Laurence Dixon
I am sad to be passing on news of the death, in August 2023, of
Professor Laurence Dixon, formerly of the Numerical Optimisation
Centre at the University of Hertfordshire in the UK.

Between 1970 and the early 2000s Laurence made many important
contributions to the theory and application of optimisation techniques
-- at that time a new and rapidly developing subject area. The result
which probably attracted most attention was his 1972 proof that if
exact line searches are used then all quasi-Newton methods are
equivalent -- which put rather a damper on some lively ongoing debates
about the merits of rival algorithms!

Laurence's numerous research publications spanned both constrained and
unconstrained optimisation applied to smooth and non-smooth problems.
He-was involved in many industrial and scientific projects, mainly in
the field of aerospace; and he played an important pioneering role in
the introduction of automatic differentiation techniques and in the
early applications of neural networks.

Laurence was also an excellent teacher and an encouraging and patient
research supervisor. Many of his PhD students have gone on to their
own distinguished academic careers.

Laurence's deep Christian faith led him to study for ordination as a
minister in the United Reformed Church and for the last few years
before his final retirement from academic life his time was split
between his research and his role as pastor at a local fellowship..

Laurence will be much missed by friends, collaborators and former
colleagues both in England and also around the world.

Subject: CUQIpy Training Course, DTU, Denmark, Dec 2023

We organize a 2-day training course at the Technical University of
Denmark (DTU) focusing on our python software package CUQIpy for
Computational uncertainty quantification (UQ) for inverse problems.
After completing the course, participants will be able to use CUQIpy
to model statistical inverse problems and perform UQ on them.

CUQIpy is developed as part of the CUQI project, funded by the Villum
Foundation, see Both the software and the
course are aimed at non-experts in Bayesian inverse problems. For more
details, see

In the course, we give a brief introduction to statistical inverse
problems and UQ. This is followed by hands-on tutorials (bring your
laptop!) on the software and its capabilities for modeling and
performing UQ on inverse problems, with examples from image deblurring
and X-ray CT as well as inverse problems based on PDEs. The rest of
the course is devoted to working on a small use-case with CUQIpy and
participants are encouraged to bring their own case and data.

The course takes place at DTU's campus in Lyngby, north of Copenhagen.
We start Thursday, Dec. 7 at 9am and finish around 3pm Friday, Dec. 8.
There is no registration fee. Participants will cover their own travel
and accommodation. A convenient option is the Zleep Hotel Lyngby
across from campus:

To register for the course, please send an email message to us.
