The 7th Annual

Scientific Software Days Conference

Austin, Texas

February 25–26, 2016


Scientific Software Days (SSD) is a successful regional conference that has been held for seven years running at the University of Texas, Austin. This year we are seeking to expand the impact of the conference to a national scale. The target audience are users and developers of scientific software, and the goals of the conference are two fold:

  1. Share best practices among scientific software communities.
  2. Share the latest tools and technology relevant to scientific software.

Past keynotes speakers include Greg Wilson (2008), Victoria Stodden (2009), Steve Easterbrook (2010), Fernando Perez (2011), Aleksandra Pawlik and Will Schroeder (2012), and Neil Chue Hong (2013).

Conference registration is done through Eventbrite. Click the 'Register' button and you can then select what type of registration (student vs. non-student) to purchase.

  • If you register as a student, please remember to bring valid student ID with you to the event.
  • Refunds will be allowed up until two weeks before the event.
  • To present proof of your registration purchase at the conference, please either print out your ticket or use the Eventbrite mobile app to present your ticket.

Poster Session

A poster session will be held on Thursday, February 25, where participants can share their work related to scientific software. Posters may present specific scientific libraries, packages, frameworks, etc.; they may also present work addressing common issues in scientific software development, such as reproducibility, verification, profiling, portability, performance, etc.

If you are interested in participating, please email the conference organizers (, and include the names of all authors, the title, and an abstract (max. 75 words) for your poster. Poster presenters may also prepare 2-3 slides for a lightning talk before the poster session, if they choose.
