Porträt Karin SchnassKarin Schnass
Source of the start project.

Has an MSc in math from the University of Vienna and a PhD in computer, communication and information sciences from EPFL. Despite these fancy degrees she neither believes in the axiom of choice nor can she fix computers.

Porträt Marie PaliMarie Christine Pali
PhD student and renaissance woman.

Has an MSc in math from the University of Innsbruck. Joined the project in November 2016 for an internship and 4 months later decided to go for the PhD with us. She is not only journeywoman for carpentry but also an expert for Navier Stokes equations. Currently she is developing her endurance and probability skills while working on extending recovery results for dictionary learning and sparse approximation to more complicated coefficient and noise models.


Porträt Simon RuetzSimon Ruetz
PhD student and tablet whisperer.

Has an MSc in financial math from ETH Zurich and joined the project as PhD student in May 2019. He is working on conditioning of random subdictionaries with an eye towards dictionary learning with non-homogeneous coefficient distributions. The ultimate goal is stabilising adaptive dictionary learning for image data and exploiting knowledge about the coefficient distribution for signal recovery - thus making deep learning obsolete - well you have to set high goals.


Porträt Elisabeth SchneckenreiterElisabeth Schneckenreiter
Newest PhD student.

Has an MSc in teaching math and chemistry from the University of Innsbruck. She joined the project as PhD student in November 2020, after we did everything humanly possible to discourage her and thus not keep her from saving our schools. They closed 2 weeks later.
She is working on the identification all the bad dictionaries that lead us astray, especially when not all atoms are used with equal probability. Then she will invent counter-measures and once everything is in place, we will put that chemistry degree to good use and do some image-processing for FISH-images in biology.


Former Members

Flavio TeixeiraFlavio Teixeira
Postdoc and computer expert.

Has MSc/PhD degrees in electrical engineering from the University of Brasilia and the University of Victoria. Joined the project in April 2016 to work on compressed dictionary learning and to remind Karin to water the plant. He actually knows how to program and volunteered to turn all our matlab hacks into proper C or Python toolboxes! Unfortunately the Canadian residence permit threatened to expire before we could take him up on the offer.

Porträt Michael SandbichlerMichael Sandbichler
Adopted PhD student and evil/math genius.

Has MSc degrees in math and physics and since June 2018 also a PhD degree in math from the University of Innsbruck. Joined the project right from the beginning until March'18 to work on analysis operator learning. Used to amaze with total lack of any programming style and the ability to understand and translate Karin's half sentences. He is now working as Vision Software Engineer (irony) at

Besi Austria GmbH.


Porträt Andreas KoflerAndreas Kofler
Our man in Berlin.

Has an MSc in math from the University of Innsbruck and joined the project for a 4-month PhD-trial in October 2015. Gave Michi and Karin the holy blackbox for using the computing cluster (all parts since confirmed necessary by Flavio and several calls from cluster maintenance), but then decided to get a real job. Once the real job turned surreal he went to Berlin, where he is now doing a PhD in CT/MRT imaging.




Achilles Tzioufas
Postdoc, May 2019 to July 2020.
