  • Biography

    Brian Winkel earned his degrees in mathematics (:BS, MS, PhD) in 1964, 1967, and 1971, respectively, with his PhD from Indiana University in Noetherian Ring Theory. While teaching in his first position (liberal arts college Albion College, Albion MI USA) he developed an interest in applications of mathematics to biology and while teaching in an engineering setting (Rose-Hulman Institute of Technology, Terre Haute IN USA, United States Air Force Academy, USAFA CO LUSA, and United States Military Academy, West Point NY USA)  he developed a strong interest in engineering applications of mathematics. With sabbatical experiences at Michigan Technological University, Houghton MI USA and Brown University, Providence RI USA he strengthened his commitment to teaching mathematics using applications to introduce and drive the learning process.

    Along the way he founded and edited three journals Cryptologia (1977 - Present), Collegiate Microcomputer (1982-1993), and PRIMUS - Problems, Resources, and Issues in Mathematics Undergraduate Studies (1990 - Present).

    Upon retirement from the United States Military Academy in spring 2011 he committed time, energy, and resources, and together with many very talented colleagues who possessed the same vision of teaching modeling first differential equations he founded SIMIODE - Systemic Initiative for Modeling Investigations and Opportunities with Differential Equations at

    SIMIODE received a three year National Science Foundation DUE Grant on 15 March 2018 to support the overall mission of SIMIODE and offer Developer workshops for colleagues who wish to write and contribute Modeling Scenarios to SIMIODE resources and Practitioner workshops for those who wish to learn how to do modeling to motivate and teach differential equations.

    SCUDEM - SIMIODE Challenge Using Differential Equations is an annual event offered by SIMIODE in which three member student teams of high school and undergraduate students select one of three problems areas (a) physics/engineering, (b) chemistry/life sciences, or (c) social sciences. They then work on the model at their home institution for a week and gather at a local site near their home school to share and be judged on their presentation. Complete details on SCUDEM are here,
