Niels Ebbe Jacobsen is a User Experience Manager at Nokia. He holds a M.Sc. in Computer Science and a Ph.D. in Human-Computer Interaction both from Copenhagen University, Denmark. Niels has investigated Usability Evaluation Methods (UEMs) from various perspectives. Particularly Niels has found a substantial evaluator effect of UEMs like Thinking-Aloud Techniques, Usability Tests, Heuristics Evaluation and Cognitive Walkthrough. This work has been done in cooperation with Morten Hertzum, Bonnie John and Rolf Molich.

Niels' research interests also include Philosophy, Cognitive Psychology, and text input systems for mobile devices.

At Nokia Niels was a Usability Specialist working on software interaction design first in Denmark and then in the UK. Later Niels focused on ergonomics and industrial design in a concepting team until he became User Experience Manager in Nokia Mobile Phone's Business Development Management.
