Valentina Lenarduzzi is a postdoctoral researcher at LUT University (Finland). My research activities are related to modern software development practices and methodologies, including data analysis in software engineering, software quality, software maintenance, and evolution, focusing on Technical Debt as well as code and architectural smells. Before that, I was a postdoctoral researcher at Tampere University (Finland) and at the Free University of Bozen-Bolzano, (Italy). Moreover, I was visiting researcher at the University of Kaiserslautern (TUK) and the Fraunhofer Institute for Experimental Software Engineering IESE (Germany). I obtained my Ph.D. in Computer Science in 2015 with a dissertation on effort estimation and data analysis in software engineering.
