Postdoc in TDA at EPFL

The Laboratory for Topology and Neuroscience (EPFL) and L2F—Learn to Forecast (EPFL Innovation Park) invite applications for two postdoctoral positions in topological data analysis and machine learning, funded by the project “Topological Warning Signals for Critical System Transitions” supported by Innosuisse (Swiss Innovation Agency).

The aim of this project is to develop original predictive methods, combining advances in topological data analysis with machine learning research. The first goal of the project, inspired by critical phase transitions, is to define a new type of early warning signal using applied topology, in order to better anticipate sudden changes of regime such as financial crashes, earthquakes, or epileptic attacks. The second goal concerns the creation of new local features by analyzing the topology of datasets, in order to generalize current topological data analysis techniques to enhance the performance of machine learning models. 

L2F is a research-driven company that offers mathematically sophisticated machine learning solutions to corporate and institutional clients. L2F’s researchers, who won the 2017 NYC Taxi Challenge on Kaggle, are motivated by the desire to understand the fundamental laws of machine learning, in terms of its underlying mathematical theory. L2F is one of the fastest growing Swiss companies, with already 30 employees after one year of existence, and provides an exciting environment for multi-disciplinary researchers.

The appointed candidates will be based at L2F on the EPFL Innovation Park and engage in state-of-the-art research, in collaboration with the Laboratory for Topology and Neuroscience.

Candidates should hold a PhD in one of the following areas: algebraic topology, theoretical physics, or machine learning. Please send your cover letter, CV, and publication list to Kathryn Hess at  and Maxime Gabella at, to whom you should arrange for three letters of reference to be sent as well.

Starting date: March 1, 2019, or as soon as possible thereafter.

Duration: 18 months.

Application deadline: January 1, 2019.

Applied Mathematical Modeling with Topological Techniques, ICERM, August 5-9, 2019

We are happy to announce an ICERM topical workshop on “Applied Mathematical Modeling with Topological Techniques”, August 5-9, 2019. Please see our webpage

Mathematical modelers face a variety of challenges, including summarizing large data sets to understand and explore a system of interest, inferring the model parameters most accurate for describing a given data set, and assessing the goodness-of-fit between data sets. Computational topology provides a lens through which these challenges may be addressed. At the same time, just as topological techniques provide opportunities for modelers, the challenges that modelers face give rise to opportunities for applied topologists. For instance, topologists may develop techniques that make model predictions based on the topology of experimental or simulation data, that analyze time-varying data, or that turn model outputs into formats suitable for machine learning.

This workshop brings together the applied mathematical modeling and applied topology communities, aiming to give modelers exposure to topological techniques still not commonly used in their community, and to give topologists exposure to modeling challenges that might stimulate the development of new techniques.

The workshop will include tutorial sessions on modeling and on applied topology, during which participants will learn by doing hands-on computational exercises. Because the broad goal of this workshop is to encourage collaboration between members of the applied modeling and topology communities, a significant portion of the week will be devoted to participants initiating research on problems proposed by the organizers. The research problems will afford the potential for continued collaboration beyond the workshop.

PhD positions at KTH Royal Institute of Technology (Stockholm, Sweden)

There are several PhD positions available in Artificial Intelligence at KTH Royal Institute of Technology in Stockholm.

Deadline: September 30th 2018

Detailed information:

Further information regarding project B):

Project B) may in particular be of interest also to students interested in Computational Topology/Geometry and Machine Learning as there are intriguing connections between e.g. computational geometry and recent machine learning approaches such as deep convolutional neural networks.

Data-Driven Foundations for Robust Deformable Object Manipulation

The project's goals are to develop new paradigms for machine learning under constraints imposed by physics. This is a key challenge with current approaches such as "Deep Learning" which often perform well empirically, but have to date few mathematical guarantees.

The student will in particular investigate how to combine approaches to rigorous mathematical modeling of deformable objects such as plastics and metal sheets with recent advances in machine learning for state estimation and prediction. The project will be conducted in collaboration also with Chalmers University where real-world experiments with industrial robots will be performed which will provide a possibility for validation of hypotheses and to test the applicability of the developed methods to controlling a robot's actions in deformable object manipulation tasks.

New ideas coming from geometry and topology, persistent homology and sheaf cohomology, etc may find application in developing new algorithms in this area and there is interest in candidates with a wide variety of backgrounds, including candidates with strong knowledge of computational geometry, algebraic geometry, topology, differential geometry, probability theory, etc.
