Subject: John Francis, Co-Inventor of QR

Dear Colleagues,

For many years, I have been interested in meeting J G F Francis, one of
the co-inventors of the QR algorithm for computing eigenvalues of general
matrices. Through a lead provided by the late Erin Brent and with the aid
of Google, I finally made contact with him.

John Francis was born in 1934 in London and currently lives in Hove, near
Brighton. His residence is about a quarter mile from the sea; he is a
widower. In 1954, he worked at the National Research Development Corp
(NRDC) and attended some lectures given by Christopher Strachey.
In 1955,'56 he was a student at Cambridge but did not complete a degree.
He then went back to NRDC as an assistant to Strachey where he got
involved in flutter computations and this led to his work on QR.

After leaving NRDC in 1961, he worked at the Ferranti Corp and then at the
University of Sussex. Subsequently, he had positions with various
industrial organizations and consultancies. He is now retired. His
interests were quite general and included Artificial Intelligence,
computer languages, systems engineering. He has not returned to numerical

He was surprised to learn there are many references to his work and
that the QR method is considered one of the ten most important
algorithms of the 20th century. He was unaware of such developments as
TeX and Math Lab. Currently he is working on a degree at the Open

John Francis did remarkable work and we are all in his debt. Along with
the conjugate gradient method, it provided us with one of the basic tools
of numerical analysis.

PhD position at the Technical University of Denmark

A PhD position for the duration of three years is available
in the area of large-scale algorithms for imaging problems in,
e.g., biometrics and geophysics; see

We will develop and implement the enabling mathematical
technology for next-generation imaging problems arising in
areas such as biometrics, crystallography, geophysics, and
surveillance. We will revisit the original problem
formulations and derive novel and highly-efficient methods
for their solution, using the most recent developments in
mathematics and numerical analysis.

Specifically, the project aims at developing modern and
efficient algorithms for imaging using recent advances in
interior-point algorithm combined with preconditioned iterative
methods for solving structured sets of Newton equations.

The PhD stipend is financed by the Danish Agency for Science,
Technology and Innovation (FTP). The project is a joint
collaboration between the Technical University of Denmark,
Aalborg University, and MOSEK ApS, Copenhagen.

This PhD project is mainly associated with DTU, and the
supervisors are Professor Per Christian Hansen and Associate
Professor Marielba Rojas. This project is expected to start
January 1, 2008. For more informatinon about requirements

Subject: NERC PhD Studentship in Data Assimilation and Stochastic Simulation

The aim of this research project is to develop
effective Bayesian sampling techniques for application
to data assimilation problems arising in the
environmental sciences. Data assimilation aims to combine
information from numerical models with observational data
in order to obtain accurate estimates of the current and
future states of a (possibly stochastic) dynamical system. Sampling
techniques such as MCMC (Markov Chain Monte Carlo) methods
will be investigated. Such techniques are required for
problems that are far from Gaussian and are not amenable
to optimization methods (such as 4D variational methods)
or Gaussian approximations (based on the Kalman filter).
The primary challenge is the construction of proposals
for MCMC methods that are cheap to implement and yet
capture sufficient information to lead to efficient
sampling. The succesful candidate will apply ideas from
reduced order modelling to construct, implement and evaluate
MCMC methods based on such proposals. Applications include
weather forecasting, climate change and oceanography.

The project will be based at either Warwick or Reading
University and will be supervised by Professors Nancy
Nichols (Reading) and Andrew Stuart (Warwick). It is
funded by the NERC Centre of Excellent in Data Assimilation
(DARC) at Reading.

The funding for UK students is for three years at the standard
NERC rate (currently 12,600 GBP in 2007/2008), plus fees.
For EU students only fees are covered.
