Paper on the effectiveness of Georgia Tech’s Covid-19 surveillance testing program published in Epidemiology

February 8, 2022 by adavidson38 Leave a Comment

In early 2020, members of the Weitz Group were part of a dedicated team of Georgia Tech researchers, engineers, campus leaders, and staff members working to establish Georgia Tech’s surveillance testing program. The goal of the program was to use testing to reduce the spread of Covid-19 and increase campus safety.

A collaborative paper on the effectiveness of the surveillance testing program is out now in Epidemiology. In addition to Prof. Weitz, research scientist Stephen Beckett, Ph.D., collaborative group member Conan Zhao, and former member Ashley Coenen, Ph.D. were involved in the project.

In collaboration with 13 other institutions, new work investigating changes in microbial metabolism with the diel cycle has been published in Nature Ecology and Evolution. Led by Prof. Weitz, group members Daniel Muratore, who served as one of three co-first authors, Stephen Beckett, Ph.D., and Rogelio Rodriguez-Gonzalez contributed to this work.

New paper on assessing population immunity to Covid-19 published in Annals of Epidemiology

September 9, 2021 by adavidson38 Leave a Comment

In collaboration with Benjamin Lopman‘s group at Emory University, our recent work entitled “A framework for monitoring population immunity to SARS-CoV-2” was published in Annals of Epidemiology. The proposed framework suggests combining records of vaccinations and natural infections to assess immunity to Covid-19 at the population level. A dashboard was also created to track estimates of population immunity at the state level.

In collaboration with researchers from Georgia Tech, Brown University, and the Technical University of Denmark, Prof Weitz has published a new paper entitled “Heterogeneity in susceptibility dictates the order of epidemic models” in the Journal of Theoretical Biology. This work examines the complicated relationship between susceptibility to infection and infection spread in epidemics, highlighting the need to “examine the shape of susceptibility in natural populations” to improve epidemic models.
