Abstract: Embryonic tissues and cancer have in common the fact that they are both highly proliferative tissues rapidly moving through the cell cycle, as opposed to most other differentiated tissues in an adult. DNA damage can arrest some embryonic cells but genetic instability is a hallmark of cancer. This thesis studies the contrasting role of […]
Self-reconfigurable modular robots are composed of a small set of modules with uniform docking interfaces. Different from conventional robots that are custom-built and optimized for specific tasks, modular robots are able to adapt to many different activities, and handle hardware and software failures by rearranging their components. This reconfiguration capability allows these systems to exist […]
It has been twenty years since the advent of the first power-autonomous legged robots, yet they have still not yet been deployed at scale. One fundamental challenge in legged machines is that actuators must perform work at relatively high speed in swing but also at high torque in stance. Legged machines must also be able […]

Suspensions of non-Brownian particles in fluids are commonly found in nature (e.g. mud, soils, and debris flows) and in the industry (e.g. paints, food, and cosmetics). Understanding the relations between the microstructure and the effective properties of these materials can provide insight into how they fail or behave during processing. Despite their ubiquity and usefulness, […]
Lightweight structures are the product of the science of making systems as light as possible with constraints, which often refer to being sufficiently strong and stiff. Although the development of lightweight structures was initially driven by the demands for better fuel and material economy, the recent advancements in microfabrication have allowed the manufacture of structures […]

Stress-induced solid-to-solid phase transitions form a large class of phase transitions in nature. They occur in materials that can exhibit different crystal structures under different conditions (stress and temperature), and when the stress and temperature condition changes, the material may undergo a transformation from one phase to another. Despite its considerable potential in application, some […]
