Otago Polytechnic


Research is key to Otago Polytechnic’s role as a tertiary education provider. A strong research culture means better education for students and a great overall benefit to the wider community. Our teaching and learning activities are underpinned by research, which means all teaching practitioners are current in their field of expertise and in their teaching practice.

This not only develops the capability of our staff, but of our students and graduates. We are drawing on our institutional strengths and core capabilities to engage with collaborators, with the professions, with industry and our communities, and we apply our expertise to help solve challenges. 


Research from David Rozado


David Rozado holds a B.Sc. in Information Systems from Boston University, a M.Sc. in Bioinformatics from the Free University of Berlin and a Ph.D in Computer Science from the Autonomous University of Madrid. David joined Otago Polytechnic early in 2015. His main area of research is in Human computer interaction with a focus on accessibility software and assistive technologies for people with motor impairment. He currently teaches Web programming 3, Databases 3 (with an emphasis in data miningmachine learning) and final year Project.
