Our research draws from biomedical informatics and the related field of biomedical data science, to address the challenge of how to incorporate technology and digital approaches into translational research, precision medicine, and precision public health practices.

- Biomedical Informatics, Data Science, and Implementation. Biomedical Informatics can be defined as the analysis, management and use of knowledge, information and data in the domain of biomedicine and health. (Kulikowski et al. JAMIA 2012). Biomedical informatics and the related subfield of biomedical data science is concerned with discoveries using primarily health data. (Brennan et al. JAMIA 2017). Biomedical informatics often involves the implementation of tools, resources, and organizational models that transform translational research (moving theory into practice and concepts into reality). (Description used by 2019 AMIA Informatics Summit Implementation Track).
- Translational research may be conceptualized as four phases revolving around the development of evidence-based guidelines (T1-T4). T1 research seeks to move a basic discovery into a candidate health application (e.g., genetic test/intervention); T2 research assesses the value of a health application leading to the development of evidence-based guidelines; T3 research attempts to move evidence-based guidelines into health practice; and T4 research seeks to evaluate the "real world" health outcomes of a health application in practice. (Khoury et al. Genet Med 2007). Translational research can lead to actionable health discoveries that provide relevant information for precision medicine and precision public health.
- Precision medicine “is the practice of clinical decision-making such that the decisions maximize the outcomes that the patient most cares about and minimize those that the patient fears the most, on the basis of as much knowledge about the individual’s state as is available.” (Pauker SG et al. NEJM. 1987). This definition of precision medicine captures a focus on the outcomes of care, the central role of the patient in defining important outcomes, and the inclusion of a broad personal data. (Williams MS. In: Personalized and Precision Medicine Informatics. Springer. 2020).
- Precision public health involves collecting and using more accurate data on genes, exposures, behaviors, and other social/economic health determinants in order to enhance public health action that can lead to improved health and reduced health disparities in subpopulations. (Khoury et al. Am J Prev Med. 2016).
Evidence for Precision Medicine and Precision Public Health Practice
Projects that seek to leverage EHR-derived data and other data sources to identify practice patterns and behaviors relevant to health outcomes. Our goal is to generate evidence to guide precision medicine and precision public health practices in areas such as case management after the return of genomic test results, chronic disease management, drug treatment selection, and postpartum care optimization.

Facilitating Translational Research with Digital Devices
Characterizing and designing services to enable participation and engagement in research using digital devices. Our goal is to provide tools to help researchers make use of emerging technologies such as wearable monitoring to enable deep phenotyping, while keeping study participants at the center of innovation.

Genomic Clinical Decision Support
Approaches to design and evaluate genomic clinical decision support leveraging local health IT infrastructure. We also have contributed to the NHGRI-funded eMERGE Network EHR Integration workgroup that is developing methods and best practices for incorporating patient’s genomic data into the EHR and assessing the usability of those data by physicians and patients (see Projects).
