Influence of Confirmation Biases of Developers on Software Quality: an Empirical Study
Published in Software Quality Journal, 2013
In this paper, we provide a metric scheme to measure confirmatory behaviour of software developers (i.e., confirmation bias) during their daily practices (e.g., unit testing). In order to assess the effectiveness of the metrics scheme, we perform an empirical study to predict defective parts of software.

Towards a Metric Suite Proposal to Quantify Confirmation Biases of Developers
Published in Proceedings of The 7th International Symposium on Empirical Software Engineering and Measurement (ESEM), 2013
In this paper, In this research, we propose a metric suite that measures confirmation bias of software practitioners. The metrics suite is designed to be used by practitioners during their daily decision making.

[Example course materials: Download here.] Students learn about algorithm complexity, recursion, sorting algorithms, and data structures (e.g., linked lists) and abstract data types (e.g., stacks and queues). In Spring 2018 term, I designed the course from scratch. In Spring 2019 term, I redesigned this course introducing three more course components besides lectures so that this instance consisted of the following course components: (1) Lectures, (2) hands–on programming sessions, (3) problem sessions and (4) supervision sessions. I prepared all course material of each component from scratch.
