I'm Felix Moser, exploring how people and AI agents work together.

I've always been drawn to solving problems and building things. I started programming while studying Informatics at the Technical University of Munich, took on freelance projects, and co-founded BO24, a digital inventory management app that now serves thousands of users. Building software for real users taught me that the hard part is rarely the code, but how people work with what has been built.

That led me into digital health: an app for epilepsy patients with the University Hospital Bonn, and a research fellowship at Yale's Digital Health Lab, where I worked on time-series policy analysis and on bringing LLMs into clinical documentation.

I'm now doing my PhD at the University of St. Gallen and the University of Zurich, within the Centre for Digital Health Interventions, and work as a voice AI researcher at ETH Zurich's Agentic Systems Lab and as an AI researcher at the Translational Clinical AI Lab. My PhD centers on STELLA, an open-source platform for auditable voice-first agents that helps bring voice AI to vulnerable populations, such as people living with dementia. I focus on digital health because it demands especially careful handling of these systems, and what holds up there is a strong basis for other domains.

The question I care about most now comes after building: how people manage, oversee, and trust teams of AI agents acting on their behalf. I explore it hands-on by running a team of agents myself, and I write about what I learn in my articles.
