About HEIDi

HEIDi is an interdisciplinary group of scientists devoted to understanding human behavior in all its complexity. In particular, the group focuses on mapping out (preferably computationally) the important variables or properties of both individuals and their environments and how those variables influence each other over time and across levels of analysis (from biological to social). Specific recognition is given to the notion that a human’s environment often includes other humans (i.e., is social), and that models (both computational, machine, and animal) can be used to represent and test understandings of human-environmental interaction over time.
