Tsai Lab



Our group is involved in numerous, diverse projects all thematically related to understanding and providing services for disadvantaged populations, including those who are homeless and/or have severe mental illnesses. Much of our work is focused on the veteran population and can be characterized as health services research. We have access to large databases and nationally representative samples. We always welcome collaboration and look for students and fellows interested in working with us. Feel free to contact us.




What is Project HALT? Ending homelessness requires efforts to prevent individuals from ever entering homelessness (i.e., prevention or diversion). PROJECT HALT is a clinical trial to investigate the science of homelessness diversion including when and for whom it works best and how we can continue to strengthen diversion efforts (e.g., tailoring it to sexual and gender-minoritized communities). Our research team is reaching out to select individuals as they exit emergency departments to screen their housing status. Individuals at risk of losing housing will be randomized to receive homeless diversion or standard care. Both groups will be followed over six months and health and housing outcomes will be assessed. Project HALT is a collaboration between the UTHealth Houston School of Public Health, Harris Health System, and the Coalition for the Homeless of Houston/Harris County.

Veterans will participate in financial education groups, individual financial coaching, and computerized budget assistance tailored to their needs and experiences. The goal of the grant is to provide financial counseling to 100 veterans experiencing or at risk for homelessness, increase their financial literacy and money management skills, and improve their well-being and quality of life.
