|To put it most generally, my work is motivated by a particular interest in how small scale definitions result in large scale features, when massively iterated. There is a deep history (and growing) of support for the idea that this is how many natural systems work (though this alone may be insufficient justification for the method - demonstrations of functional engineered systems, on the other hand...). This extends to topics like how peoples' abilities to make their own technological solutions affects social, political and economic environs.|
|My current laboratory work focuses on Digital Composites - three dimensional structures made from discrete fiber composite parts, which are part of our work on digital materials and fabrication in general. This refers to systems composed of discretized and fungible building blocks that provide both physical structure and various forms of functionality, as well as the information required to perform the building process. The implications of these systems, in terms of material and energy resource usage, are revolutionary, and well beyond the capabilities of conventional rapid prototyping (eg., 3d printers).|
|I did my PhD work at the Center for Bits and Atoms (CBA), in the Physics and Media (PHM) Group of the MAS Department (a.k.a. the Media Lab), at the Massachusetts Institute of Technology (MIT). I designed and studied reversibly assembled cellular composite materials (digital composites) as continuous materials, as well as methods for assembling digital materials. Since they are unusually light-weight, strong, and stiff, we are now working on applications like structures for things that fly. My background includes work in the fields of architecture, computer science, land planning, environmental psychology, and plant biomechanics, including an m.s. from MIT and a b.arch. from Cornell University. I like to explain how these all fit together - just ask!|
