Research interests


My research interests revolve around effect handler oriented programming, a novel programming paradigm centred around effect handlers, which empowers programmers to build modular and scalable interactive software, enabling the development of safe, secure, reliable, and robust applications. My work focuses mostly on the foundations for effect handler oriented programming.

My research programme aims to push effect handlers into systems, and in particular systems programming languages, to provide a principled means for controlling the effectful nature of systems. A particular interest of mine is applications of effect handlers in operating systems as many concepts in this space have elegant and modular formulations in terms of effect handlers.
