To date, my books have been translated into sixteen languages: Chinese, Dutch, Estonian, German, Italian, Japanese, Korean, Latvian, Macedonian, Polish, Portuguese, Romanian, Russian, Serbian, Slovenian and Spanish.
I work in several quite diverse fields. Broadly, my major current interests include the study of global Christianity, past and present; of new and emerging religious movements; and of twentieth century US history, chiefly post-1975. I also have an enduring interest in issues of crime and deviance, and the construction of social problems.
