Dr. Halliday’s research interests broadly pertain to understanding, preventing, and addressing racial/ethnic disparities in antisocial behavior, other mental health problems, and substance use children and adolescents. Her particular areas of interest are in 1) the effects of direct and vicarious racial/ethnic discrimination on youth mental health and behavior outcomes and the mechanisms these effects, and 2) schools as well as contexts for interventions to reduce racial/ethnic disparities in youth mental health and behavior outcomes. Dr. Halliday has received funding both as a principal investigator and as a co-investigator from the National Institute on Minority Health and Health Disparities (NIMHD), the National Institute of Mental Health, the National Institute on Drug Abuse, the National Institute of Justice, the Institute of Education Sciences, the Patient-Centered Outcomes Research Institute (PCORI) and the William T. Grant Foundation, and has collaborated on several other research projects funded by National Institutes of Health and other agencies. Currently, she is principal investigator or co-principal investigator on three school-based randomized trials:  1) a study funded by the William T. Grant Foundation to examine the effects of training teachers in unconscious racial bias on student academic and behavioral outcomes; 2) an NIMHD-funded R01 trial to test the effects of integrating a multilevel intervention to address racial/ethnic discrimination into violence prevention as a means to reduce disparities in youth violent/aggressive behavior; and 3) a study funded by the Patient-Centered Outcomes Research Institute to examine the enhancements to school-wide mental health screening practices as a means to reduce unmet mental health needs in African American children.


Dr. Halliday currently serves as the co-Director of Research Training for the Charleston Consortium Psychology Internship Training Program as well as a co-Director of the Diversity in Addiction Research Training Program.
