About Us

The Precision Public Health Network (PPHN) is an international, transdisciplinary community dedicated to advancing the research agenda for precision cancer prevention and control. Funded by the NIH (R13), our network serves as a collaborative hub for researchers to develop the methods and evidence needed to integrate genomics into population-level health. We move beyond traditional public health models by fostering global partnerships that focus on implementation science, health equity, and the practical application of precision tools.

Our Values

Our Faculty

Our faculty provides a global platform for early-career investigators to lead the development of the precision public health research agenda. We focus on building transdisciplinary capacity through an international network that bridges the gap between genomic discovery and community-level cancer control. By prioritizing implementation science, health equity, and professional mentorship, our experts facilitate the collaborations necessary to move precision health from theory into sustainable public health practice.

Wake Forest University

Social and behavioral scientist with expertise in the implementation of evidence-based research to advance precision public health initiatives. She is a thought leader in the field of precision public health, with her work highlighted in Nature and Harvard Public Health Magazine. Her overarching research goal is to support the translation of genomics applications to maximize population health impact and improve health equity. To achieve this goal, Dr. Allen focuses on contributing to the field in three key areas: 1) participatory implementation science to support community engagement in genomics and precision public health research, 2) workforce diversity through the training of community health workers in genomics research competencies, and 3) novel approaches to communicating genomic information among diverse populations (e.g., risk communication, results disclosure, family health history). Dr. Allen is also a dedicated mentor who is passionate about training the next generation of scientists in the field of precision public health.

Washington University in Saint Louis

Dr. Baumann’s research agenda focuses on the intersection of implementation science, adaptation science, and healthcare equity. She works to identify strategies that facilitate the implementation of evidence-based interventions in low-resource settings and historically underserved populations, nationally and globally. In her national and global work, she has collaborated with several investigators in adapting and implementing evidence-based interventions in usual care, in different settings and with different disease areas. Specifically, to translational research, or the research that aims to turn observations from laboratories, clinics and communities into interventions and practices that improve the health of individuals and public, she has worked in the context of sickle cell, mental health and cancer.
