Dr. Rosopa is an Assistant Professor in the Department of Psychology at Clemson University. He earned his Ph.D. (2006) and M.S. degrees from the University of Central Florida and B.S. degree from Tulane University. His research has been published in such outlets as the Encyclopedia of Measurement and Statistics, Organizational Research Methods, and Research in Personnel and Human Resource Management.
Dr. Rosopa’s research interests are in two broad areas—quantitative methods and topics germane to organizational psychology. Utilizing his knowledge gained while pursuing a master’s in statistical computing, he blends statistics and organizational research. Generally, his quantitative interests can be classified into applied statistical modeling (viz., linear models and linear mixed models) and computer-intensive methods (e.g., Monte Carlo simulation). For example, within linear models, his generalization of a weighted least squares approach to detect regression slope differences under conditions of heteroscedasticity across groups has been shown to control Type I error rates and provide increased statistical power compared to some extant procedures. In addition, his approach is computationally simple compared to the statistical approximations. This has implications for human resource selection, research on aptitude by treatment interactions, and other areas.
Dr. Rosopa’s substantive research interests include mentoring, citizenship behavior, stereotypes, fairness in the workplace, and cross-cultural issues in organizational research. As an example, he is currently working on a set of studies where the preliminary analyses suggest that certain gender-based and ethnicity-based minority groups are “stereotypically expected” to engage in helping behaviors in the workplace. When they do not engage in these behaviors when they “ought to,” they may experience negative outcomes (e.g., lower performance appraisal ratings) which their counterparts in the majority group do not experience.
Dr. Rosopa has various applied experience in the public and private sector. Some previous work involves workforce development at Workforce Central Florida, mentoring and training research while a Research Fellow at the Naval Air Warfare Center Training Systems Division (Navair-Orlando), test equating and longitudinal statistical modeling for RSK Assessment, and experience as a data analyst for Talent Keepers, a human resource consulting firm.
