Postdoc, TDA for NLP, Düsseldorf

I am advertising a postdoc position at the intersection of topological data analysis, natural language processing and machine learning.

duration: 3 years
starting date: 1 October 2021
location: Heinrich Heine University Düsseldorf, Germany

Reflecting its interdisciplinary nature, the position is associated both with my group (Topology and Geometry) and with the research group of Prof. Milica Gasic (Dialogue Systems and Machine Learning). Prior experience in one or more of the named areas would be beneficial, but we are willing to consider outstanding candidates from other areas of mathematics.

The position will be paid at the TV-L E13 scale (see for more information). It comes with moderate teaching duties (2 times 90 minutes per week during teaching periods), which could be arranged to be of direct relevance for the intended research. Working knowledge of German would be beneficial but is not essential.

Applications and enquiries should be directed to by 30 August.

CfP: Applications of Topological Data Analysis to Big Data

***** Call for Papers: Workshop on Applications of Topological Data Analysis to Big Data at IEEE BigData 2021 *****

Topological Data Analysis (TDA) is a growing area of research that focuses on studying the “shape” of data. Tools (such as persistent homology) from TDA have been successful in many application areas, including signal processing, computer vision, dynamical systems, and geospatial systems. This workshop will be a venue for researchers and practitioners of TDA to present innovative, state-of-the-art topological methods and novel applications of topological tools to big data.In this workshop, we invite submissions on recent applications of topological data analysis, with a focus on larger datasets. Topics include but are not limited to:

  • TDA applications to graphs, hypergraphs and networks
  • TDA applications in natural language processing
  • TDA applications to image and video analysis
  • TDA applications in dynamical systems and signal processing
  • Topological approaches to spatial and social systems
  • Topological approaches to machine learning

TDA Postdoc in Aalborg, Denmark

What we offer:
We offer a postdoc position within the Department of Mathematical Sciences as part of the project “Deciphering Nanoporosity of Amorphous Materials using Topological Data Analysis”. The selected candidate will be conducting research supervised by Lisbeth Fajstrup and Christophe A.N. Biscio and in collaboration with the Department of Chemistry and Bioscience to find new topological descriptors of porosity.
The selected candidate will visit Lawrence Berkeley National Laboratory, USA for 4 months to collaborate with Staff Scientist Dmitriy Morozov.

What we request:
The selected candidate will hold a PhD in Mathematics or a related field and will have promising research results within Topological Data Analysis, Computational Topology or related subjects.
The project to which the postdoc will contribute involves developing the theory of non-monotone and multidimensional persistence to describe variations of the free volume and in particular tunnels in amorphous materials and implementation of such insight as a tool. This will require a strong background in Topological Data Analysis either theoretical or computational.

You may obtain further professional information from Associate Professor Christophe Biscio, phone: +45 9940 8925, e-mail: or Head of Department Søren Højsgaard, phone: +45 9940 8801, e-mail:

Qualification requirements: 

Appointment as Postdoc presupposes scientific qualifications at PhD–level or similar scientific qualifications. The research potential of each applicant will be emphasized in the overall assessment. Appointment as a Postdoc cannot exceed a period of four years in total at Aalborg University.

Geometry and Topology meet Data Analysis and Machine Learning

We would like to draw your attention to the “Second Graduate Student Conference: Geometry and Topology meet Data Analysis and Machine Learning (GTDAML2021)” to be held online July 30 – August 1, 2021. This is the second edition of the conference that was first held at The Ohio State University in 2019.
The goal of the conference is to bring together graduate students to share their work, interests, and presence in the flourishing research landscape connecting applications of Geometry and Topology to Data Analysis and Machine Learning. We aim to enhance discussion and collaboration via poster sessions, short presentations, and discussion panels.
The program will include a special lecture by Professor Deanna Needell from the Department of Mathematics at UCLA. In addition, we will have a discussion panel on industry and research. Some of our confirmed panelists include: Professor Lorin Crawford (Microsoft Research and Brown University), Professor Marco Cuturi (Google Brain and CREST – ENSAEInstitut Polytechnique de Paris), and Jesse Zhang (PhD Stanford, Co-Founder at Beacons).
Students may apply to give a 20 minute talk (through Zoom) or a poster presentation (through Talks and posters do not have to be about the participants’ own research, and expository talks are also very welcome. Students are encouraged to apply to give a talk, but if a talk cannot be scheduled due to time limitations, students are invited to present a poster instead. We are expecting to schedule around 20 talks in total. Registration details can be found at The deadline for applying to give a talk is June 7.
