Jack is an associate professor at the University of Hawai‘i at Mānoa in the Department of Psychology.  His primary research interests include understanding the role of neighborhood stress in the formation and maintenance of health disparities, ecological assessment, quantitative methods and statistics, and program evaluation. Jack earned his doctorate in community psychology from Georgia State University in 2010 and earned a bachelor of science degree in health science and a master of science degree in experimental psychology from Old Dominion University. 

Jack's research centers around ecological determinants of health-related quality of life. This line of research includes the study of individual-level factors, such as adverse childhood experiences and multiple chronic medical conditions, as well as neighborhood-level factors, such as housing, crime, and poverty. Methodologically, Jack is particularly interested in the use of multilevel structural equation modeling techniques to estimate individual and contextual effects for health-related quality of life and well-being outcomes. 

Education, considered as a process of forming our mental habits and our outlook on the world, is to be judged successful in proportion as its outcome approximates to this ideal; in proportion, that is to say, as it gives us a true view of our place in society, of the relation of the whole human society to its non-human environment, and of the nature of the non-human world as it is in itself apart from our own desires and interests.
