About Explorations

A warm welcome to the WCS Explorations, WCS’s sub-committee to help you with all things technical! We offer frequent workshops to hone your technical skills for classes and personal projects, interview preparation workshops to help you ace your next job interview, and project teams for a chance to work together in groups of about six people (including a project manager) and learn on-the-job skills. We also host the annual female and non-binary only hackathon, Code Ada, in October! If you have any questions, please don't hesitate to reach out to Darci Peoples or Melissa Chen.

[NEW!] Question Box

WCS is launching our own ask box where you can ask questions about any CS/non-CS related topics! In the upcoming weeks, we will invite special speakers to answer questions about cool topics like machine learning, research, etc. Just submit a question in this form and we’ll get back to you in a few days! We want this to be safe space, so if you choose to, you can remain anonymous. Go to our website to see past questions and answers or ask your own!

WCS Explorations Book Club

Alongside learning the technical skills that will help our members succeed, book club will be encouraging the developers of the future to consider the history and ethics of computer science. We're kicking off our pilot book club with Algorithms of Oppression by Safiya Noble. If you are interested in joining our weekly discussions, which will be taking place synchronously on Zoom every Monday at 5 PM CST and asynchronously on Slack, join the WCS Slack and hop in the #book-club channel. We will be posting the weekly reading schedule, holding asynchronous discussions, and making announcements there.

Project Teams

This year, WCS is hosting eight project teams working on a variety of projects with social good and engineering education applications. From adding new features to existing campus accessibility tools or creating a STEM trivia application, to crafting a racial microaggression detector or imagining new tools to help students stay productive during the pandemic, our project teams are set on taking on some of the greatest challenges posed to our community in 2021. Corporate sponsors: if you are interested in learning more about our student's work or participating in our midpoint or final presentations, please reach out to our corporate committee.

Code Ada

Code Ada is our annual all-female and non-binary hackathon, hosted by Explorations every October/November. For more information on how to get involved as an attendee, mentor, or corporate sponsor, please check out the Code Ada page.
