Mario L. Small, Ph.D., Grafstein Family Professor at Harvard University, is the author of award-winning books and articles on networks, poverty, organizations, culture, methods, neighborhoods, institutions, and other topics. He is currently using large-scale administrative data to understand isolation in cities, studying how people use their networks to meet their needs, and exploring the epistemological foundations of qualitative research. His latest book is Someone To Talk To (Oxford). A study of how people decide whom to approach when seeking support, the book is an inquiry into human nature, a critique of network analysis, and a discourse on the role of qualitative research in the big-data era.
