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 to more complicated coefficient models and other algorithms.


Porträt Simon RuetzSimon Ruetz
Newest PhD student.

Has an MSc in financial math from ETH Zurich and joined the project as PhD student in May 2019. He is working on dictionary learning with non-homogeneous coefficient distributions, with the ultimate goal of 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.


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.




Porträt Achilles TzioufasAchillefs Tzioufas

Has a BSc in statistics from Athens University of Economics and Business and a PhD in Actuarial Mathematics and Statistics from Heriot-Watt University. Joined the project from May 2019 to July 2020 to help with the not so basic probability questions. He was investigating percolation and spin systems in Markov processes.
