Implementation Resource for Translational and Human Exposure Research (IRTH)

formerly known as: Human Subjects and Population Exposure Resource


The IRTH leverages SWEHSC human studies and exposure assessment experts to provide a central resource for research consultation and support to investigators sampling Southwest human populations and their living environment. In addition, IRTH scientists assist environmental health science researchers to build translational collaborations from basic science to public health interventions. The goal of IRTH is to help support investigators across and around the rings of the NIEHS Translational Framework.

Key functions of IRTH are to identify local government, health, cultural, or thought leaders in Southwest communities to better engage participants and to provide ‘boots on the ground’ assistance to identify, recruit, and enroll research participants through collaborations with community health centers and organizations.

This provides SWEHSC investigators with: 

  1. Strategies for community engagement to ensure stakeholder buy-in and participant recruitment.
  2. Scientific guidance and practical assistance with methodologies for exposure estimation and measurement. These include exposure modeling, GIS techniques, and sampling of environmental media (e.g. air, water, dust, soil) and human biomarkers.
  3. Experience in the implementation of community-engaged research, including consultation on internal and external regulatory requirements. 
  4. Assistance with designing studies aimed at understanding biological mechanisms of findings from epidemiological studies and designing human studies to assess interventions aimed at reducing the impact of environmental exposures based on findings from mechanistic studies. 
  5. Help in identifying collaborators to conduct translational environmental health research.

Further, IRTH helps identify important exposure concepts that promote an understanding of exposure science for use in the translation of results to the community by the SWEHSC Community Engagement Core. Mentoring and guidance on technical aspects of projects important to Southwestern underserved populations will build trust and technical skill capacity among community scientists and leaders and promote environmental health literacy among community members. The IRTH interacts directly with community members through training events, teach-ins, sampling consultations, identification of analytic laboratories, interpretation of data, and intervention development and implementation. In this regard, the resource is involved in building community capacity among diverse populations in the Southwest to reduce environmental health disparities.

PROJECT CONSULT: The IHS Pathway to Project Support

The IRTH has developed a structured approach to providing assistance for projects receiving subsidized support, to ensure that the best delivery of support results in successful research outcomes.
