Randolph Bias


After receiving his Ph.D. in cognitive psychology from UT-Austin, Randolph worked in industry for over 20 years as a UX professional/manager, helping software developers make human-computer interfaces user-centered. After stints with Bell Labs, IBM, and BMC Software (where he created and managed the Usability Department), Randolph co-founded an independent usability lab and consultancy. In 2003 he came to the School of Information to research human information processing and human-computer interaction and to help train the next generation of UX professionals. Randolph has published over 80 technical articles and co-edited two editions of _Cost-Justifying Usability_ (R. G. Bias and D. J. Mayhew, Eds., 1994, 2005, Morgan Kaufmann). He is a Certified Human Factors Practitioner, and is active in professional societies such as the Human Factors and Ergonomics Society and the User eXperience Professionals’ Association (UXPA). Randolph has taught undergraduate and graduate courses in psychology, information studies, and statistics at The University of Texas at Austin, Rutgers University, Huston-Tillotson University, Texas State University, and the Universidade NOVA de Lisboa, plus has taught many short courses for industry. In 2017 he was awarded the UXPA’s Lifetime Achievement Award. Randolph is a vigorous advocate for designing technology to fit the user. In his retirement he has launched a UX consulting effort, UXonSpec, with a creative twist: www.uxonspec.com.
