Alexander Mitsos Coordinates New Priority Program for Machine Learning in Process Engineering


The German Research Foundation (DFG) will establish 14 new priority programs.

This includes the program titled “Machine Learning in Process Engineering. Knowledge Meets Data: Interpretability, Extrapolation, Reliability, Trust” at RWTH Aachen University. Priority programs investigate the scientific foundations of current or emerging research areas. The priority program SSP 2331 “Machine Learning in Process Engineering” is coordinated by Professor Alexander Mitsos, director of the RWTH Chair of Process Systems Engineering and IRTG Principal Investigator.

IRTG Associated Fellow Florian Zwicke Passed His Doctoral Exam                  




On May 12, Florian Zwicke successfully defended his doctoral thesis. The title of the public lecture was „Adjoint Methods for the Efficient Solution of Inverse Problems“. The thesis was titled „Inverse Shape Design in Injection Molding Based on the Finite Element Method“. Both has been advised by Prof. Stefanie Elgeti.

Congratulations Florian!





IRTG Student Nicole Nellesen won Student Poster Competition Award




IRTG student Nicole Nellesen won the “2019 Student Poster Competition Award” in “Mathematical Models” at the USNCCM15. The name of her poster is “Certified Reduced Basis Methods in 3D-VAR Data Assimilation” and her advisor is Prof. Veroy-Grepl. The sponsor of the award is the journal CAMWA (Elsevier).

The US National Congress on Computational Mechanics (USNCCM15) took place in Austin, TX from July 28 – August 1, 2019. The Congress was organized by the USACM. Computational engineers and scientists worldwide from government, academia, and industry participated in the congress. It featured plenary and semi-plenary speakers, several honorary mini-symposia, more than seventy-five organized mini-symposia with keynote lectures and contributed talks and exhibits from various sponsors.

Congratulations Nicole!


IRTG Annual School



The Summer School took place in conjunction with the Annual Meeting. At the Summer School Principal Investigators, as well as guest lecturers, give short courses on pertinent topics. The aim is to amplify the common theme of the IRTG, give doctoral candidates a better orientation in the field of inverse problems, and identify common themes or methods within the area.

As part of the Summer School 2019 of the IRTG-2379 at Austin, which took place on July 25 and 26 2019, Prof. Thomas J.R. Hughes gave a special talk on “My 50+ Years in the Finite Element Method”. On July 25, Prof. Karen Veroy-Grepl gave a short course on “Model Order Reduction: Theory and Applications”. On Friday, July 26, Prof. Robert van de Geijn, Prof. Maggie Myers and Devangi Parikh gave a short course on “Optimizing Matrix Libraries”.


IRTG Annual Workshop



For the first time since the IRTG-2379 started in last year October, the Annual Meeting took place at our partner University, The University of Texas at Austin. The Annual Meeting takes place alternately in Aachen and Austin. The Annual Workshop and the Annual Summer School form the Annual Meeting.

The Annual Workshop is meant for the IRTG doctoral researchers and the associated doctoral researchers to come together, present their work to the PI’s and peers, obtain feedback in a collegial environment, and become better acquainted with other research themes.

This year the Annual Workshop of the IRTG-2379 took place on July 23 and July 24, 2019. On Tuesday Prof. Tinsley Oden hold the keynote talk. After his opending talk there were several talks by the IRTG fellows about their projects. This proposal is meant to give a thorough overview of the state of the art, and indicate the relevance of the proposed research in the context of the existing body of work. The workshop ended with a poster presentation.

CDLS – Prof. Karen Willcox, Ph.D. – Projection-based Model Reduction: Formulations for Scientific Machine Learning

Twice a year, the AICES fellows organize the prestigious Charlemagne Lecture, whose objective is to invite persons, who have achieved impressive accomplishments throughout their career and, in this sense, to get inspired by their scientific achievements.
As the 17th speaker, the AICES fellows invited Prof. Karen Willcox, Ph.D., Director of the Oden Institute for Computational Engineering and Sciences, Professor of Aerospace Engineering and Engineering Mechanics at Oden Institute for Computational Engineering and Sciences, the University of Texas at Austin, USA.
Professor Willcox gave a talk on „Projection-based Model Reduction: Formulations for Scientific Machine Learning“ on April 30, 2019 at 4:30 pm.
We were very pleased about her visit and we will be honoured to welcome Prof. Karen Willcox Ph.D. any time again.

German Research Foundation Approves Establishment of Three Research Training Groups at RWTH ,05/2018

The German Research Foundation, DFG, has approved three proposals for research training groups from RWTH Aachen. In October, the University will launch the groups to educate and promote highly qualified doctoral candidates. The name of the international research training group is “Modern Inverse Problems: From Geometry and Data to Models and Applications“. The international research training group consists of researchers from the Aachen Institute of Advanced Study in Computational Engineering Science (AICES) and the Institute for Computational Engineering and Sciences (ICES) at the University of Texas at Austin. Special emphasis will be placed on inverse problems, focusing in particular on the interaction between geometry, data, models, and applications. Eleven RWTH professors are involved in the group, whose spokesperson is Professor Marek Behr, Chair of Computational Analysis of Technical Systems, CATS.

We are looking forward to a successful IRTG and a great cooperation between RWTH Aachen University and the University of Texas at Austin.
