ABCD-ReproNim Hackathon 2026

ABCD-ReproNim is pleased to announce a 4-day hackathon on January 20-23, 2026 in Hollywood, Florida. The ABCD-ReproNim Hackathon was designed to promote collaborative analyses of ABCD data using reproducible and responsible methods. ABCD-ReproNim aims to equip researchers with the tools to improve their data science and computational method repertoire. The ABCD-ReproNim Hackathon will allow attendees to have open time to work in interdisciplinary teams on projects that utilize computational techniques to solve problems of interest to the broader ABCD community.

Dates:	January 20-23, 2026
Who:	We are inviting researchers with interests in the ABCD Study to attend this event and contribute to ABCD data analysis projects. Collaborative analysis teams will include individuals with a range of skills, from novice trainees to expert data analysts. Students, postdoctoral fellows, staff, and faculty are all invited to apply.
Cost:	There is no charge for this event. Individuals interested in attending should submit an application. If selected, we will pay for your travel costs and make all of your travel arrangements. The hackathon includes onsite breakfast and lunch; a stipend will be provided for dinner.
Location:	Margaritaville Resort, Hollywood, Florida
Deadline:	Applications are due by December 1st, 2026
Note:	We follow the code of conduct of BrainHack Global.

Why Hack?

A hackathon is a collaborative event that focuses on the open sharing of ideas, models, code, and data. They bring together brain experts and enthusiasts from a variety of backgrounds to build relationships, learn from one another, and collaborate on projects related to the neurosciences.

We also encourage new programmers and students/scientists to participate in our hackathon this year. We pair experienced Hackers with new folks to help kickstart your growth as a neurohacker!

Learn

Learn about tools, techniques and datasets in neuroimaging research.

Be Social

Meet researchers from a variety of backgrounds. Share your knowledge.

Get Involved

Find exciting projects that you would like to contribute to.

Program & Schedule

This four day event will bring together local scientists and trainees in neuroimaging from institutions across the region. The program will include:

Open Hacking sessions in which attendees will work together on projects of their own design. Attendees are encouraged but not required to bring their own projects into the hackathon to work collaboratively with others. Project inspirations could stem from other projects proposed by attendees, ongoing work you're involved in, or new research areas that you've been waiting to have an opportunity to jump on!
Unconference & Tutorials to help you get up to speed with various programming languages and current practices in open-source and reproducible neuroimaging analysis.

Program Description

Introduction to Hacking: Hacking isn't just about code — it can mean creatively solving problems in analysis, experimental design, and more. This session welcomes all backgrounds and highlights how interdisciplinary collaboration fuels innovation.
Project Pitches: Attendees pitch ideas they’d like to explore, discuss technological or conceptual gaps, and begin forming collaborative teams around shared interests.
Coffee Break: Time to recharge and chat informally.
Review of ABCD Resources: A brief overview of helpful software, datasets, platforms, and tools. Topics may later become UnTutorial sessions based on attendee interest.
Group Discussion and Questions: Open Q&A to wrap up the morning and align goals.
UnTutorials and Hacking: Work time for those with a clear plan, or spontaneous tutorials chosen by attendee interest. Sessions happen only if enough participants express interest.
Free Hacking: Unstructured time to work on projects, get support, or extend tutorials.
Project Check In: Teams provide morning updates — progress, goals, or blockers.
Project Reports and Feedback: Final reports and reflections on project progress, outcomes, and ideas for future hackathons.

Project Pitches

Open hacking projects are a great forum for getting support on a technical issue from your own research program or starting a new collaborative project.
