Let me lead your empirical and user research
I work with companies in the developer tooling space to conduct research that helps inform their mission and direction. The empirical and user research studies I lead shed light on the needs and desires of software developers. I’m also associated with the University of Zurich where I’m working as a senior researcher.
My research focuses on software engineering practice, engineering productivity, and developer happiness. My expertise lies in developer productivity, code reviews, software testing, software comprehension, and empirical studies.
From 2008 to spring 2013, I worked as a researcher at Technical University Delft in the Netherlands. Afterward, I joined Microsoft research in the UK, and by 2014 I worked in the Research and Development organization at Microsoft Redmond in the USA.
I have written dozens of scientific publications that appeared in top-tier academic and scientific journals and conference proceedings. For a more complete list, you can hope over to my scientific publications account.
Developer experience is essential for software companies as enhanced developer experience improves productivity, satisfaction, engagement and leads developers to stay longer with their company. In this study, we show the factors that affect developer experience and also identify strategies employed by individuals and teams to improve developer experience. Our findings result in an actionable, conceptual framework for understanding and improving developer experience. The framework provides a go-to reference for organizations that want to enable more productive and effective work environments for their developers.

In a large-scale study, we investigate how code reviews are done at Microsoft, which benefits they provide, and which challenges developers face doing code reviews. We also distilled several best practices for code reviewers and code authors, as well as best practices on an organizational level. Finally, we show which tool needs are predominant for code reviewing.

Code reviews offer many benefits to software teams such as knowledge dissemination and increased code quality. Still practicing code reviewing requires a substantial time commitment. In fact, code reviewing can show teams down. Find out which best practices to follow to ensure you get the most out of that practice.
How do you reduce the test suite size and the test execution time without sacrificing code quality? In this paper we explain a new approach to safely remove test cases and reduce test execution time, saving thousands of dollars in infrastructure and manual labor costs for Microsoft.

What does it mean to own software code? And what is the implication of code ownership? In this study, you can learn if and how code ownership influences code quality. You also get a concrete list of recommendations of how to ensure the best ownership models for your codebase and which anti-patterns you should avoid.
Did you ever wonder what makes code reviews useful? Do you want to improve the value of your code review comments? Then, this publication is for you. Through a large-scale study, we reveal which code review comments are valuable and which ones are just annoying and time-consuming for the code author.
