Scientist, Professor, Speaker

University of New Mexico


I am currently an associate professor in the PCSAS Accredited Clinical Science Ph.D. program in the Department of Psychlogy at the University of New Mexico. I am also an investigator in the Center on Alcohol, Substance use, And Addiction (CASAA) at the University of New Mexico.

My research (and the research of the BAAAD lab) is primarily concerned with the scientific study of addiction, personality, and morality (particularly as it relates to addiction and personality).

The largest portion of my current research program is concerned with addiction. I am particularly interested in topics related to behavioral addictions or compulsive behavior patterns. My specific interests in these domains are related to the social construction of addiction. I’m also interested in the social and structural factors that shape self-perceptions of potentially addictive behaviors. Ultimately, I want to understand how self-reported beliefs about addiction influence presentation of symptoms, which, in turn, influence diagnosis, classification, and treatment of addictive behaviors. I have past and ongoing projects related to pornography use, compulsive sexual behavior more broadly, and excessive gambling behaviors.

In addition to these domains, I am also interested promoting replicability, reproducibility, and transparency in the scientific process. I strive to conduct my research in accordance with current standards of transparency and openness, and I encourage my students to do the same. You can find more information about my current projects at my Open Science Framework page and a complete list of my publications at my Google Scholar page.
