Research & Teaching Interests

The fact that talented, well-meaning people can perform poorly in one environment and suddenly boost their effectiveness when they move to another environment has fascinated Gallagher since early in his career. This interest drove him to explore the academic literature on organizational culture and, later, into the determinants of team effectiveness.

“Market orientation” has been an academic topic since the mid-1980s. Kohli and Jaworski (1990) defined market orientation as “the organization-wide generation of market intelligence, dissemination of the intelligence across departments and organization-wide responsiveness to it”

In collaboration with Linden Brown, PhD., and Christopher Brown, Gallagher helped to extend the research on market orientation and to make it more accessible to businesspeople across the globe. Their contribution was to statistically demonstrate the impact of organizational characteristics like cross-functional collaboration and strategic alignment on outcomes like customer satisfaction, innovation, new product success, and profitability.
