Diego Elias Costa
Hi, I am Diego and welcome to my academic space!
I am an Assistant Professor in the Computer Science and Software Engineering (CSSE) department of Concordia University
- If you are interested in joining my research group, please check the prospective students page.
Before, I worked as an Assistant Professor with the Computer Science department at UQAM in Montréal, Canada. I was a postdoctoral researcher at Concordia University, Canada, working with Prof. Emad Shihab. I received my PhD from Heidelberg University, Germany in the Parallel and Distributed Systems Group of Prof. Andrzejak.
I am interested in Software Engineering Research. In a few words, I want to reduce the burden on software developers by tackling aspects related to software maintenance and software performance. I like to leverage historical project data (e.g., GitHub) through Data Mining methods and apply Machine Learning and Statistical Analysis techniques to understand the problems developers face and provide insights/solutions to alleviate the issues.
For details about my research, please check my publication list.
Research Interests
- Software Engineering
