[DMANET] open PhD positions for ERC project: Breaking new ground with Self-Adjusting Networks

Dear all,

We are looking for a highly motivated and bright PhD student with a strong
expertise and interest in graph and network algorithms in particular, and
in theoretical computer science in general, to join our team around the ERC
project AdjustNet.

The goal of our research is to lay the theoretical foundations of
self-adjusting networks: networks ("graphs") whose topology adapts toward
the workload it currently serves, in a demand-aware and online manner.
Self-adjusting networks are motivated, e.g., by distributed machine
learning applications whose traffic pattern features specific structure and
can hence be exploited and optimized for. Our vision of self-adjusting
networks is enabled by emerging optical technologies which allow us to
adjust the topology within milliseconds or even microseconds.

The vision of self-adjusting networks is similar to the vision of
self-adjusting datastructures such as splay trees, which self-optimize
themselves towards the key distribution. It is also similar to
information-theoretical concepts such as dynamic Huffman coding: codes
which adjust themselves over time.

The optimization problems underlying self-adjusting networks include topics
from online algorithms, graph spanner problems, expanders and information
theory to name a few. For a more concrete idea of the project, see also the
related papers below or our project website: https://self-adjusting.net/.

The position is at the University of Vienna, Austria, and comes with the
possibility to collaborate with the Ben Gurion University in Israel (Prof
Chen Avin), who is a project partner. If the candidate likes, it is also
possible to have a longer research stay in Israel, but this is not
mandatory.

To apply, please send your CV, motivation letter and reference letters to
me by email, or use the online portal at

Please do not hesitate to contact me if you have any questions.
