Welcome to the Personality, Diversity, & Law (PDL) Lab

Research Interests: For more details, please see my CV.


1. Hate Crimes & Sexual Minority Issues: This area of research addresses legal and clinical issues for lesbian, gay, bisexual, and transgender (LGBT) persons.

Legal Perspectives: With hate crime laws as a back drop, my work examines whether evidence of sexual orientation-based and other minority-based hate serves as an aggravating factor in sentencing. It also examines what juror-related characteristics (e.g., sexual prejudice, authoritarianism) mitigate sentencing decisions. Current work analyzes these questions in jury-eligible samples across Texas and across the country, as well as predictors of support for LGBT-related legislation in general, with particular interests in the need for affect and other emotional characteristics.  Future work will continue emotional theory tests in this context, as well as the development of an attitudes toward hate crimes scale.

Health Perspectives: Of equal importance is the functional impact of hate crime victimization. As such, my research team currently runs the Legacy Project, a grant examining various social and clinical impacts of victimization, as well as contemporary methods of measuring sexual orientation identity. The project also focuses on identification of sexual minority-specific risk and protective factors for future assessment and intervention. Currently in grant application and data planning phases is follow-up work to Project Legacy addressing sexual behavior, mental health, and violence proneness impacts of sexual assault, hate crime and stalking victimization.

2. Suicide: This domain of my work broadly addresses two issues: Testing risk prediction models of suicide proneness in vulnerable populations, and training mental health professionals in suicide risk assessment and management competencies. Current emphases in suicide risk models focuses on integration of personality, internalized prejudice, and/or the Interpersonal Theory of Suicide in multiple samples.  Currently in planning is a multi-site study to examine the need for affect with trait and interpersonal characteristics as predictors of suicide proneness over time.  I also address clinician-related topics such as beliefs about suicide and addressing the need for training in suicide risk assessment. Immediate directions include a multi-site study evaluating the impact of classroom- and workshop-based methods of training. 

3. Witness Testimony/Trial Consultation: This line of research examines mechanisms associated with the credibility and effectiveness of witness testimony. Prior research focused on witness-related characteristics such as confidence, credibility, self-efficacy, and others. Additionally, juror traits and attitudes such as the Five-Factor Model and need for affect are examined as moderating variables of jury decision making. Recent work in this area has evaluated conceptual distinctions between witness credibility, efficacy, and personality, as well as perceived similarity with expert witnesses.  Future directions may include further development of the Witness Self-Efficacy Scale, qualitative studies testing theories of jury deliberation, and evaluation of self-efficacy based models of witness preparation. 

***For any interested students, please note I will be focusing my work on the hate crimes/sexual minority issues and suicide domains moving forward.  I will not pursue trial psychology research unless it stands to make a significant contribution to the field (e.g., empirical investigation of witness preparation models).

***A few doctoral students currently participate in extern trial consulting placements. Although these are not regularly established training sites for the department, I expect applied trial consulting experience to continue for interested students.
