 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*](https://global.oup.com/academic/product/someone-to-talk-to-9780190661427?cc=us&lang=en&) (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.
