The Essence of a New Day

This is a new day. You have been given this day to

use as you will. You can waste it or use it for good.

What you do today is important because you are

exchanging a day of your life for it. When tomorrow

comes, this day will be gone forever; and in its place

will be something you have left behind...

let it be something good.

Research Interests

I have two main streams of research, both of which revolve, in a broad sense, around employee performance and work behavior. My first stream of research focuses on predicting, defining, and examining employee performance and work behavior and the influences work attitudes and contextual factors can have on employee performance. My second stream of research focuses on counterproductive work behavior (CWB), or behavior that is counter to effective employee job performance.

My first stream of research focuses work performance. One aspect of this work addresses personnel selection and the prediction of job performance using individual difference variables such as cognitive ability and work attitudes (e.g., job satisfaction, organziational committment). I have done research on employee selection assessment centers, individual performance in work settings (e.g., the impact of job insecurity on employee performance), and employment testing and the use of personnel tests in employee selection. Other projects focus on the extent to which employees enact the core values espoused by their organizations in their daily performance behaviors and whether such values enactment has an impact on important organizational outcomes such as employee turnover and promotion. Lastly, recent and current projects look at creativity as a desirable work outcome and focus on the degree to which individual creativity levels are impacted by situational and contextual characteristics (e.g., what impact does job insecurity have on individual creativity, and can individual employee creativity levels be changed by educational efforts in the context of an MBA course).

My second stream of research studies counterproductive work behavior (CWB). CWB can be described as behavior that violates the norms of the organization and in doing so harms the organization, its members, or both. This is, CWB is employee behavior that organizations hope to minimize. My research examines the relationships between various types of counterproductive work behavior as well as focusing on other variables and influences that might impact whether employees will engage in CWB (e.g., will employees who perceive their jobs to be very insecure engage in more or less CWB?). A newer addition to the research stream includes examining how likely employees are to report CWB on the part of other employees.
