Cassie's approach to AI interface design proceeds from her early recognition of the epochal potential of Large Language Models: when the Transformer paper was published in 2017 in the midst of her MFA studies in Digital Language Arts at Brown University, she became convinced that AI would fundamentally reshape human-computer interaction, and committed to designing for this future. This insight has informed her work time and again over the past seven years, positioning her at the forefront of compositional AI interaction design.

Her recent research at the Royal College of Art resulted in Field, a paradigm, prototype, and platform for directing agentic ensembles under the sign of “redefining the universal interface layer.” This work pushes beyond conventional chat-based AI interactions, extrapolating systems in which users can fluidly compose and orchestrate AI agents through gathering as a creative medium. This year, she is building Threshold, a beautiful software tool that leverages Apple's Foundation Models frameworks to cultivate rich local context, demonstrating how AI can escalate rather than replace human agency toward altogether new forms of creativity.

Cassie's proficiency with SwiftUI and growing expertise with Swift enable her to create functional prototypes that bridge systemic design to implementation. Moreover, her extensive experience with Sketch, Figma, Rive, Keynote, Final Cut Pro, and the Adobe suite brings pedigree to every demo. Above all, her work is about making AI-based apps feel fluid and open rather than rigidly formulaic, always unearthing fundamental questions about what it means for humans and AI systems to collaborate usefully, with care.

With Moon, she has concentrated on AI-based applications specifically for Apple platforms, gaining deep understanding of how intelligent interfaces can integrate seamlessly with users' existing workflows and creative processes. Her work represents a singular perspective on human interface design for AI, one that prioritizes human agency, creative expression, and the compositional possibilities that emerge when AI is treated as a medium rather than just another tool.
