Meet Our Team

To accomplish our goals, we have formed teams of clinical investigators and basic behavioral investigators for our research projects.


The Center is led by Keith H. Nuechterlein, Ph.D., Professor of Psychology at the University of California, Los Angeles, and Director of the Aftercare Program, a research clinic for schizophrenic patients, UCLA Semel Institute of Neuroscience and Human Behavior. Dr. Nuechterlein specializes in neurocognitive processes in schizophrenia, especially as they relate to both the developmental course of the disorder and to functional outcome. Dr. Nuechterlein’s ongoing longitudinal study of the early course of schizophrenia, “Developmental Processes in Schizophrenic Disorders”, has closely examined the influence of specific neurocognitive vulnerability indicators on the early course of first-episode patients, with an emphasis on occupational and educational outcome. He holds a joint... more

Dr. Bearden is Associate Professor in Residence of Psychiatry and Biobehavioral Sciences and Psychology and the Assessment Director of the CAPPS research program. She earned her doctoral degree in Clinical Psychology from the University of Pennsylvania in 1999. After completing a clinical internship at UC San Diego/VA Medical Center, she completed postdoctoral training in Pedatric Cognitive Neuroscience at the Penn/Children’s Hospital of Philadelphia, before joining the UCLA faculty in 2003, where she was recently promoted to Associate Professor. Her research aims to understand genetic influences on brain structure in the development of psychosis, using converging methods to study cognition and neuroanatomy in clinical high-risk samples (adolescents at ultra high-risk for psychosis),... more

Thomas R. Belin, Ph.D., is a Professor in the UCLA Department of Biostatistics who since 1995 has had a joint appointment in the UCLA Department of Psychiatry and Biobehavioral Sciences.

Gerhard Hellemann, Ph.D., Assistant Professor, received his doctorate in psychology from UCLA where he studied psychometrics under Dr. Peter Bentler. Dr. Hellemann has both theoretical and practical experience with mixed models, hierarchical data, structural equation modeling, factor analysis, and path modeling techniques, all of which are essential for this center’s research. He has worked closely with many of the project scientists both during his graduate studies and more recently as a SIStat consultant. He has played a key role in the center’s initial cross-project analyses.

Gerhard Hellemann, Ph.D., biostatistician, received a Dipl.Stat. From the University of Dortmund and a Ph.D. in Psychometrics and Measurement from UCLA in 2005.

Dr. Hellemann’s main research... more

He received his Ph.D. from the UCLA Department of Psychology in 1990. His areas of special research interest include: 1) the prediction of psychotic symptom return in individuals in the early phase of schizophrenia; 2) the examination of psychological factors affecting medication adherence, such as insight and attitudes toward antipsychotic medication; and 3) the impact of long-acting antipsychotic medication on clinical outcome in first-episode schizophrenia.

Joseph Ventura, Ph.D., is a Senior Research Psychologist and member of the Faculty in the UCLA, Department of Psychiatry & Biobehavioral Sciences.
