Subject: James Hardy Wilkinson centenary

September 27, 2019 is the 100th anniversary of the birth of James
Hardy Wilkinson FRS (September 27, 1919--October 5, 1986).

We have collected various kinds of information about Wilkinson at

The page includes
- biographical articles,
- audio of a 1976 interview with him,
- videos of Wilkinson (and Cleve Moler) speaking at an Eigensystem
Workshop held at Argonne National Laboratory, Illinois, USA, in

In addition, videos from the first day of talks at the conference
"Advances in Numerical Linear Algebra: Celebrating the Centenary of
the Birth of James H. Wilkinson" (May 2019, Manchester) are available at

Subject: New Book, BEM-based Finite Element Approaches on Polytopal Meshes

BEM-based Finite Element Approaches on Polytopal Meshes
by S. Weisser
Lecture Notes in Computational Science and Engineering Vol. 130
Springer International Publishing, 2019

This book introduces readers to one of the first methods developed for
the numerical treatment of boundary value problems on polygonal and
polyhedral meshes, which it subsequently analyzes and applies in
various scenarios. The BEM-based finite element approaches employs
implicitly defined trial functions, which are treated locally by means
of boundary integral equations. A detailed construction of high-order
approximation spaces is discussed and applied to uniform, adaptive and
anisotropic polytopal meshes.

The main benefits of these general discretizations are the flexible
handling they offer for meshes, and their natural incorporation of
hanging nodes. This can especially be seen in adaptive finite element
strategies and when anisotropic meshes are used. Moreover, this
approach allows for problem-adapted approximation spaces as presented
for convection-dominated diffusion equations. All theoretical results
and considerations discussed in the book are verified and illustrated
by several numerical examples and experiments.

Given its scope, the book will be of interest to mathematicians in the
field of boundary value problems, engineers with a (mathematical)
background in finite element methods, and advanced graduate students.

Subject: Postdoc Position, Computational Math, Boston Univ

Applications are invited for a postdoctoral position in the research
group of Prof. Samuel Isaacson in the Department of Mathematics and
Statistics at Boston University. This position is from a recently
funded NSF grant to develop stochastic reaction-drift-diffusion
methods for studying T cell signaling dynamics in realistic cellular
geometries. The project will involve both the development of new
particle-based methods for simulating spatial transport and reactions
within cells, and the development of mathematical models for T cell
signaling in collaboration with experimentalists. The former involves
the continuing development of accurate analytical and numerical
methods for approximating the solutions to very high dimensional
coupled partial-integral differential equations using stochastic
methods. Applicants interested in either numerical method development
or mathematical modeling are invited to apply.

Applicants should have a background in mathematical biology,
biophysics, scientific computing, computational physics, numerical
analysis or related areas. As many planned simulations require solving
computationally expensive PDE and particle models, expertise in a
compiled language is required (C, C++, Fortran or Julia). No previous
experience in T cell modeling is required.

Applications should be submitted through Mathjobs at

and include a CV, a research statement, and three letters of
recommendation. The start date is flexible, but not before summer
2020. Review of applications will be ongoing until the position is
filled. For more information about this position please contact

research in two directions: improving optimization aspects for
efficient deep learning, and employing statistical machine learning
techniques for improving the scalability of optimization methods for
difficult problems.

Date: September 25, 2019
Subject: Postdoc Position, Uncertainty in digital twin engineering, Univ of Liverpool

Computer model predictions of prototypes are only as good as their
underlying assumptions. Design decisions need to account for
manufacturing and environmental uncertainties in a robust yet
efficient manner. Robust to uncertainties safe-guards designs against
unlikely but possible scenarios, yet an overly conservative design
undermines efficiency. A balance between robustness and efficiency is
essential, which requires uncertainties and their effects to be
properly quantified so that risk-informed and defensible design
decisions can be made.

This research project is funded in support of a multi-disciplinary
EPSRC program grant for digital twins for improved dynamic design. Key
questions fundamental in establishing a practical digital twin
framework include:
(1) How do we decide which engineering and scientific models to use?
(2) How do we quantify the uncertainties in the models' inputs, and
the uncertainties in the form of the models themselves?
(3) How should models be validated against empirical observations?
(4) How can we interpret the model output to make an engineering

These questions will be addressed through comprehensive uncertainty
quantification that respects the distinction between two main kinds of
uncertainty: aleatory uncertainty, which stems from stochasticity or
variability across space, time or components; and epistemic
uncertainty, which stems from imprecision or incertitude about
conditions, parameters, or model structure that arises from incomplete
knowledge. The project will combine sampling-based strategies such as
Monte Carlo simulation and constraint analysis such as interval
bounding and projection.

The project will develop strategies that work efficiently and scalably
with aleatory, epistemic, and mixed uncertainties. More information
about the project consortium can be found at
