Subject: ICERM, Time-Dependent PDE Discretizations, USA, Jan 2022

This workshop aims to spur a holistic approach to the design of time-
dependent PDE discretizations, particularly in terms of developing
time integration techniques that are intertwined with spatial
discretization techniques, focusing on: generalized ImEx methods,
asymptotic- preserving and structure-preserving methods, methods that
exploit low- rank dynamics, analysis of order reduction, parallel in
time methods, and performant, maintainable, extensible software
implementations. This workshop runs from January 10 through January
14, 2022.

We are calling for applications for a PhD position in the Applied
Analysis (AA) group at University of Twente (UT)'s Department of
Applied Mathematics to work in the area of physics-informed machine
learning.  Research activities of this PhD position focus on the
synergistic integration of modern numerical methods for PDEs and
recent machine learning techniques, especially based on artificial
neural networks and Gaussian processes. The successful candidate will
develop physics- informed machine learning methods towards real-world
engineering and/or medical applications. Such research initiatives
address the drawbacks of conventional numerical methods and seek to
enable data- enhanced predictive modeling through model order
reduction, multi- fidelity data fusion, and machine learning.

We look for an enthusiastic individual who is driven by curiosity and
has: (i) or will shortly acquire, a master's degree in applied
Mathematics, computational science or engineering; (ii) knowledge in
machine learning and/or uncertainty quantification; (iii) experience
with numerical methods for solving PDEs; (iv) demonstrated programming
skills; and (v) good communication skills in a collaborative working
environment.  In addition, knowledge in applied mechanics would be an
advantage.  Working language at the University of Twente is
