Algebraic Combinatorics and Category Theory in Topological Data Analysis

Dear all,

We are organizing a single day online workshop, titled Algebraic Combinatorics and Category Theory in Topological Data Analysis. This will take place on Saturday, March 12, 2022. This workshop is a substitute for a special session in the cancelled AMS Spring Southeastern Sectional Meeting. The webpage is

We plan to start at 8:50am Eastern Time (= 2:50pm Central European Time). Zoom coordinates and a detailed timetable will be released on the webpage several days beforehand. We hope to meet many friends and colleagues on March 12!

Best wishes,

Woojin Kim, Alex McCleary, Facundo Mémoli, and Amit Patel.

AATRN poster session, Jan 25

Dear all,

We (Henry, Antonio, Hanka, Teresa) are organizing the second AATRN (Applied Algebraic Topology Research Network) poster session via Zoom, with the intention of giving a platform to younger members of our community to showcase their work, as well as a place for everyone to present their most recent research results. Topics of interest will span the full range of applied and computational topology.

The webpage for the poster sessions is at

The poster session will take place on Tuesday, January 25, 2022, at 11am Eastern Time = 5pm Central European Time. To submit a poster title and abstract, please fill out the registration form at

by January 15th, 2022.

Zoom coordinates and the website with the program will be sent out to the AATRN email list several days beforehand.

Best wishes,

Tenure-track Assistant Professor in Topology at the University of Tennessee

The Department of Mathematics at the University of Tennessee (Knoxville) is hiring  an assistant professor in Topology; while the search is broadly in the area, the department is particularly interested in hiring a researcher in applied topology. Please apply by November 1 at Note the instructions about the cover letter; this letter will help the committee gauge the candidate’s level of interest in the position.

The department is also having an area-open search for three postdocs (, and would be particularly interested in hiring a postdoc who could interact with the incoming assistant professor in Topology. In fact, choice of one of the postdocs could be a point of negotiation with the incoming assistant professor if time permits.

Join us in making Applied Topology tutorials!

Dear Colleagues,

Last spring, AATRN (Applied Algebraic Topology Research Network) and WinCompTop (Women in Computational Topology) hosted the inaugural tutorial-a-thon, where participants created ten-minute YouTube videos on subjects related to applied topology (broadly interpreted). Check out the Spring 2021 tutorial videos here. The event was such a great success that we will be hosting a second tutorial-a-thon this fall!

We will meet Thursday, October 28 at 11:30am Eastern time for a kick-off event, where participants will split into groups to meet in subsequent weeks to practice and record videos. In addition to creating useful content for the community, this event is also a great way to meet new mathematicians! We particularly encourage early career individuals to participate. Please see the webpage and fill out the interest form to receive more information. 

Best, the organizers: Henry Adams, Hana Dal Poz Kouřimská, Teresa Heiss, Sarah Percival, Lori Ziegelmeier

With thanks to AATRN and WinCompTop.

Postdoctoral position in Mathematics at Colorado State University

The Department of Mathematics at Colorado State University plans to hire approximately three postdocs to start in Fall, 2022. All research areas in the department are sought, and we (Henry Adams and Amit Patel) will be encouraging the department to consider hiring a talented candidate in applied topology, to be co-advised by both of us.

For more information, please see the advertisement on MathJobs:

Though the listed deadline is July 2022, we encourage folks to have their applications submitted before the end of November 2021, if possible.

Applied Topology in Bedlewo 2022

From Paweł Dłotko:

Dear All,
We would like to remind you about the third edition of Applied Topology in the Bedlewo Conference that will happen on 3-8 July 2022. 
Please visit our webpage:
This is a conference showcasing cutting edge as well classical aspects of applied topology — both inside and outside mathematics.

We have a strong desire to make this conference an in-person event, as we believe that human-to-human interaction and informal exchange of ideas is the key to a successful conference — something that cannot be replaced by an online meeting. There are a few reasons why we think that we can make this conference safe and enjoyable to our participants.
Firstly, Bedlewo Conference Centre has a vast hotel base, so we can accommodate our participants in single rooms. Lots of activities can be done in fresh air, and at present we are practising all possible options to serve meals in full social distance. Moreover, a new large
a lecture room for 150 persons and with direct screen transmission to other lectures had been constructed recently. This will allow us to keep a distance between participants.

Secondly, the time of the conference, which is the beginning of  July, coincides with a global minimum of a number of Covid infections. We hope to take advantage of those breaks between eventual  pandemic waves to have a successful conference.

Given the restrictions, the number of places is limited, therefore if you want to join us in Bedlewo, we strongly encourage you to register as soon as possible on our webpage. The Organizing Committee will inform you of an acceptance as soon as possible. Please note that some options in the registration form (online participation, booking of a hotel room do not apply to this conference and are there just because of a fixed registration form – please do not use them)

Please feel free to contact me if you have any questions,
Looking forward to see yon in Bedlewo,
Best wishes,
Pawel Dlotko
On Behalf of the Organizing Committee,
Paweł Dłotko, Wacław Marzantowicz, Justyna Signerska-Rynkowska

Invitation to the 2nd Workshop on Topological Methods in Data Analysis

From 4th to 6th of October the Second Workshop on Topological Methods in Data Analysis will take place within the cluster of excellence STRUCTURES at Heidelberg University. The three-day workshop includes introductions into the powerful data analysis machinery of persistent homology, extensive tutorials on the versatile GUDHI library, and in particular features invited colloquial talks by well-known experts in the field, aiming for a broader audience. In addition, participants will have the opportunity to give a short presentation on their own TDA-related work. The workshop will take place online only.

Please find more information including the detailed schedule on the corresponding webpage and the attached information sheet.

We are pleased to announce that registration for the workshop is now open until October 1st. Registration proceeds via filling out this form. Shortly in advance to the workshop we will send around respective Zoom links.

Feel free to share this invitation with interested colleagues.

We are looking forward to your participation.

Do not hesitate to contact us in the case of questions.
