8:30 am - 4:30 pm

Instructors: Mark Meysenburg, Erin Doyle

Helpers: Tessa Durham Brooks, Adam Erk

General Information

The Digital Imaging and Vision Applications in Science (DIVAS) project is a collaborative venture between faculty at Doane University and St. Edward's University in Austin, Texas. The project addresses workforce challenges in science, technology, engineering, and mathematics (STEM) by creating a pedagogical and programmatic "onramp" that empowers natural science majors to engage in authentic computational problems as members of skilled, professional teams. Our interventions provide stimulating experiences for students, and aim to improve learning outcomes, and increase student retention and graduate rates in STEM fields. This project follows feedback from a previous NSF-funded planning grant (NSF ACI#1216869) that sought to determine the cyberinfrastructure needs for efficient phenomics research.

Who: The course is aimed at graduate students and other researchers. All attendees are expected to have an introductory knowledge of the Python programming language.
If you do not have previous experience with Python, it is recommend that you attend the Introduction to Python workshop being held the week before on January 3rd and 4th.

Where: Jackie Gaughan Multicutural Center - Unity Room, 1505 S Street, 1505 S St, Lincoln, NE 68508. Get directions with OpenStreetMap or Google Maps.

When: January 7-9, 2019. Add to your Google Calendar.

Cost: $60 / $30 for students


Requirements: Participants must bring a laptop with a Mac, Linux, or Windows operating system (not a tablet, Chromebook, etc.) that they have administrative privileges on. They should have a few specific software packages installed (listed below). They are also required to abide by Software Carpentry's Code of Conduct.

Accessibility: We are committed to making this workshop accessible to everybody. The workshop organizers have checked that:

Materials will be provided in advance of the workshop and large-print handouts are available if needed by notifying the organizers in advance. If we can help making learning easier for you (e.g. sign-language interpreters, lactation facilities) please get in touch (using contact details below) and we will attempt to provide them.

Contact: Please email hcc-support@unl.edu for more information.
