Faculty culture and communication networks are pivotal components of technology transfer on university campuses. Universities are focused upon diffusing technology to external clients and upon building structure and support systems to enhance technology transfer. However, engaging faculty members in technology transfer requires an internal diffusion of new ideas that are largely dependent upon faculty culture. New policies, structures, and support staff help to promote technology transfer ideologically, but are of little use if faculty researchers avoid involvement because of more intangible factors. the current study investigates this internal diffusion on one campus, using interviews with faculty members, administrators, technology transfer office personnel, licensees, and spin-off company administrators. Results show that faculty culture concerning technology transfer is dependent upon informal communication networks, principles of diffusion, history, and social interaction.
