Post-Docs/Lecturers/Visiting Scholars Research

The Center for the Study of Complex Systems supports a diverse body of research.  Research specialties of our post-docs and researchers can range from digital currency and social constructs; power laws and fractals; statistical inference in complex networks, to computational philosophy.  Below you will find a statement about the research interests of these CSCS members, a link to their lab or personal website, a list of three recent or selected publications as well as a list of any books/book chapters and recent news. 

To see a list of faculty by 'fields of study' go to the People page and click the 'Browse: Fields of Study' drop-down near the top right of each page.  To search by LSA department, type the department name in the 'Profile Search' box above Fields of Study - ie 'sociology' will return faculty members affiliated with the Sociology Department.

Patrick Grim


Dr. Grim is a pioneer in the field of computational philosophy. He has a prolific list of publications, videos, and books in the areas of game theory, agent based modelling, epistemic dynamics, chaos, fractals and the semantics of paradox, cellular automata, omniscience, polarization are just of the few topics Professor Grim touches on.

Professor Grim frequently publishes with members of what is now the Computational Social Philosophy Lab (CSPL) - which began as a collaboration between Grim and graduate and undergraduate students who were affiliated with the Complex Systems program. Dr. Grim currently has a new group of undergraduate students he is mentoring.

Joseph Johnson

Dr. Johnson’s research focuses on the development of simple mathematical models of biological and social systems. His previous work has focused on the formation of multimodal distributions in various systems spanning the origin of name brands and generics, the emergence of sex cell size difference, and the creation of a general theory of multimodality using coupled oscillators as a test bed.

Mitchell Newberry



Dr. Newberry develops mathematical and computational theory to understand how the evolutionary process produces form and function in biology and culture. He comes from a background in Physics, Biomathematics and computation with a PhD in theoretical population genetics. He specializes in probability theory, statistical inference and models of ecological and evolutionary dynamics. He has measured constraints on the optimal morphology of circulatory systems and used population-based evolutionary models to explain aspects of how human languages change over time.
