I am a Toronto-based researcher investigating the social side of software work, with a particular attention to globalization, open source, and software preservation. My first book, Coding Places: Software Practice in a South American City was published this year by the MIT Press.

Some projects

	Software in Brazil. I have recently published a book Coding Places: Software Practice in a South American City (MIT Press, 2012), describing an ethnographic study of software developers in Rio de Janeiro, Brazil. One of the topics that I explore is the community formed around Lua — a programming language developed in Rio de Janeiro that has been recently gaining in popularity.
	Geography of Open Source. This new project, sponsored in part by GRAND NCE, explores geographic dimensions of open source development. (In a related project, we also looked at a geography of Twitter.)
	Software Preservation. This project, supported by SSHRC, looks at a number of issues in software preservation. We are just starting, so please be patient.
	In addition to the academic projects, I also write software for fun sometimes. Google seems to think that writing a Python implementation of Markdown is the most important thing I have done in my life so far. I also wrote a wiki in Lua while doing my fieldwork.
