Denys Matthies

Denys J.C. Matthies is currently a Research Fellow at the Bioengineering Institute at the University of Auckland. Before he worked at several other research institutes, such as at the Fraunhofer IGD Rostock in Germany, at the NUS HCI Lab in Singapore, and at the Telekom Innovation Laboratories in Berlin.

Denys received a Doctoral Degree from the University of Rostock, a Master's Degree from the University of Munich (LMU) and a Bachelor's Degree from the University of Applied Sciences Potsdam (FHP).

Since 2011, Denys conducts research in the domain of Human-Computer Interaction, while his main research interest lies in augmenting humans with wearable technology. Since 2012, he serves as a reviewer for many conferences and journals, including: CHI, MobileHCI, TEI, WHC, INTERACT, and iWOAR.
