Research Interests

I am a prevention scientist who focuses on translating basic research in developmental neuroscience to interventions for child and adolescent social-emotional, behavioral, and physical health. Of primary interest is the development of executive function, the set of neuro-cognitive skills mediated by the prefrontal cortex that encompass self-regulated decision-making and goal-oriented problem-solving. My basic research has demonstrated that disruptions in the development of executive function can be an important contributor to patterns of childhood and adolescent aggressive and depressive problems (Riggs, Blair, & Greenberg, 2003), substance use (Riggs, 2015), and obesity (Riggs et al., 2014).

I translate this research into developmentally-timed school and after-school based interventions for young people. The neural systems of the brain responsible for executive function proceed through rapid stages of growth in childhood and adolescence. This provides a window of opportunity to implement interventions that take advantage of neurodevelopmental processes, potentially leading to larger and more sustained intervention effects. To this end, I am currently testing the efficacy of ME Moments, a school-based approach to substance use prevention which combines traditional strategies for promoting social-emotional competence and executive function with mindful awareness practices.

I am also currently the Co-Principal Investigator for the Advancing Innovation and Dissemination of Evidence-Based Action in Schools (IDEAS) for Health project, a multi-university research partnership established to support local school district comprehensive health and wellness. IDEAS is part of a larger statewide systems approach, which combines efforts from several statewide stakeholders to work with Colorado school districts on developing and implementing comprehensive health and wellness programs. A primary aim of IDEAS is to generate and sustain comprehensive school health innovation through an Innovation Lab, where school communities identify and test innovative strategies to promoting comprehensive health and wellness.

Finally, I direct the CSU Cannabis Research Group (CGR), which consists of faculty from HDFS, Psychology, and Social Work. The CRG conducts research on marijuana use etiology, prevention, and policy, and disseminates marijuana research to academic and community stakeholders. Two CRG research projects are currently underway. One is testing a personalized normative feedback approach to preventing heavy marijuana use among college students (PI: Riggs). A second is testing associations between changes in state marijuana use policy across 11 states on adolescent and those identifying as LGBTQ (PI: Conner, Co-I: Riggs).
