Ștefan Stănciulescu

I am a postdoc at UC Davis working with Prof. Vladimir Filkov. My current research involves open source sustainability, specifically designing methods and tools to guide projects towards success and sustainability. In particular, I am applying quantitative research methods to detect patterns that successful projects exhibit, and understand how these can be transformed into actions that less successful or non sustainable projects can use. Stay tuned, this is a super exciting project!

In the past I was a Scientist at Hitachi ABB Power Grids Research (and ABB Corporate Research) in Switzerland where I worked on exciting projects related to Software Architecture, Software Testing, Programming Languages for Real Time Systems, Performance Prediction for Highly Configurable Systems, and Internet of Things. Until July 2020, I was a Scientist at ABB Corporate Research in Switzerland where I mainly focused on software engineering research.

I am very fortunate and grateful to have worked with amazing colleagues throughout my career. From 2013 to 2017 I was a doing a combined MSc and Ph.D. at IT University of Copenhagen (Denmark), supervised by Prof. Andrzej Wąsowski. During my Ph.D. I spent 6 months at University of Waterloo, with Prof. Krzysztof Czarnecki where I did most of my work on understanding forking as a variaiblity mechanism using the 3D printer firmware Marlin. The last 18 months of my Ph.D., I was a visiting scholar at Carnegie Mellon University with Prof. Christian Kästner where I continued the work on integrating cloned variants into a configurable platform as well as the work on finding features in forks with (now Prof.) Shurui Zhou.
