Courses to be determined

Spring 2015

COURSE 560.660 - Modeling Complex Systems Colloquium: Course will address various themes related to modeling complex systems through critical evaluation of technical articles, open discussion, faculty presentations, and computational workshops. Teams of 3-5 faculty will develop monthly units based on different themes, examples of which may include: optimization and uncertainty modeling in science and engineering, particle-based modeling, experimental and field measurements in multi-scale models, linking atomistic to-continuum-scale models, challenges in climate and ocean modeling, homogenization and upscaling of small-scale data. This course is a requirement for MCS IGERT Trainees, but it is open to all graduate students.

Elective Course: Graduate-level Probability/Statistics Course (must be approved by the IGERT Director)

Advanced Communication Course: Choice of any (2) seven-week module offered by the JHU Center for Leadership Education

COURSE 560.660 - Modeling Complex Systems Colloquium: Course will address various themes related to modeling complex systems through critical evaluation of technical articles, open discussion, faculty presentations, and computational workshops. Teams of 3-5 faculty will develop monthly units based on different themes, examples of which may include: optimization and uncertainty modeling in science and engineering, particle-based modeling, experimental and field measurements in multi-scale models, linking atomistic to-continuum-scale models, challenges in climate and ocean modeling, homogenization and upscaling of small-scale data.

COURSE 550.695 - Advanced parameterization in science and engineering (Instructor: Greg Eyink) This course will present an overview of topics in science-based parameterization, including dynamics, probability, and other applied mathematical methods. These concepts will be presented in a unified format, with some emphasis on scientific computing. Specific topics include: basic probability, statistical dynamics (moment hierarchies, Liouville/forward equations, path-integral methods), asymptotic closure (homogenization, Chapman-Enskog), closure techniques without any separation of scales (nonlinear Galerkin & weighted residuals, algebraic closures, PDF-based closures, down-scaling), uncertainty quantification (variance & other measures of uncertainty, Bayesian estimation, ensemble methods), hybrid methods.
