My research deals with the design and evolution of complex technologies at larger scales such as organizations, governments and cities; blending methods from organizational science and software engineering, informed by domain-specific theories in business, government and cities. I primarily use design science methods, supported by interpretive and positivist approaches and enjoy reflecting on the craft of teaching. My work has been published in several premier journals and conferences. I received a Ph.D. in MIS from the Wisconsin-Milwaukee in May 1995. I have chaired DESRIST, IEEE Service Computing, WITS and ER conferences; and have served/serve on on the editorial boards for Journal of the AIS, MIS Quarterly, Information Systems Research, Journal of Database Management, Scandinavian Journal of IS, and Information Technology &Management
