My name is Austin Ward and I am currently a PhD student at the School of Information and Library Science at UNC Chapel Hill. Prior to starting my PhD I received my Masters in Library and Information Science from Louisiana State University and Bachelors of Science in Computer Science from the University of Louisiana at Lafayette.

My research interests include human-computer interaction (HCI), interactive information retrieval (IIR), and usability across web, virtual reality, and augmented reality technologies. I have developed search assistance tools for the web and a variety of simple search applications for the Oculus Quest VR HMD, HTC Vive, and Microsoft HoloLens, several which have been used in user studies.

I am supervised by Prof. Rob Capra.
