Coven-Wood lectures at Wesleyan

Robert Ghrist will give the Coven-Wood Lectures at Wesleyan University this year ( They will take place on Wednesday 4/25 and Thursday 4/26. The abstracts are below.

“Homological Tools for Data” (Wednesday)

Abstract: The past fifteen years has witnessed a dramatic burst of applications of topological thinking and theorems in the applied sciences, ranging from statistics to sensor networks, neuroscience, and more, to be surveyed here. Several challenges remain, including: (1) how to compute topological quantities efficiently; (2) how to extend the set of current applications and methods; and, perhaps most importantly, (3) how to educate end-users in the meaning and proper use of homological tools.
This talk will demonstrate why homology is one of the most exciting new tools in applied mathematics.


“New Uses for Sheaf Theory” (Thursday)

Abstract: As ideas from algebraic topology diffuse over into applied domains, we see a recapitulation of the subject’s genesis. First, the use of Betti numbers; next, functoriality (cf. persistent homology); then, categorification (current work on stability and interleaving in topological data analysis).
What next?  This talk will argue that sheaves and sheaf theory are a good candidate for the next toolbox for applied data science. The talk will give a gentle overview of this (intimidating) subject and provide details of a new class of sheaves useful in inference problems associated with sensor networks.

TDA and Persistent Homology: summer school in Trento (Italy)

Topological Data Analysis and Persistent Homology – Second Announcement

A school devoted to Topological Data Analysis and Persistent Homology

will take place from Monday, June 11 to Friday June 15, 2018,

at the Hotel Bellavista in Levico Terme (Trento, Italy),

in the framework of the scientific activity of CIRM-FBK (

Topological Data Analysis (TDA) is a new research area that has recently attracted

the attention of various scientific communities, both from pure and applied mathematics.

The aim of this school is to provide a gentle introduction to TDA, starting from scratch,

providing concrete applications and getting to the state of the art. Lectures are given

by some of the most recognized specialists in this field and are addressed to a broad audience,

mixing PhD students and young Post-Docs with more experienced researchers from

different disciplines, among which Algebraic Topology and Algebraic Geometry.

The final program consists of three mini-courses delivered by John Harer

(Duke University), Steve Oudot (INRIA Saclay) and Christopher J. Tralie

(Duke University).

For details we refer to the updated official webpage of the school, published at the link

Some funds to cover living expenses for young participants are available.

The deadline for registration and application for financial support is April 30, 2018.

Looking forward to seeing you in Levico,

The organizers

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!

TRIPODS Workshop: Theory and Foundations of TGDA

TGDA@OSU TRIPODS Center Workshop: Theory and Foundations of TGDA

will take place at the Ohio State University in Columbus OH, May 21-25, 2018.

For details on how to register, apply for travel support, and a list of speakers, please visit the workshop website:

The workshop will feature a range of invited talks on topological, computational, and statistical aspects of Data Analysis. We encourage anyone working in this field to attend the workshop, and to register by March 12, 2018.

One of our goals is to reach out to junior researchers who intend to work in this field, and we can offer financial support to a limited number of domestic PhD students and junior researchers who apply by March 12. 

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.

For more information or to apply, please contact me at
