Leopoldo J. Cabassa, Ph.D., M.S.W
Assistant Professor of Clinical Psychiatric Social Work (in Psychiatry), Department of Psychiatry, College of Physicians and Surgeons, Columbia University
Assistant Director, New York State Center of Excellence for Cultural Competence, New York State Psychiatric Institute

Dr. Cabassa received his M.S.W and Ph. D. from the George Warren Brown School of Social Work at Washington University in St. Louis.  Prior to joining the faculty at Columbia, Dr. Cabassa was an Assistant Professor at the University of Southern California (USC) School of Social Work and at the USC Keck School of Medicine Department of Psychiatry and Behavioral Sciences.  His research focuses on understanding the causes of racial and ethnic disparities in health and mental health care and in developing and implementing culturally tailored interventions aimed at reducing these inequities in care.  He was recently awarded an NIMH Mentored Research Scientist Development Award (K01) to examine the implementation of health care interventions for Hispanics with serious mental illness.  In this project, he is developing a collaborative planning approach for intervention research that blends principles of community-based participatory research and intervention mapping to modify and assess the feasibility an acceptability of an existing care manger intervention for outpatient public mental health clinics. Dr. Cabassa’s long-term career goal is to establish an independent program of research focused on the implementation of integrated physical and mental health services in the public mental health system to improve the physical health of underserved racial and ethnic minorities with serious mental illness.

Dr. Joan Cook, Ph.D., is on faculty at the Yale School of Medicine, Department of Psychiatry and is a researcher at the National Center for PTSD. She has numerous publications in the traumatic stress and geriatric mental health fields, including scientific papers on the phenomenology, assessment and treatment of older adult trauma survivors. Dr. Cook has worked clinically with a range of trauma survivors, including combat veterans and former prisoners of war, men and women who have been physically and sexually assaulted in childhood and adulthood, and survivors of the World Trade Center bombing. She is funded by the National Institute of Mental Health to study the dissemination and implementation of effective mental health services in the community.

Wendi Cross, Ph.D. Associate Professor of Psychiatry (Psychology), University of Rochester Medical Center, Rochester, NY.
Wendi Cross has a Ph.D. in Clinical Psychology from Ohio University and is currently an Associate Professor in the Department of Psychiatry at the University of Rochester Medical Center.  Her NIMH-funded career development award focuses on developing and testing models, methods and measures for training individuals charged with carrying forth a variety of evidence-based preventive interventions into community settings.  Her research crosscuts interventions and practices, and she is collaborating with investigators on a variety of studies with an emphasis on using observational measures of  implementer fidelity.  She has studied train-the-trainer models, community-based suicide prevention training programs, and implementation fidelity in a school-based preventive intervention.  She plans to use the IRI training opportunity to develop a broader perspective on implementation science and to use her new knowledge and skills to conduct research that will create evidence-based practices for cost effective implementer training and high quality intervention delivery.

Shannon Dorsey, Ph.D., is Associate Professor in the Department of Psychology at the University of Washington. Her research is on evidence-based treatments (EBT) for children and adolescents, with a particular focus on dissemination and implementation of EBT domestically and internationally.  Her work has often focused on Trauma-focused Cognitive Behavioral Therapy (TF-CBT), with hybrid research designs that include both effectiveness and implementation questions. Research has focused on adaptation for unique populations (e.g., foster care) and on training and supervision strategies to deliver TF-CBT and other EBT.  Dr. Dorsey is a Principal Investigator on two NIH-funded randomized controlled trials (RCT) involving TF-CBT, both of which include implementation and clinical outcome research questions. The first, in Washington State, studies the role of supervisors in public mental health settings in supporting EBP with clinicians under their supervision. It includes both a descriptive study of common supervision practices and a RCT of supervision strategies. The second, in Tanzania and Kenya, is a RCT of TF-CBT using a task-shifting/task-sharing model in which lay counselors, with little to no prior mental health training, deliver group-based TF-CBT to children and adolescents who have experienced the death of one or both parents, under close supervision by TF-CBT experts. Dr. Dorsey is also involved in common elements/modular EBT training initiatives and research both in Washington State and internationally, in low and middle income countries. With colleagues at Johns Hopkins Bloomberg School of Public Health, she also is involved in RCT and feasibility studies in Southern Iraq, the Thailand-Burma border, Colombia, Zambia, and Ethiopia.  

Seth Himelhoch, M.D., M.P.H., is a psychiatrist and Associate Professor at the University of Maryland School of Medicine in the Department of Psychiatry. He currently serves as the Director of Mental Health and Substance Abuse Services at the University of Maryland School of Medicine’s infectious diseases clinic, is the Director of Research in the Division of Residency Training, and the Acting Core Clinical Director for the VISN 5 MIRECC. He is board certified in general psychiatry and psychosomatic medicine and is a Fellow of the American Psychiatric Association. Dr. Himelhoch received his medical degree from the University of Michigan School of Medicine and completed his residency training in general psychiatry at the University of California, San Francisco. From 2001-2003 he was a Fellow in the Robert Wood Johnson Clinical Scholars Program at Johns Hopkins School of Medicine where he concurrently received a Masters Degree in Public Health. Dr. Himelhoch’s clinical and research experiences have focused on access to care and treatment of co-occurring psychiatric and drug use disorders among individuals with HIV. More recently, he has used telecommunication technology to overcome barriers to care for the treatment of depression and PTSD. He is actively involved in the clinical and research supervision of both psychiatry residents, fellows and psychology interns.

Patricia Kohl, Ph.D., is an assistant professor at the George Warren Brown School of Social Work at Washington University. Her research, which focuses on the implementation of empirically supported behavioral parent training interventions within non-traditional service settings, is informed by nearly a decade of clinical experience with maltreated children and their families. Her current line of inquiry is informed by research she has conducted or is currently conducting in the following areas: (1) characteristics which influence parenting behaviors and child outcomes among families in the child welfare service sector, (2) organizational context of agencies providing parent training, and (3) the effectiveness of Pathways Triple P (PTP), one behavioral parent training intervention, when delivered to families with open child welfare cases.  Dr. Kohl is currently carrying out a randomized control trial to determine if PTP results in better behavioral and safety outcomes than treatment as usual (TAU) for African American and European American children in the child welfare system and to evaluate how the cost-effectiveness of PTP compares to TAU. She is also currently working to adapt an evidence-base parent training program to increase father participation, as well as to improve father-child interactions. Additionally, her work includes analyzing data from the National Survey of Child and Adolescent Well-being, a landmark study of children and families who have been investigated for child maltreatment. Dr. Kohl’s work has received financial support from the National Institute of Child Health and Human Development, National Institute of Mental Health and the Centers for Disease Control and Prevention. She received her PhD from the University of North Carolina at Chapel Hill in 2006, after which she joined the faculty of the Brown School. She teaches Social Work Practice in Early Childhood and Social Work Practice with Children in Families.

Brent Mausbach, Ph.D. Dr. Mausbach obtained his bachelor’s degree from Concordia College in Moorhead, MN and his PhD in Clinical Psychology from the Pacific Graduate School of Psychology in Palo Alto, CA. He completed his clinical psychology internship at the VA Black Hills Healthcare System, after which he received post-doctoral training at both Stanford University and UCSD with a specialization in Geropsychiatry. Dr. Mausbach has been a faculty member at UCSD since July, 2007. Dr. Mausbach's research focuses on bridging basic scientific research with clinical services in two domains. The first examines the links between stress/coping and health outcomes, with an emphasis on positive psychological states (e.g., mastery, self-efficacy) and their association with health outcomes and well-being. This research has led Dr. Mausbach to test psychosocial interventions designed to improve emotional and physical well-being in chronically stressed populations (e.g., Alzheimer’s caregivers).  Dr. Mausbach’s second research domain is the assessment and treatment of middle-aged and older adults with schizophrenia. He has sought novel methods of assessing functional capacity in this population, with coinciding development of treatments to improve functioning. Dr. Mausbach is a licensed clinical psychologist specializing in behavioral treatments for a) caregiver stress and b) improving functioning in patients with schizophrenia.

Alan McGuire, Ph.D., M.S., is a Core Investigator at the Center for Implementing Evidence-Based Practices at the Indianapolis VA Medical Center. In addition, he is an Assistant Scientist at the Indiana University Purdue University Indianapolis (IUPUI) Department of Psychology and Clinical Research Scientist for the ACT Center of Indiana—a statewide training and technical assistance center. He received his Bachelor of Arts in psychology from Ohio Wesleyan University in 2002 and his Master of Science in 2005 and Ph.D. in 2008, both from IUPUI.
Alan conducts research on mental health services for people with severe mental illness, provides training and consultation to mental health centers, as well as providing direct mental health services. His research interests include treatment goal setting and illness self-management, particularly in schizophrenia.

Lisa Saldana, Ph.D., has a doctorate in clinical psychology with a research and clinical emphasis in child maltreatment and evidence-based practice. She is working on the development of preventive interventions to address the needs of families involved in the child welfare system, with cases complicated by substance abuse. She currently is the PI on a NIDA funded Career Development award to develop an integrative treatment for maternal substance abuse and child neglect, and is a co-investigator on an implementation trial examining two implementation strategies to scale-up MTFC, an evidence-based practice for youth in foster care. In addition, she is working on research grants focusing on the economic evaluation of MTFC, and on dissemination efforts of a more recent evidence-based practice for supporting foster parents.
As a participant in the IRI, Dr. Saldana will focus her efforts on developing a strategy to assess and evaluate costs of the stages of implementation for evidence-based practices.

Alex Sox-Harris, Ph.D., M.S., Research Coordinator, Veterans Affairs (VA) Substance Use Disorder Quality Enhancement Research Initiative (QUERI); Associate Director, VA Program Evaluation and Resource Center; Research Health Scientist, Center for Health Care Evaluation, VA Palo Alto

Alex Sox-Harris has a Ph.D in Counseling Psychology and M.S in Statistics from Stanford University. He is Associate Director of VA Program Evaluation and Resource Center, tasked with monitoring the treatment of VA patients with Substance Use Disorders (SUD). He is also the Research Coordinator of the VA SUD QUERI, striving to improve the quality of care for patients with SUD through implementation research. His primary research program has focused on validating measures of SUD treatment quality and refining the processes by which quality measures are developed. He has also documented great variation in the application of consensus standards of SUD care within the VA system. He hopes to use his participation in IRI to develop implementation studies aimed at reducing this undesirable variation and, more broadly, to increase the SUD QUERI’s contribution to implementation science.
