Professor of Mechanical Engineering and Applied Physics
Professor Daraio focuses on materials science, condensed matter physics, and solid mechanics. Her lab is primarily interested in:
1. Developing a physical understanding of how stress propagates in nonlinear, ordered and disordered solid media at length scales ranging from nanometers to meters.
2. Studing the fundamental connections between structure and function in different physical domains (temperature sensitivity, electrical conductivity, etc.).
3. Exploiting this understanding for the creation of new materials and devices for engineering applications ranging from optomechanics to shock absorption.
To achieve these goals, her research takes advantage of nonlinearities in local material interactions (e.g., Hertzian contact interactions between particles or nonlinear interactions between nanostructures) to create novel systems and new materials with unprecedented global properties. These materials are composite systems in which typically basis elements that interact are arranged in well-defined geometries, such that the aggregate system as a whole exhibits properties that are not usually found in natural systems and can be exploited in engineering applications. Our work is primarily experimental, but it is informed by numerical and analytical studies, which serve as a guide in metamaterial construction and validation of their properties.

Jean-Lou Chameau Professor of Control and Dynamical Systems, Electrical Engineering, and Bioengineering
Doyle's research is on theoretical foundations for complex tech, bio, med, neuro, and social networks integrating control, communications, computing, and multiscale physics. Layered architectures such as brains integrate high level planning with fast lower level sensing, reflex, and action and facilitate learning, adaptation, augmentation (tools), and teamwork, despite being implemented in energy efficient hardware with sparse, quantized, noisy, delayed, and saturating sensing, communications, computing, and actuation, on time scales from milliseconds to minutes to days. We are developing a mathematical framework that deals with all of these features and constraints in a coherent and rigorous way with broad applications in science, technology, ecology, and society.
