Dr. Deaner's research primarily investigates sex differences in human behavior, with particular emphasis on competitiveness, sports performance, and evolutionary adaptations. His work spans multiple domains including laboratory studies, field research in sports settings, and analysis of large-scale competitive data. A significant portion of his research examines how evolutionary pressures may have shaped distinct behavioral patterns between men and women, particularly in competitive contexts. His studies often bridge theoretical evolutionary frameworks with empirical data from contemporary settings, including sports competitions, gaming environments, and social interactions.

Analysis of Dr. Deaner's recent publications (2014-2022) reveals a consistent focus on sex differences in competitive behavior across diverse contexts. His work demonstrates methodological diversity, employing both experimental and observational approaches across laboratory, field, and archival settings. Key thematic areas include the evolutionary basis of sex differences in sports performance, competitiveness in digital environments like MMORPGs, and the relationship between biological factors and behavioral outcomes in competitive situations. His research often challenges conventional explanations by applying evolutionary frameworks to contemporary behavioral phenomena.

Dr. Deaner teaches courses including PSY300 (Research Methods in Psychology), PSY315 (Psychology of Sex Differences), and PSY375 (Comparative Psychology), providing students with opportunities to engage with his research interests. His office is located in Au Sable Hall at Grand Valley State University, where he maintains regular office hours for student consultation and research discussion.
