The Society for Industrial and Applied Mathematics (SIAM) has launched the latest addition to its family of premier applied mathematics journals – SIAM Journal on Life Sciences (SIALS) -- and Pitt Professor Jonathan Rubin is the founding editor-in-chief. SIALS will provide a high-quality publication platform for research that features the substantive use of quantitative methods—including modeling, computing, and mathematical analysis—in the study of biological systems and their applications. Articles in SIALS will showcase the development of new mathematical models of biological systems, and/or the development and application of new quantitative methodology or sophisticated existing mathematical methodology for the analysis of such models. SIALS began accepting submissions in July 2025 and aims for publication of its first issue in early 2026. https://www.siam.org/publications/siam-journals/siam-journal-on-life-sciences/
