Subject: Roland Bulirsch (1932-2022)


With sadness we have to inform you that Roland Bulirsch (1932-2022)
passed away on 21 September 2022. He followed his beloved wife
Waltraut who died in 2020. Born 10 November 1932 to working-class
parents in Reichenberg (Bohemia), he experienced occupation, war and
expulsion. From 1947 till 1951 he received a professional training as
an engine fitter at Siemens-Schuckert (Nuremberg) and worked there
afterwards as a machinist. In 1954 he finished high school and began
studying mathematics and physics at the Technische Hochschule in
Munich, graduating in 1959. Here he earned a mathematics Ph.D. in
1961 and the habilitation in mathematics in 1965. During his time in
Munich the famous extrapolation algorithms result from a joint
research with J. Stoer. In 1967 he became Associate Professor at the
University of California, San Diego, which appointed him Full
Professor in 1968. Here he developed the multiple shooting algorithm
with applications to space problems as well as arithmetic-geometric
means in elliptic integrals. In 1969 he went to the University of
Cologne as Full Professor, in 1972 he accepted a full professorship at
the Department of Mathematics of the TU Munchen and remained there
until his retirement in 2001.

He was an excellent and inspiring teacher and an enthusiastic
researcher; more than 200 diploma theses, 40 Ph.D. theses and 12 venia
legend theses are witnesses of his enourmous influence. R. Bulirsch
embodied the ideal of a mathematician: He could explain even the most
complicated things simply. He was the author (with J. Stoer) of
Introduction to Numerical Analysis, a standard reference for the
theory of numerical methods. He served as an editor for many
journals. He was a member of the TUM Senate and twice Dean of the
Department of Mathematics For more than a decade he was a referee for
the German Science Foundation and headed the committee for Mathematics
from 1984-1988. R. Bulirsch was always open to political and cultural
questions. He was an expert in orchids, had a deep connection to music
and was highly interested in literature, art and astronomy. We mourn
with his two daughters and his grandchildren.

Subject: PhD Position, Causal AI for Public Health


Structured Graphical Models for Causal Inference is an increasingly
important class of Machine Learning techniques, especially in
applications of public health and medicine. Using careful
well-principled structure in the modeling, conclusions can be reached
regarding the cause-effect, rather than simply correlational
influence, with far reaching implications for understanding and
treatment/policy. The development, analysis, training and inference
of these models is highly nontrivial, and involves an array of tools
from statistics and information theory along with optimization and
numerical analysis. As part of a Horizon Europe EU-wide project, we
are seeking motivated and competent PhD students to pursue research in
the associated fields. As part of this position, we seek a PhD
student with a background in computer science, statistics, and/or
applied mathematics to work on probabilistic graphical models subject
to potentially time varying trends and exhibiting potential for causal
inference. The project will involve developing new models, proving
statistical properties thereof, developing techniques to adequately
train them with strong accuracy and generalization, and testing them
on real biomedical and public health data. The PhD student will be
supervised jointly by Vyacheslav Kunurtsev and Ondrej Kuzelka at the
Czech Technical University in Prague, the Department of Computer
Science. A preference is given to candidates with experience in
programming, especially (but not limited to) Python.
