Georgia Topology Conference

The topology group at the University of Georgia is organizing a conference on topological persistence and related topics in applied topology in Athens, Georgia, from June 1-5, 2020. This will be an installment in a long-running (since 1961, see here for webpages from previous years) annual topology conference series, which is maybe best known for the large general conferences that are held in years congruent to 1 mod 8; however in years such as this one the conference is smaller and focuses on a more specialized theme, typically with about 16 one-hour talks by a mix of junior and senior researchers and plenty of time built into the schedule for informal interaction.  

The webpage for the conference is now up, at  The conference will be supported by NSF. In particular there is funding available for junior participants.

TDA Postdoc, Cornell

The Greater Data Science Cooperative Institute (GDSC), jointly established by Cornell University (CU) and the University of Rochester (UR) as part of the NSF funded HDR TRIPODS program, seeks exceptional candidates for postdoctoral research positions at Cornell (note: UR has a simultaneous and coordinated, but separate search). Appointments are renewable up to a total period of three years. The target start date is August 1, 2020, but positions may be filled immediately.

GDSC is based on two founding tenets: that enduring advances in data science require combining techniques and viewpoints across electrical engineering, mathematics, statistics, and theoretical computer science; and, that data-science research must be grounded in an application domain. Cross-disciplinary research directions include: (i) Topological Data Analysis; (ii) Data Representation; (iii) Network & Graph Learning; (iv) Decisions, Control & Dynamic Learning; and, (v) Diverse & Complex Modalities. GDSC specifically aims to consider applications in medicine and healthcare, a major strength of CU and UR, and one for which advances in data science can have a direct, positive impact on society. Applicants should have completed their PhD in a discipline listed above (or related) by the time of their appointment. Some background or interest in biomedicine and/or healthcare would be an advantage.

Cornell appointed postdocs will be mentored by at least two GDSC members, including one from the Cornell GDSC leadership team: David S. Matteson, Aaron Wagner, Qing Zhao, David Bindel and Gennady Samorodnitsky. The Rochester GDSC leadership team includes Mujdat Cetin, Daniel Gildea, Tong Tong Wu, Alex Iosevich and Daniel Stefankovic; and GDSC includes 17 additional founding senior personnel across CU and UR (see: for more information).

Any questions about the Cornell positions can be sent to David S. Matteson (; and please contact Mujdat Cetin ( for questions about the UR positions. All applicants must submit a cover letter, a curriculum vitae including a list of publications, research and teaching statements, and arrange to have two reference letters submitted electronically. Up to two relevant research publications may also be submitted. Application materials must be submitted at:

Evaluation of applicants will begin February 15, 2020 and continue until the position is filled.

Air Force Research Lab: Summer of TDA Internship

This summer in Dayton OH, our group at AFRL is hosting a summer of TDA 10 week internship program. During these 10 weeks interns will work on DOD relevant data sets exploring the use of TDA to develop explainable artificial intelligence systems as well as user interface visualization dashbroads.  This internship is with the Air Force Research Lab 711th Human Performance Wing, led by Dr. Ryan Kramer and is administered through KBR Inc., a DOD contracting and support company.  The KBR link to the job description and link to apply is below.


The WinCompTop@ATMCS event, organized by Erin Chambers, Ellen Gasparovic, and Yusu Wang, will be held June 6-7 at The Ohio State University.  Any member of the community (man or women) is welcome and encouraged to join us for this meeting.  In addition to talks by participants from the prior WinCompTop workshops and members of the community, there will also be a panel discussion, a dinner or social event, and open time for working groups to meet (or start new projects).  Funding is available to help with travel, particularly for junior participants.  

If you were a participant of one of the first two workshops and would be interested in talking about your group’s project or follow-up work, please get in touch with an organizer! 

After scheduling these talks, we plan to add additional talk slots for members of the community, but we hoped to first showcase some of the fantastic research that came out of WinCompTop 1 and 2.

Stay tuned for funding details and a program soon, and we hope to see many of you there!

Computational Geometry: Media Exposition — First Announcement

Please see the call below. Notice that this media track has expanded its definition to have a wider scope this year. We welcome your submissions!

Here is the corresponding webpage:

Computational Geometry: Media Exposition — First Announcement

Media, Visualizations, and Geometric Art are sought for the 29th International Computational Geometry Media Exposition (CG:ME), which will take place as part of Computational Geometry Week 2020, encompassing the 35th International Symposium on Computational Geometry. Submissions showcase creative approaches to illustrate research and/or support education in computational geometry. 


All deadlines are 23:59 anywhere on earth.

  • February 21, 2020 Abstract and media portfolio submissions due
  • March 8, 2020 Notification of acceptance/rejection
  • March 30, 2020 Final version of abstract and portfolio
  • June 23-26, 2020 Computational Geometry Week


  • The submission should be related to computational geometry, broadly interpreted, but is otherwise unrestricted: for example, it can illustrate a (new or existing) concept, technique or algorithm from computational geometry, it can explain an application of computational geometry, it can be meant for educational purposes or for entertainment purposes, and so on. 
  • The form of media is broad, including algorithm animations, interactive software and games, scientific artwork, sculptures, paintings, and virtual reality demonstrations. While videos are welcome, they are no longer required as in previous years.


A submission consists of two parts: a portfolio and a paper.

  • Submit a portfolio of the work, such as images, video, link to interactive apps, etc.  The submission should still be “displayable” during CGweek, and the authors should specify in their submission how the piece will be displayed. For example, if it is about a geometry-inspired sculpture, then one can bring the sculpture itself, or submit a video about this sculpture, its story and its connection to computational geometry. Note that if your work is a video, then the portfolio and the work are in fact identical.
  • Submit a paper which details the portfolio and where applicable, the techniques used in the implementation. The paper should explain the connection of the submission to computational geometry, broadly interpreted.  
  • Acceptance is based on both the submitted portfolio and the accompanying paper.

Technical Details

  • Portfolio submissions are limited to 100 MB. Authors are free to post higher quality versions on their own web sites, and we will include links in the electronic proceedings to their version, in addition to the official version (<100 MB) archived on
  • Videos should be 720p or better, using H.264, where the embedded audio stream should be AAC of at least 128kBit/s.
  • The paper must be formatted according to the guidelines for the conference proceedings using the LIPIcs format, and not exceed 100 lines, excluding front matter and references.  The number of images in the paper should also be kept reasonable. Typesetting instructions and the .cls style file are available on the CG website:


  • The Work will be on display at a gallery during Computational Geometry Week.  
  • The authors will have a session devoted to giving a short talk on their work at the Symposium on Computational Geometry.
