CHALLENGE: Ebenbuild's digital lung twin had funding and validation, but the engineer-built prototype wasn't grounded in real clinical workflows. With no comparable tool on the market and a future as an FDA-regulated medical device, we needed to build something intuitive enough for high-pressure ICU environments - where bad UX could mean the difference between adoption and abandonment. MY ROLE: I led design strategy and execution with a visual designer, working directly with the PM, Engineering and C-level team. APPROACH: I conducted extensive on-site and remote research and testing with clinicians in hospitals across Germany and the US, and along with a visual design lead - helped build a design system optimized for clinical clarity. I bridged clinical needs, technical constraints, and business goals - bringing stakeholders together at key moments to align on direction. Even though branding wasn't a part of the brief, I went the extra mile to think about a brand story and come up with a visual identity that helps the tool stand out and be noticeable in a hospital setting through communication materials.
