Fernando Castor is, since September 2023, an Associate Professor at the Faculty of Electrical Engineering, Mathematics, and Computer Science of the University of Twente. His research activity is mainly located within the areas of Software Engineering and Programming Languages and seeks to identify efficient ways to develop software that behaves efficiently. Over the past five years, his research has focused on the energy efficiency of software systems, in particular, on how exploiting the design diversity of preexisting software components can be an inexpensive way to save energy. Furthermore, he has also been investigating how constructs for concurrency control and parallel execution management impact attributes such as performance, energy efficiency, and ease of maintenance. His research is in part experimental and in part based on the analysis of large scale open source code repositories.
