Here you can find the current members of the ESE research group and their contact information as well as previous members of the group.
Tomi Männistö


Tomi Männistö is professor of Computer Science at the University of Helsinki and the head the Empirical Software Engineering Research Group. His researc interests include product requirements and software architectures, software products, software intensive services, product variability and conceptual modelling. Currently, the research is also working on the software engineering paradigm called continuous experimentation in which data from real usage of software is collected and analysed for decision-making in software development. Tomi Männistö is a member and ex-chair of IFIP Working Group 2.10 Software Architecture and representative for the University of Helsinki in ISERN (International Software Engineering Research Network).

Mika Mäntylä

Mika Mäntylä is a professor of Software Engineering at the University of Helsinki in Finland. He received his D. Sc. degree in 2009 in Software Engineering from Aalto University in Finland. Mäntylä's research interests include end-of-lifecycle software engineering activities such as software testing, software maintenance, and software operations. He is also interested in systematic multivocal literature reviews and the behavioral and psychological aspects of software engineering. Currently, he applies mainly quantitative research methods from empirical software engineering and mining software repositories. Mäntylä is keen to use natural language processing, classical machine learning, and deep learning to tackle software engineering problems. He has previously worked as a full professor at the University of Oulu, as an assistant professor at Aalto University and as a post-doctoral researcher at Lund University in Sweden. His studies have been published in journals such as IEEE Transactions on Software Engineering, IEEE Software, Empirical Software Engineering, and Information and Software Technology. Mäntylä currently serves as an associate editor for IEEE Software and Empirical Software Engineering journals. For more information, please visit

Jukka K. Nurminen


Jukka K. Nurminen started as a professor of computer science at the University of Helsinki in spring 2019. He has worked extensively on software research in industry at Nokia Research Center, in academia at Aalto University, and in applied research at VTT. His key research contributions are on energy-efficient software and mobile peer-to-peer and cloud solutions but his experience ranges widely from applied optimization to AI, from network planning tools to mobile apps, and from software project management to tens of patented inventions. He received his MSc degree in 1986 and PhD degree in 2003 from Helsinki University of Technology (now Aalto University). Currently his main interests are on tools and techniques for developing data-intensive software systems including testing of AI solutions, computational moral as well as software development for quantum computers.

Petri Kettunen

Petri Kettunen, Docent, University Researcher, received his D.Sc. (Tech.) degree in 2009 from Helsinki University of Technology following an extensive industrial career mainly in telecom business. Since 2010 he has been at University of Helsinki, department of Computer Science. His current research interests include agile software enterprises, continuous innovation of software-intensive products and services, sustainability in software engineering, and future software development organizations.


Antti-Pekka Tuovinen

Antti-Pekka Tuovinen is a University Lecturer at the Department of Computer Science. Antti-Pekka's main interests are in the areas of Software Architecture (architecture and design, programming languages) and Software Engineering (quality and testing). He teaches graduate-level courses on those subjects and supervises MSC thesis writing. In addition to academic proficiency, he has extensive experience of research and development work in the IT industry from several companies.


Mikko Raatikainen,

Mikko Raatikainen is postdoctoral researcher. His research research interests include topics such as software business, service design, requirements engineering and software architecture. In particular, he is interested in complex contexts that include collabaration between the stakeholders, such as in the case of open source development, software ecosystems, and software product lines. His carries out empirical research, often in close collaboration with industry.
