Hans Hallez is a lecturer (Docent) of physics and informatics to 1st year (freshmen) academic bachelor Industrial Engineering students. This is within the faculty of Industrial Engineering (FIIW) of the KU Leuven (TechnologyCampus Oostende). In the final master year, he also teaches "optoelectronic communication" to electronic engineering students.

His research interests are within electronic implementation for medical and industrial applications. More specifically his interest lies in the implementation of signal-processing algorithms within programmable wireless sensor networks. He is also interested in new sensors and measurement techniques.

Hallez is proficient in conducting research concerning electronics, physics and ICT with medical applications. From the more fundamental research on EEG and ECG signal processing at the UGent, he's gone to research on a demand-driven and practical basis at KU Leuven. There he is responsible for teaching and conducting research.
