Mark C. Pachucki

Associate Professor

I am a sociologist who investigates phenomena at the intersection of social determinants of health, social network dynamics, and culture. While it is commonly accepted that culture and social context reciprocally shape our health, understanding the structure and meanings of relationships can give additional insight into individuals' health behaviors and disparities over the life course. For more information about my current course offerings, publications, educational philosophies, research projects, and full CV, visit my personal website, which I tend to update more frequently than this one.
