Alexandre Gomes de Siqueira, Ph.D.

Assistant Instructional Professor


Alexandre G. de Siqueira, Ph.D., is an Assistant Instructional Professor at the Department of Computer & Information Science & Engineering. His research focuses on human-centered computing and human-computer interaction. This work includes investigating the intersection between tangible user interfaces, multi-touch, augmented, and virtual reality and examining Virtual 3D Social Spaces for enhanced learning environments. He is also interested in the maker movement, and how rapid digital prototyping can be brought to the masses. He has collaborated with multi-disciplinary teams of musicians, communication scientists, psychologists, and physicians both from the academy and the industry across multiple projects.

Previously, Dr. Siqueira worked for Accenture for over ten years as a developer, team lead, manager, and consultant in diverse industries such as electricity, oil, and gas. He holds an MBA from Fudação Getulio Vargas in São Paulo, Brazil, and a Ph.D. in Human-Centered Computing from Clemson University.
