Joshua Grubbs, Ph.D., is an Associate Professor at the University of New Mexico and an investigator at the Center on Alcohol, Substance use, And Addictions, where he studies compulsive sexual behavior disorder, gambling disorder, and personality traits. He is especially interested in the social construction of addiction and understanding what leads people feel out of control in their behavior. More simply, he studies how people come to think of themselves as having a behavioral addiction and why people might arrive at the conclusion that they have a behavioral addiction.   Additionally, Dr. Grubbs is especially interested in veteran health and the experiences of U.S. Armed Forces veterans dealing with compulsive, excessive, or out-of-control behaviors.

Beyond Work Activities

Dr. Grubbs is an avid outdoorsman who enjoys all the amazing activities that New Mexico has to offer such as hiking, fishing, mountain biking, and off roading. He is also a self-described barbecue afficionado, and when he’s not working on spending time with his family, you can probably find him smoking a pork shoulder for 22 hours or roasting chiles on his smoker.

Dr. Grubbs directs the Behavioral Addictions And Associated Disorders (BAAAD) Lab.  The BAAAD lab is primarily concerned with understanding the causes and associates of the so-called behavioral “addictions.”  Lab members’ works have focused on harm reduction in gambling, the interaction of social context and individual differences in predicting compulsive behavior, the influence of morality and religious belief on self-perception in addiction, and the experiences of minoritized individuals as they relate to behavioral addictions. Current members of the BAAAD Lab at UNM are:
