The Environmental Structure Research Group (ESRG), see http://www.aboutus.org/ESRG, is "an interdisciplinary, international partnership of basic and applied researchers and practitioners in the disciplines of the built and natural environments, and the disciplines with which they interact".

Sergio has been envited to join the group, which he did enthusiastically.  The group is interested in "an emerging approach to design called "evidence-based design.  It seeks to analyze and to respond to the complexities of the context, rather than forcing them into a preconceived straitjacket. (...).  We are particularly interested in the ways that environmental structures can be generated, and the beneficial properties that they can have as a result of their generative structure. We are fascinated by the way that simple rule-based steps can produce a high level of complexity and adaptivity. We want to learn how certain kinds of adaptive codes can -- and in many cases did already - produce very stable, high-quality settlements. We are also interested in the analytical techniques that allow us to see and understand these processes". 

Members "represent a number of institutions from around the world, and a number of researchers and practitioners from different disciplines. We share a belief that many of the most interesting questions today are not within disciplines, but between them. The challenge is to find ways to collaborate across disciplines, sectors and national boundaries. That is a key goal of the ESRG".
