He has conducted extensive long-term research supported by the National Science Foundation comparing group dynamics of over-wintering crews at the American South Pole Station, with those at the Polish, Russian, Chinese, and Indian Antarctic Stations.  In addition, he is interested in network models of complex biological systems and has been working on the application of continuous time Markov chain and exponential random graph models to the study of trophic dynamics in food webs. His most recent work, funded as a MURI  by the Office of Naval Research, involves the development of methods for the reliable tagging, coding and network modeling of large corpora of related texts. His most recent research, funded as a MURI by the Army Research Office, focuses on network models of climatic and environmental drivers of human mobility (migrants, refugees).   He has published extensively in anthropological, sociological, biological and marine science journals and was the founding editor of the Journal of Quantitative Anthropology, and co-editor of the journal Human Organization. He is currently an associate editor for the Journal of Social Structure and the journal Social Networks.  Johnson is the Director of the Summer Institute for Research Design in Cultural Anthropology funded by the National Science Foundation and is the author of Selecting Ethnographic Informants, Sage, 1990 and is co-author (with Borgatti and Everett) of the book Analyzing Social Networks (1st Ed), Sage, 2013, .Analyzing Social Networks (2nd Ed), Sage, 2017, Analyzing Social Networks in R (Borgatti, Everett, Johnson, and Agneesens), Sage, 2023, and Analyzing Social Networks (3rd ED , Borgatti, Everett, Johnson, and Agneesens), Sage, 2024.
