talks, posters, presentations

I've presented at a wide range of events over the last few years, and most of them are listed here. For publications, see my ORCID or Google Scholar pages.


At PyCon US I spoke about how CPython can adopt property-based testing and fuzz those tests with Atheris and OSS-Fuzz at the Language Summit, then presenting a tutorial introducing property-based testing (slides, video) and a poster about my autoformatter, shed. Plus my usual involvement with the maintainers' sessions, sprints, and mentored sprints - it's a busy week even before the time difference!

For SciPy, I reprised that tutorial with an emphasis on scientific and numerical programs - and also presented a shorter talk on property-based testing for scientists. Conf42 Python saw a seriously condensed talk, thanks to video editing. I told PyOhio that I wrote code to write your tests! - and gave a live demo of the Ghostwriter.

The talks continued at EuroPython, PyCon Latam, PyCon India, and PyCon Malaysia! I hope to visit them in-person in some future year.


PyCon US went virtual this year, but was still a major event. At the Language Summit I proposed writing property-based tests for CPython (demo here), which was featured on, and gave a lightning talk on improving SyntaxError for novices. I also helped organise the mentored sprints, as well as mentoring new contributors on the day.

I was invited to the Moscow Python conference, and gave my talk online. At the SciPy conference I presented an online poster, and published a paper on testing scientific code.

At PyCon Australia, I told the audience to Stop Writing Tests! (video) - announcing both the Hypothesis Ghostwriter and HypoFuzz, a new tool for adaptive fuzzing. On the social day, I coordinated the development sprints and ran an all-day mentoring event.

I was delighted to reprise Stop Writing Tests! for PyCon India and Pyjamas Ireland.


I was rather busy at PyCon US, where among other things I presented a tutorial, talk, and poster (pdf) about 'escaping from auto-manual testing' with Hypothesis. I also attended the Language Summit, spoke at the maintainers summit, and led teams at both the sprints and mentored sprints. It was a fantastic - and very intense - nine days.

At EAGx Sydney, I posed 'some questions for 21st century machines' based on my work at the Autonomy, Agency, and Assurance Institute.

At PyCon Australia I presented one of the inaugural 'deep dive' talks, on Sufficiently Advanced Testing. I think this is my best technical talk to date, and wrote up a hyperlinked transcript for this site.

At SciPy US, I gave a talk and taught a workshop on advanced testing for scientists and developers of data science tools, which I later reprised in Spain for EuroSciPy (talk, tutorial). The material for my 2019 tutorial is open source and available here.


At the European Union's Future in the Making conference, I presented a poster about 3Ai's Collaboratoria - immersive experiences bringing togther researchers, scholars and practitioners.

At PyCon Asia-Pacific, I taught a workshop on property-based testing and other insecticides. At the inaugural PyLondinium, I gave a talk about property-based testing (video) ...and an updated version at PyCon Australia.


I presented my Honours research project at the annual conference of the Australian Meteorological and Oceanographic Society. My talk won a student presentation prize, and my poster was also well received. My full Honours thesis can be read here.
