Dr. Randall Sell is an Associate Professor at Drexel University’s School of Public Health, in the Department of Community Health and Prevention. His most recent work has focused on critically examining demographic variables. This work originated in Dr. Sell's research on defining and measuring sexual orientations, and sampling sexual minorities for public health research. Dr. Sell has researched and published on the history and best practices of sampling homosexuality (Sell and Petrulio, 1996; Sell 1997; Sell and Bradford, 2000; Sell and Silenzio, 2006; Sell, Kates and Brodie, forthcoming), has created an assessment of sexual orientation (Sell, 1996), and was one of the first to estimate the prevalence of lesbians, gays and bisexuals in a probability sample of the United States, United Kingdom, and France (Sell et al., 1995). Dr Sell has also examined and reported on the importance of routinely including sexual orientation variables in public health data collection activities (Sell and Becker, 2001; Sell, forthcoming), and he serves as a consultant to an ever-increasing number of surveys and programs that have begun to collect sexual orientation data. He also created and maintains the website www.GayData.org.
