Prof. Joshua Weitz will serve as the chair for a week-long, interactive course entitled ‘Quantitative Phage-Bacteria Dynamics Across Scales’, to be held in Paris this summer. Hosted by the Q-Life Institute at Paris Sciences et Lettres (PSL) University, a public research university based in Paris, France, the course will take place from July 8-12. This […]
Quantitative Biosciences Textbook and Lab Guides Now Available
After nearly 10 years in development, the textbook “Quantitative Biosciences: Dynamics across Cells, Organisms, and Populations” and associated lab guides are now available to order from Princeton University Press and Amazon. Written by Prof. Weitz, the book serves as “a hands-on approach to quantitative reasoning in the life sciences.” Combined with companion guides in MATLAB, […]
Consider Supporting Our Research
Consider gifting to the Quantitative Viral Dynamics (QVD) Research Fund to support the professional development of students and early career researchers in the Weitz Group, who work to understand how viruses impact human and environmental health. Your gifts will support advanced training, networking events, and professional travel to conferences and peer institutions, as well as […]
Launch of the COVID-19 Immunity Estimator
Did you know that protection against COVID-19 weakens over time? Researchers in the Quantitative Viral Dynamics group have contributed to the development of the COVID-19 Immunity Estimator to help communicate this knowledge to the public. The COVID-19 Immunity Estimator is designed to provide personalized estimates of protection against infection, and against severe disease based on […]
The Weitz Group Moves to the University of Maryland
After over 15 years at the Georgia Institute of Technology, Prof. Weitz and his research group have moved to the University of Maryland. Weitz joins UMD as a professor of biology and the Clark Leadership Chair in Data Analytics. In a press release published by UMD’s Department of Biology, Weitz shared the following: “Given my […]
Prof. Weitz Serves as New Co-Chief Editor of Journal of Theoretical Biology
Prof. Weitz is now one of the chief editors of the Journal of Theoretical Biology. In this role, Weitz will advise on new directions for the journal, identify new topics for publication, write editorials, and more. Learn more about the editorial board here.
Virivores, the organism can eat up to a million viruses a day
Prof. Weitz was recently featured in EL PAÍS as an expert reference on why microbes may be motivated to consume viruses. “Because viral genomes are relatively densely packed – and because genetic material is rich in phosphorus – viruses have higher phosphorus content than typical microbes. Therefore, they might have a nutritional bonus.” — Joshua […]
Bacteria-Virus Arms Race Provides Rare Window into Rapid and Complex Evolution
This press release was originally published on https://today.ucsd.edu. As conceived by Charles Darwin in the 1800s, evolution is a slow, gradual process during which species adaptations are inherited incrementally over generations. However, today biologists can see how evolutionary changes unfold on much more accelerated timescales. Rather than the evocative plants and animals of the Galapagos […]
Collaborative Paper Published in Science
Look for our new paper out in Science, titled “Rapid bacteria-phage coevolution drives the emergence of multiscale networks.” This work is was done in collaboration with Justin Meyer and his group of researchers from the University of California in San Diego. The editor’s summary of this article reads: Real communities are characterized by complex interaction […]
