How do people acquire new knowledge? How do we reason about the world? My scientific work in this area uses a mix of computational modelling and experimental work to explore these questions. I also write about research methods. What is the relationship between scientific and statistical inferences? How should researchers choose between competing theoretical models? My work also explores these ideas.
I have several R packages and other software at varying stages of development:
- Some tools aid behavioural scientists: the jaysire package provides a method for writing behavioural experiments within R that can run through a web browser, and the lsr package accompanies my introductory statistics textbook
- Some packages are useful in literate programming. I use bs4cards to create the thumbnail images on this site. The site itself is built using the simple calade hugo theme I wrote, and my art website is an example of a diziet themed site
- Some packages exist as a small source of joy: the rainbowr package provides a way to generate LGBTIQ themed R hex stickers
- Finally, there are the art packages: asciify, jasmines, scrawl, flametree, turmite59, and so on. These are mostly for my own joy, but I also use them in my R classes to help students to learn programming concepts
Texts and tutorials
One of my joys in life is writing tutorial articles and technical documentation for open source projects. In addition to writing the surprisingly successful learning statistics with R textbook, I’m currently collaborating with Hadley Wickham and Thomas Lin Pederson to write a third edition of the ggplot2 book. I am also weirdly passionate about creating accessible data science tutorials that I post on my youtube channel, and making my data science course materials open and freely available to the general public. In addition, I sometimes include tutorials and explainers on my blog.
R-Ladies is a worldwide organisation that promotes gender diversity within the R community. The organisation is explicitly LGBTIQ friendly and aims provide support across the entire spectrum of roles whether as leaders, package developers, conference speakers, conference participants, educators, or users. In collaboration with Jen Richmond, Lisa Williams, Steph Stammel I co-founded R-Ladies Sydney in 2018, and it’s been one of the most rewarding professional activities I’ve ever been involved in.
I have held editorial positions one of the top scientific journals (Science) and one of the top journals in psychology (Psychological Review). In addition I have served as an associate editor at three top journals in cognitive science and cognitive psychology: Cognitive Science, Behavior Research Methods, and Open Mind.
