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 a variety of companies (e.g., IBM, Intel Corporation, Microsoft Corporation, Motorola) and government agencies (e.g., the National Science Foundation, the US Department of Education, various state agencies in Maryland). He is Editor-in-Chief (with Vicki Hanson) of the ACM Transactions on Accessible Computing and serves on the editorial boards of the International Journal of Human-Computer Studies, the International Journal of Human-Interaction, Universal Access in the Information Society, and the International Journal of Mobile Human Computer Interaction. 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), General Chair and Program Chair for the ACM SIGACCESS Conference on Assistive Technology (Assets 2004 and ASSETS 2005 respectively), 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 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.
