My main interests are system dynamics and multi agent simulation used for support of business and marketing decisions (e.g. modeling of consumer markets) and in business education (e.g. development of open source business simulators). Amongst my other interests are applied marketing research, relationships between academia and industry, financial literacy, mind and concept mapping.
Human and environmental interactions in the Mediterranean region. Currently working on influence of agricultural terraces on landscape evolution.
The big picture question driving my research is how do complex systems of interactions among individuals / agents result in emergent properties and how do those emergent properties feedback to affect individual / agent decisions. I have explored this big picture question in a number of different contexts including the evolution of cooperation, suburban sprawl, traffic patterns, financial systems, land-use and land-change in urban systems, and most recently social media. For all of these explorations, I employ the tools of complex systems, most importantly agent-based modeling.
My current research focus is on understanding the dynamics of social media, examining how concepts like information, authority, influence and trust diffuse in these new media formats. This allows us to ask questions such as who do users trust to provide them with the information that they want? Which entities have the greatest influence on social media users? How do fads and fashions arise in social media? What happens when time is critical to the diffusion process such as an in a natural disaster? I have employed agent-based modeling, machine learning, geographic information systems, and network analysis to understand and start to answer these questions.

Grant Snitker, M.A., is a doctoral candidate in archaeology at Arizona State University and a National Science Foundation Graduate Research Fellow. His research focuses on prehistoric uses of controlled fire, settlement history, and environmental change. Snitker approaches these topics through geoarchaeology, archaeological survey methods, GIS modeling, and landscape/fire ecology. He currently works in Spain investigating the origins and evolution of early farming communities (7,700–4,500 cal. BP) and how they used fire to create productive agricultural landscapes. Snitker also applies his knowledge of archaeology and fire ecology as an archaeological resource advisor on wildland fire incidents here in Arizona. He works alongside firefighters to protect archaeological sites from wildfires and potentially destructive firefighting activities.
