Presentations and Policy
The work done by Dr. Christine Kreuder Johnson and the EpiCenter team has far-reaching influence within and beyond the realm of academia. Disease emergence, spillover, and subsequent spread in human populations are inextricably tied to the health of animals and our environment. The need for research to inform science and policy remains pressing, now more than ever, in our era of a rapidly changing environment and shifting landscape use at the animal-human interface.
Through commentary pieces, conference presentations, epidemiological support, congressional briefings, and invited testimony to state and federal governments and intergovernmental international partners, we work to support science-based decision-making and public policy at home and all around the world.

Research and publications produced by the EpiCenter team influence and help shape policy for national and international agencies and are frequently cited as key evidence and resources.

Wastewater-based Disease Surveillance for Public Health Action
Produced by the National Academies of Science, Engineering, and Medicine at the request of the CDC, this consensus study report reviews the usefulness of community-level wastewater surveillance during the pandemic and assesses its potential value for the control and prevention of infectious diseases beyond COVID-19. – February 2023

A Global Early Warning System for Pandemics: A Blueprint for Coordination
A review by the Milken Institute of the US approach to pandemic preparedness and the resulting impact on Covid-19 responses in order to identify and prioritize the needed next steps to address future pandemic threats, as envisioned in the report ‘A Global Early Warning System for Pandemics: Mobilizing Surveillance for Emerging Pathogens’. – March 2022

A Global Deal for Our Pandemic Age
A paper co-authored by Dr. Johnson served as a key resource in the preparation of this 2021 report by the G20 High-Level Independent Panel on Financing the Global Commons for Pandemic Preparedness and Response. The paper ‘Preventing the next pandemic: the power of a global viral surveillance network’ analyzed current systems and called for a global viral surveillance network. – June 2021
Featured Presentation
Hosted by the UC Davis Office of Research, Dr. Christine Kreuder Johnson, Dr. Tierra Smiley Evans, and Dr. Pranav Pandit of the EpiCenter, joined by Dr. Cristina Davis, Dr. Jonathan Eisen, and Dr. Zhaodan Kong, spoke on a trans-disciplinary panel discussing the future research needed to address the technical and scientific challenges for pandemic preparedness.
