Hello, there!

My name is Leif Singer. I am a Postdoctoral Fellow at the University of Victoria in BC, Canada. My supervisors are Margaret-Anne Storey and Daniel German. I completed my PhD at the Software Engineering Group of Leibniz Universität Hannover in Germany.

I am researching the influence of social media on software engineering — the changes, opportunities, and challenges they bear. I strive to translate my findings into practical applications that support software developers in their daily collaboration.

I'm @lsinger on Twitter. Say hello there, or send me an email!

On Testing Culture in GitHub Projects Sep 17, 2012

Previous research suggests that the publicity on GitHub that is making developers' actions and interactions more visible might have an effect on how software development practices are communicated and how they diffuse in projects. My colleagues (Raphael Pham, Olga Liskin, Fernando Figueira Filho,... read more

Mutual Assessment in the Social Programmer Ecosystem Jun 2, 2012

Developers use social media sites to communicate, collaborate, connect with each other, and even for competition. These sites and their users create a social programmer ecosystem with dynamics that are the subject of ongoing research. Recently, websites have appeared that create profiles from dev... read more
