NCHAV Research
Overview
The National Center for Homelessness Among Veterans’ (NCHAV) own researchers, often times in collaboration with affiliated researchers and clinicians, study a varying array of critical topics in homelessness among Veterans. We produce public deliverables in the form of briefs, publications, and reports.
If you are interested in working with our research team, there are opportunities to become a Research Fellow or help to influence the research process by joining the Homeless Veterans Research Engagement Panel. Additionally, every Spring, NCHAV typically issues a request for proposals to conduct intramural and collaborative operations-based research project.
Deliverables
Briefs
Briefs are short summaries of a research study that are typically written to share important findings of the study, and implications of working with homeless Veteran populations, with VA Staff and providers to quickly read and understand.
Publications
Publications are articles or academic works that discuss research findings related to homeless Veteran populations. These works are made publicly available, allowing broader access for both academic audiences and the general public. Publications are typically longer and more detailed than research briefs.
Reports
Reports are technical summaries that describe findings of a research investigation or study, which describe the process, methodology, results and conclusions. They are usually intended for subject matter experts, researchers, or stakeholders.

Who We Are

Jack Tsai, PhD
Director of Research
Dr. Jack Tsai serves as Research Director of NCHAV, where he leads both administrative and research activities for the Homeless Program Office. Dr. Tsai is a licensed clinical psychologist with a PhD from Purdue University and an additional MS in Clinical Psychopharmacology. Prior to joining NCHAV, he served in numerous VA roles including as a front-line clinical provider for many years and in VISN leadership. He currently has a faculty appointment at the University of Texas, and previously served on the faculty at Yale University School of Medicine for a decade where he directed the Division of Mental Health Services Research. His dedication to improving the housing, health, and well-being of Veterans is evident through his ongoing work to advance care for Veterans and their families experiencing homelessness.
Dr. Hind A. Baydoun is a Research Health Science Specialist at NCHAV. She earned her PhD in Epidemiology from the University of Iowa, as well as an MPH in Epidemiology and Biostatistics, a BS in Nutrition and Dietetics, and a BS in Biology from the American University of Beirut. At NCHAV, her work primarily involves utilizing advanced statistical methods to support projects that target chronic disease prevention, addressing housing instability, homelessness, and justice-involved Veterans. With over 20 years of experience in academic, healthcare, and federal government environments, Dr. Baydoun has previously held positions as a Statistician with the Defense Health Agency at the Alexander T. Augusta Military Medical Center, an Epidemiologist with the U.S. Food and Drug Administration, and an Assistant Professor of Epidemiology in the Graduate Program in Public Health at Eastern Virginia Medical School. She has authored more than 250 peer-reviewed publications and presented over 90 abstracts in the areas of reproductive, chronic disease, and social epidemiology.
Dr. Rebecca Kinney is a Health Services Researcher with a focus on healthcare access and utilization among underserved veterans. Dr. Kinney received her Master of Public Health (MPH) at the University of Massachusetts Amherst and completed her PhD in Population Sciences and Health Outcomes Research at the University of Massachusetts Chan Medical School. She specializes in a mixed methods approach employing both quantitative and qualitative methods to her program evaluation, implementation science, and research efforts. Dr. Kinney’s most recent studies involved equity in diabetes care delivery and clinical practice, unsheltered homelessness, trauma informed care, food insecurity/quality, and patient engagement. Over the past year, Rebecca has worked closely with Dr. Tsai to explore how to better engage the most destitute unsheltered Veterans and better transition these individuals to sustainable, permanent housing. Additionally, given her interest in health care equity and access to care, she has worked closely with Dr. Casey and his team over the past few years to examine the impact of a trauma informed care approach in delivering Veteran care. Rebecca’s professional interests include health care access (e.g.., remote care), equity, and continuity of care among underserved populations.
Dr. Amanda Edwards Stewart is a clinical psychologist and researcher at NCHAV. She earned her PhD and MA in Clinical Psychology from Seattle Pacific University, and her MS and BS in Psychology from Evangel University. As a Clinical Investigator at NCHAV, Dr. Stewart focuses on assessing clinical interventions aimed at enhancing the lives and mental health of Veterans who are currently or have previously experienced homelessness. Before joining VA, Dr. Stewart worked as a subject matter expert in developing and evaluating technology solutions and spent twelve years as a clinical psychologist and researcher with active-duty military personnel.
Dr. Dorota Szymkowiak is a Health Science Specialist at NCHAV focusing on Veterans experiencing homelessness and housing instability. She completed a PhD in Medical Sociology at Rutgers University in New Jersey. Dr. Szymkowiak specializes in quantitative analyses of administrative data, including the electronic medical record as well as the Homeless Operations Management and Evaluation System (HOMES) and the Homeless Management Information System (HMIS). Dr. Szymkowiak’s current studies seek to delineate long-term outcomes for homeless Veterans within VHA, understand how best to engage Veterans at ongoing surge events, and to describe the extent of Veterans’ utilization of non-VA medical care in the community. She has been with NCHAV for 10 years and previously worked with a variety of data in public health settings. Dr. Szymkowiak’s professional interests include optimizing VHA healthcare and homeless programs performance to ultimately optimize outcomes for Veterans experiencing homelessness and housing instability.

The Homeless Veterans Research Engagement Panel (HV-REP)
The Homeless Veterans Research Engagement Panel (HV-REP) is made up of Veterans with lived experience of homelessness. The purpose is to collaborate with NCHAV-affiliated researchers to improve research related to Veterans health, housing, and services. All HV-REP meetings take place virtually by conference call on a quarterly basis and panel members receive an honorarium of $30 per hour for their time.
As part of the panel, you would help promote Veteran-centered research by providing feedback on new and ongoing research and evaluation projects and advice on the use of study results to benefit Veterans. Eligibility criteria:
- Veteran status
- History of homelessness/housing instability, and
- Ability to participate in virtual conference calls
If you are interested and meet all of the eligibility criteria, fill out the PDF application OR the online application. And, if you have any questions at all, please contact us.
Intramural Grants
Each Spring, the National Center on Homelessness among Veterans (Center) typically issues a request for proposals to conduct intramural and collaborative operations-based research projects for each fiscal year (i.e., October – September) based on priorities which have been identified by the Homeless Programs Office (HPO).
Ideally, projects should be completed within 9–10 months following an award, using existing staff, and in collaboration with an operational partner (which can be the Center). Applications must include at least one Core or Affiliate Investigator of the Center (does not need to be the Principal Investigator), but the Principal Investigator must be a VA employee.
If you are interested, please see the brochure for more details on how to apply or contact us with any questions you might have.
