Reasoning about Programs With Effects

AbstractThis note presents a summary of my research on reasoning about programs with effects. This work has been carried out in collaboration with several colleagues over roughly the past ten years. The work has had two major sub-themes: reasoning about functional programs extended with imperative features; and reasoning about components of open distributed systems. Functional programming languages extended with imperative features include languages like Scheme and ML as well as object-based languages such as Java. This work has focused on operationally based semantics and formalisms for specifying and reasoning about such programs. The work on components of open distributed systems has been based on the actor model of computation and has focused on developing semantic models for modular specification and composition of actor systems
