About

I am a Senior Lecturer (eq. Associate Professor in North America) in mobile systems and HCI and I run together with Prof. Holger Regenbrecht the HCI group at the University of Otago. I was previously a senior research at the Institute for Computer Graphics and Vision (Graz University of Technology, Austria) where I also obtained my PhD.

My main research interest is location-based mobile interfaces, where I work at the intersection of HCI, Computer Graphics, Computer Vision and Pervasive Computing. Previous to my work on mobile devices, I worked in the field of Spatial Augmented Reality and Holographic displays. My research methodology is both bottom-up (build and evaluating technology and interfaces) and top-down (application-driven). Over the years, I was involved in various academic and industrial projects as well as I am an active member within an international research community.

Note to students: The University of Otago is a great place to study, offers a very good research environment, and I do my best in offering interesting thesis topics and good supervision. Please feel free to contact me if you are interested in working with me (Interns/Master/PhD/) but make clear why you want to work with me and what experience you have on Mobile Systems/HCI. I also have a good overview about funding opportunities and scholarship options. Please also check our group page for more information: HCI group at the University of Otago

Teaching

My teaching responsibilities include general topics in information science, programming for mobile devices and in particular mobile HCI and visual interfaces.  In 2017 I am the paper coordinator for INFO203 - Human-Computer Interaction and User Experience - which is being offered for the first time; INFO351 - Special Topic: Human-Computer Interaction, also offered for the first time.

In 2015 and 2016, I was involved in:

TELE303 ("Mobile Systems")

TELE404 ("Mobile Systems")

INFO221 ("Application Software Development")

INFO213 ("Business ICT Strategy")

INFO340 ("Interactive System Design") now offered as INFO351

INFO350 ("Special Topic - Mixed Reality Systems")

INFO410 ("Multimedia User Experience - Theory and Practice")

INFO470 ("Special Topic - Mobile interface/Mixed Reality Systems")

BSNS106 ("Information and Communication in Organisations") 

I further offer several projects and thesis options in the domain of mobile computing and HCI. Please contact me for a list of topics or come to my office for a chat.
