Khoury Teaching Workshop Series

I believe Artificial Intelligence is for Everyone. AI is making Computer Science more inclusive and creating new opportunities for innovation. So now we face an urgent need for faculty, staff, and students across the University to become AI-literate, to be familiar with AI’s potential and its current limitations while recognizing that advancements are happening at an accelerating pace. And we must explore ways to weave AI into a reimagined curriculum... Full opening remarks to workshop #1: AI in CS Education (03/26/2025)
Darwin saw in the diversity of finches beaks and tortoise shells the creativity of nature writ large: Individual organisms, struggling for their own survival, yet creating together a view of life full of grandeur. We know today that natural biological ecosystems are healthy, sustainable, resilient, and most able to adapt to environmental change when they are inherently biodiverse. Intellectual diversity is no less important in sustaining a vibrant classroom environment. Full opening remarks to workshop #2: CS for All: Creating an Inclusive Classroom (11/04/2025)
