Paris Sciences et Lettres (PSL) University hosted a winter school centered around Quantitative Viral Dynamics Across Scales. Organized by Prof. Weitz, the school ran for one week (March 21-25, 2022) in Paris, France, and aimed to “bring thought leaders in dialogue with the next generation of early-career scientists to advance the integrative study of quantitative viral dynamics across scales.” Prof. Weitz also served as a lecturer and Scientific Committee Chair. Other guest lecturers include Weitz Group research scientist David Demory, postdoctoral fellow Jacopo Marchi, and several group collaborators.
