregnant and postpartum women.

Olivia Doyle


I am a Research Assistant in DCAN Lab. I work primarily on the Autism study doing data management and performing neuropsychological testing. I also operating MRI scans for multiple studies; working with children with ASD, ADHD, and infants. My research interests include, executive functioning in typical and atypical children, DTI imaging and gender differences in ASD. I got my B.A. in Psychology with a minor in Neuroscience from Lewis and Clark College and I hope to pursue a PhD in Clinical Psychology. When I am not at work I am usually hanging out with my cat, bouldering or making pasta.

Michaela Cordova BA, CADC-I


Michaela is a Research Associate for the Developmental Cognition and Neuroimaging (DCAN) lab in the Department of Behavioral Neuroscience at OHSU, collaborating across multiple grants and projects through independent and collaborative investigation. Michaela joined DCAN in the fall of 2014 after previously working with dual-diagnosis clients as a Certified Alcohol and Drug Counselor (CADC-I). Her projects utilize behavioral and neuroimaging data, as well as machine learning methods, to explore atypical neurodevelopment across the lifespan, neurodevelopmental risk factors, and comorbidities effecting mood and cognition. In the SCAN lab, Michaela brings her clinical expertise conducting formal diagnostic interviews for the Maternal Well-Being study.
