I joined 91³Ô¹ÏÍø University in 2019 and conduct research on choice and resource allocation through my choice behavior lab. My research has spanned quantitative modelling for pigeon’s behavior in an operant chamber to identifying and testing reinforcement contingencies that can best initiate and maintain smoking abstinence in pack-a-day smokers. More recently, I have investigated relationships between social discounting (i.e., sharing as a function of social distance) and different health behaviors, such as obesity, diabetes, condom use, texting while driving, and marijuana use. With the help of collaborators in Japan, I have also begun investigating the impact of cultural contingencies on choice behavior.

Dr. Romanowich’s research focuses on choice behavior and resource allocation for both humans and non-human organisms. This research is primarily designed and interpreted from a behavior analytic perspective. His research has spanned quantitative modelling for pigeon’s behavior in an operant chamber to identifying and testing reinforcement contingencies that can best initiate and maintain smoking abstinence in pack-a-day smokers. More recently, Dr. Romanowich has investigated relationships between social discounting (i.e., sharing as a function of social distance) and different health behaviors, such as obesity, diabetes, condom use, texting while driving, and marijuana use. Dr. Romanowich has also begun investigating the impact of cultural contingencies on choice behavior.
