OwlHacks Hackathon

Dr. Stephen MacNeil has been the faculty director of OwlHacks since 2021. While offered once before the pandemic, it did not survive the shift to online. The Temple HCI Lab revived the event and has grown it from a small initial success into one of the largest hackathons in the Philadelphia region.
