Univ.Prof. Dr. Ansgar Jüngel receives an ERC Advanced Grant

Ansgar Jüngel, Professor of Analysis of Nonlinear PDEs and Head of the Research Unit of Analysis at the Institute of Analysis and Scientific Computing, won a prestigious ERC Advanced Grant for his project "Emerging network structures and neuromorphic applications". Last year, more than 2600 applicants submitted their proposals for an Advanced Grant of the European Research Council in all fields of research, but only 209 scientists all over Europe have been selected.

The project of Ansgar Jüngel is concerned with network structures appearing in, for instance, biological tissues, neuron systems, and nanoelectronic devices. These structures are inspiring for novel neuromorphic computer architectures, which emulate the functions of synapses and neurons. A key aspect of the project is to understand the morphology of neurons and circuits with the aim to develop novel low-power and high-density computer networks and to overcome physical scaling limits that heavily restrict the progress of nanoelectronics.

Jüngel's project focuses on the interplay of emerging structures in biological neuron systems and electronic circuit models. The objectives are

  • to explore the mathematical structure of the modeling equations, which are systems of nonlinear partial differential equations (PDEs),
  • to understand the coupling of the different types of equations (partially diffusive, stochastic, algebraic), and
  • to discretize these equations numerically using efficient and accurate algorithms.
The project is supposed to culminate in the simulation of small bio-inspired neuromorphic circuits, where memristor devices model the behavior of synapses or ion channels and mimic neuronal connectivity.

The project lies at the interface between biology, physics, and mathematics, with an outlook to artificial intelligence. Although being a mathematics-oriented project, Jüngel intends to cooperate with researchers from biology and physics and to strengthen his collaboration with colleagues from the Institute for Microelectronics at TU Wien.

Ansgar Jüngel received his PhD at TU Berlin in 1994. After stays at the University of Rostock (Germany) and the University of Nice (France), be became an associate professor at the University of Konstanz (Germany) in 1999 and a full professor at the University of Mainz (Germany) in 2002, before he moved to the TU Wien in 2006. He is the speaker of the FWF-funded doctoral school Dissipation and dispersion in nonlinear PDEs and a vice-speaker of the doctoral school Vienna School of Mathematics. He received the Gerhard-Hess Award of the German Science Foundation (DFG) in 1999 and the Tsung-Ming Tu Award of the National Science Council of Taiwan in 2011.

The Institute of Analysis and Scientific Computing congratulates Ansgar on this prestigious award. We looking forward to the novel mathematical developments at the interfaces to biology and physics.
