ATMCS 8 Call for Papers

It is a great pleasure to announce the 8th event in a conference series on Algebraic Topology: Methods, Computation, and Science, which will be held at the Institute of Science and Technology Austria (IST Austria) just 30 minutes from Vienna, on June 25–29, 2018. The conference is organized by IST Austria and the local organizers are Prof. Herbert Edelsbrunner and Prof. Uli Wagner from the Algorithms, Geometry and Topology and Discrete and Computational Geometry and Topology research groups, respectively.

The ATMCS conference series is the main event in the flourishing area that connects algebraic topology with computer science and the natural sciences. It happens every two years and attracts the top established researchers as well as the best young talent in the field. In particular, there is a direct connection to the data science stream, and applications discussed at the meeting will touch research in biology and neuroscience, among others fields.

A key goal of the conference series is the further development of topological techniques for use in applications and the creation of new areas of applications in the subject. This conference series maintains a strong tradition of bringing together leading established researcher and young scientists in this emerging discipline, providing an opportunity for the exchange of experience and the development of new research ideas.

ATMCS8 invites submissions for contributed short talks (30 minutes) or research posters. For more information see

The website will be updated with current information, so please be sure to check back as the conference date approaches. Don't hesitate to write to if you have any questions.

We look forward to welcoming you at IST!

A week long summer school will precede the workshop, please encourage young researchers to apply:

Postdoc position in Aberdeen

Ran Levi writes:

The Institute of Mathematics in Aberdeen will soon be advertising a postdoctoral position funded by an EPSRC grant obtained by myself. The project which is entitled “Topological Analysis of Neural Systems” already employs two postdoctoral fellows and is expected to grow further. It is a collaborative and interdisciplinary project by its very nature, and aims to apply the powerful tools of algebraic topology to questions in neuroscience. A summary of the project can be found on the EPSRC website.  A large part of the project will be carried out in collaboration with the Blue Brain Project at EPFL, led by neuroscientist Henry Markram, and the Laboratory for Topology and Neuroscience led by Kathryn Hess. 

The post in Aberdeen is funded for 18 months, and will include a generous travel and equipment budget. Work on this project will involve both theoretical and applied topology. Start date is 1st September 2018, but a different start date may be negotiated. 

The position is intended for a person holding a PhD in algebraic topology, applied and computational topology or computer science with a strong interest in studying and applying theoretical and computational tools of algebraic topology to neuroscience, and other relevant subjects. Experience in computations and/or applied algebraic topology would be an advantage. Basic training in neuroscience will be available if necessary.

The post should be advertised in 2-3 weeks. Another announcement will be posted to AlgTop. In the meanwhile informal inquiries are very welcome. Please email

Postdoc at Air Force Research Laboratory

Postdoc position at Air Force Research Laboratory (AFRL)

I am looking to hire a postdoc for a project that is focused on studying categories of (various classes of) dynamical systems. The project has dual, interconnected purposes: (i) developing categorical models of coupled, physically realizable nonlinear systems and their properties; as well as (ii) exploring the internal structure of these categories with an eye toward type theoretic connections.

Candidates must be U.S. citizens, preferably with a background in applied category theory, type theory or related fields. The position is in Dayton, Ohio, USA, for one year with two additional years possible; the starting date is flexible.

PhD position at Tulane in TDA for Digital Pathology

Carola Wenk writes
I have an opening for a PhD position in the use of topological descriptors and HPC methods for digital pathology, see below.

A PhD research assistantship in visualization and computational topology of biomedical data is available in the Department of Computer Science at Tulane University under the supervision of Brian Summa and Carola Wenk, part of the NSF-funded project "Quantifying Morphologic Phenotypes in Prostate Cancer - Developing Topological Descriptors for Machine Learning Algorithms". See here for more information on the project:
This is an interdisciplinary project including faculty and students from Tulane University and Montana State University in the areas of Mathematics, Computer Science, Biomedical Engineering, and Pathology.

The focus of this PhD research assistantship is on the visualization and high-performance computing aspects of topological descriptors computed on gigapixel image data. This research assistantship is for three years of the typically 5-year PhD program in Computer Science, starting in Fall 2018.

Department information

KTH Computer Science and Communication (CSC) announces PhD positions in Machine Learning at the department of Robotics, Perception and Learning (RPL)

Job description

The scientific work will be conducted along either of the following research directions:

1) Geometric and Topological Methods for Machine Learning with applications to Robotics

Topological Data Analysis is a recently emerging sub-branch of machine learning that enables inference about the global structure of datasets based on rigorous mathematical theory with origins in Algebraic Topology. The research under this theme will focus on developing new geometric and topological techniques for machine learning with a focus on potential application areas in robotics. Possible applications of Geometric and Topological Data Analysis in Robotics include reasoning about robot configuration spaces and free space. This could include development of approaches to autonomously detect unsafe configurations in a self-driving car scenario and to understand how compact components of the free space can be utilized to enable new types of robot manipulation interactions by means of the concept of "Caging". A second potential sub-thread is to investigate how Topological Data Analysis may be of use to analyze representations of data determined by Deep Learning Algorithms. The research will be supervised by Florian Pokorny, Assistant Professor at RPL.

2) Data-driven scene understanding and control in Human-Robot collaborative settings

Future robotic applications are believed to a greater extent include collaboration with humans, humans that do not necessarily have a technical background. Interaction between human and robot thus need to be in a manner that the human finds natural. A collaborative robot should adapt to changes in the environment and tasks that are placed on it. It needs to be in constant learning mode and gradually adjust its behaviours given feedback from both its sensory system and the human collaborator. Research under this theme will focus on a combination of deep learning for scene understanding and generative action modelling, with reinforcement learning applied for control. Emphasis will be placed on methods with which a human can teach a robot the best way of solving a particular task, either through demonstration or by physically guiding the robot. The research will be supervised by Mårten Björkman, Associate Professor at RPL.

This is a four-year time-limited position that can be extended up to a year with the inclusion of a maximum of 20% departmental duties, usually teaching. In order to be employed, you must apply and be accepted as a doctoral student at KTH.
