Andrew Sears is a Professor and Chair of the Information Systems Department at UMBC. Dr. Sears' research explores issues related to human-computer interaction with recent projects investigating issues associated with mobile computing, speech recognition, information technology (IT) accessibility, and the difficulties IT users experience as a result of their work environment or tasks. His research projects have been supported by Aether Systems, IBM, Intel Corporation, Microsoft Corporation, Motorola, Platinum Technologies, NASA, NSA, and the National Science Foundation. He is on the editorial board of the International Journal of Human-Computer Interaction, Universal Access in the Information Society, and the Journal of Organizational and End User Computing. He served as Conference and Technical Program Co-Chair of the Association for Computing Machinery's Conference on Human Factors in Computing Systems (CHI 2001), the Program Chair for the ACM SIGACCESS Conference on Assistive Technology (Assets 2004), and has been on the program board for a variety of events including the Mobiquitous, MobileHCI, ERCIM User Interfaces for All, HCII, and UAIS conferences and workshops. He routinely consults for organizations and corporations on issues related to interactive systems design and evaluation. He earned his BS in Computer Science from Rensselaer Polytechnic Institute and his Ph.D. in Computer Science with an emphasis on Human-Computer Interaction from the University of Maryland - College Park.
