His primary focus of research is to understand the impact of virtual reality (VR) on persons with disabilities and to effectively leverage the vast amount of prior VR research conducted with healthy users to drive future assistive technology and rehabilitation research. Although only a junior faculty member, John has already gained significant support from the National Science Foundation to perform basic VR research towards understanding and quantifying how mobility impaired populations interact with VR differently than healthy users. Aside from being a VR researcher and developer of assistive technology, John is also an end-user; he suffers from numerous disabilities caused by multiple sclerosis. Through this unusual lens, he offers a unique perspective for the direction of research in this area.
