The workshop will feature a series of expository talks by UCSD postdocs and faculty on the fundamentals of optimization, differential equations, quantitative image processing, and genomic data analysis. Topics will include the formulation of advanced optimization algorithms, numerical methods for solving differential equations, differential-equation-based image analysis, and data analysis. The workshop is intended for both undergraduate and graduate students. Funding is available for travel and lodging. Underrepresented minorities and women are particularly encouraged to register for the workshop. There will be no registration fee.

Unlike papers and poster presentations, a Doctoral Showcase poster (called a thesis canvas) highlights the entire contents of a dissertation, including previously published results, to allow for a broad perspective of the work. The Doctoral Showcase provides a unique opportunity for students nearing completion of their PhD to present a summary of their dissertation research in the form of talks and posters, and network with prospective employers. Please see https://sc18.supercomputing.org/submit/showcases-submissions/#section1 for details on submissions.

The Firedrake project brings a radical new approach to simulation software development. Instead of painstakingly hand-coding highly sophisticated algorithms one PhD at a time, Firedrake models the simulation creation process as a sequence of mathematical abstractions and develops specialised compilers to automatically translate from one to the next, thereby automatically generating high performance parallel code from a high-level specification of the original mathematical problem. This position represents the opportunity for a computational scientist to create new abstractions and implementations resulting in new simulation capability with immediate impact over a diverse user base. The successful candidate will play an important role in the heart of the Firedrake project while enjoying considerable freedom to develop their own programme of computational science research based around the further development of Firedrake.

The projects are embedded in the field of modern inverse problems and introduce a new innovative perspective into the education of future scientists and engineers. The advertised position is associated with the project "Model order reduction for goal-oriented Bayesian inversion," and is advised jointly by Prof. K. Veroy-Grepl at RWTH Aachen and Prof. T. Bui-Thanh at UT Austin. In this project, we focus on goal-oriented Bayesian inversion of problems governed by parametrized partial differential equations, particularly for applications involving high-dimensional parameter spaces. The research goals of this project are: - Reduction of the computational cost to solve Bayesian inverse problems governed by partial differential equations. - Quantification of the uncertainty caused by the use of surrogate reduced-order models. - Application to large-scale inverse problems with high-dimensional parameter spaces, e.g., in the geosciences. Our offer: The candidate will be a regular employee and must meet required personal qualifications. This is a full-time position with a civil service pay scale TV-L E13. The expected appointment period is three years starting October 2018. Full involvement in the IRTG activities, including joint RWTH-UT colloquia, annual workshops and schools, and short courses is expected. A six- month research stay at University of Texas in Austin is part of the training program. Applications are being reviewed now until the position is filled. Your profile: Requirement for this position is a master's degree in computational engineering science, engineering, applied mathematics, computer science, physics, or a similar subject with a superior academic record. Practical programming experience in Matlab, Python, C, or C++ is advantageous. Excellent written and spoken English language skills are required.
