I'm interested in software engineering, formal methods, and cybersecurity, with my research broadly addressing the problem of engineering correct and secure software/systems.
I have worked on techniques for testing/defending cyber-physical systems using fuzzing and machine learning, tools for analysing execution models of concurrency APIs, and logics for reasoning about the correctness of graph-rewriting programs.
Get in touch if you fancy a chat on any of the work! We're always keen to collaborate.
Some recent and recent-ish projects include:
See my CV for project funding details.
PDF postprints and bibliographic data of papers I have co-authored are available below.
You can also refer to my listings on DBLP, Google Scholar, or ORCID.
