Recent and current topics

See my Google Scholar page for a more complete publication list.
Here are some selected topics and publications.
  • Design and implementation of generics for the Go programming language. Go is a programming language developed by Google, and used by many companies and organisations globally. This work is a collaboration between researchers and the Go Team at Google. The impact includes contributing to the final design of generics released in Go 1.18.

  • Theory, implementation and applications of session types. This line of work has developed languages and practical tools for formal specification and safe programming of message passing protocols for concurrent and distributed systems. It stems from industry collaborations with Red Hat, Cognizant and the Ocean Observatories Initiative.
  • Run-time deadlock verification for phasers. A generalisation of the concept of synchronisation barrier in concurrent programming that allows processes to asynchronously advance to later synchronisation phases ahead of their peers.
