Randolph Bias


Randolph has worked in industry for over 20 years as a usability engineer, helping software developers make human-computer interfaces, including Web sites, user friendly. 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. He came to the School of Information to research human information processing and human-computer interaction. Randolph has written over 50 technical articles in the area of human information processing, and co-edited Cost-Justifying Usability (R. G. Bias and D. J. Mayhew, Eds., 1994, Cambridge: Academic Press). He is a Certified Human Factors Practitioner, and is active in professional societies such as the Human Factors and Ergonomics Society and the Usability Professionals Association. Randolph has taught undergraduate and graduate courses in psychology and statistics at The University of Texas at Austin, Rutgers University, Huston-Tillotson College, and Texas State University, plus has taught many short courses for industry. He is a vigorous advocate for designing technology to fit the user.
