Announcing calls for applications from MS + PhD students + postdocs: Summer School on Quantitative Phage-Bacteria Dynamics Across Scales, U of Maryland, College Park, June 23-27, 2025 Phage transform the fate of cells, populations and ecosystems. This summer school will bring together thought leaders in integrating models, experiments, and field data in dialogue with early career researchers to learn fundamentals and cutting-edge advances in the study of phage-bacteria dynamics across scales. The course will include thematic days spanning cellular mechanisms, phage therapy, spatial dynamics, evolution, and ecosystem functioning. Each day will include (i) morning lectures; (ii) afternoon computational labs; (iii) evening plenaries or poster sessions. Students will learn how to model phage-bacteria across scales, integrate computational methods into research practice, and bridge the gap between models and data with case-study problems. Our aim is to foster dialogue between early career trainees and thought leaders in the quantitative study of phage-bacteria dynamics across scales. The school is limited to 25 participants. No registration fee for accepted students and *travel awards are available*. Application date: March 21, 2025 Application site: https://bit.ly/phageschool2025-umd Applications should include a CV, motivation letter and support letter. Registration is free for accepted students and travel awards are available.
