MEAM Seminar: “Kirigami: Programming Cutting and Folding from Microscale to Meter Scale”
Programmable shape-shifting materials can take different physical forms to achieve multifunctionality in a dynamic and controllable manner. By introducing holes and cuts in 2D sheets, we demonstrate dramatic color and […]
MEAM Seminar: “Active Colloids in Nematics for Micro-robotics and Reconfigurable Systems”
Active colloids in nematic liquid crystals are exciting vehicles for materials manipulation. Colloid shape, surface chemistry and dynamic displacement can be designed to introduce defects whose non-linear dynamics generate new […]

MEAM Seminar: “The Role of Manipulation Primitives in Building Dexterous Robotic Systems”
In this talk I will illustrate four different perspectives that we as a community have embraced to study robotic manipulation: 1) controlling a simplified model of the mechanics of interaction […]
MEAM Seminar: “Time and Rate Dependent Fracture of Polymer Gels and Interfaces”
Fracture of materials and interfaces is often time and rate dependent. The underlying mechanisms for the time and rate dependent fracture may include local molecular processes, viscoelasticity, and poroelasticity (solvent […]
MEAM Seminar: “Soft-Matter Engineering for Robotics and Wearables”
Progress in soft lithography and soft materials integration have led to extraordinary new classes of soft-matter sensors, circuits, and transducers. These material technologies are composed almost entirely out of soft […]
MEAM Seminar: “Deep Learning and Uncertainty Quantification: Methodologies and Applications”
Uncertainty is ubiquitous in physical and engineering science because of the lack of knowledge, inaccuracy in measurements, objective stochastic nature. “You cannot be certain about uncertainty”. Uncertainty quantification plays an […]
MEAM Seminar: “Metal and Air Generate Power for Robots”
In many cases, the size and weight of energy storage technologies required to power robotic systems are too large or massive for a robot to carry, leading to limited operational […]
MEAM Seminar: “Accelerated Design of Heterogeneous Materials for Improved Failure Characteristics”
Nature provides countless examples of the use of heterogeneity to enhance the failure properties of materials. Many biological materials, such as bone, marine shells, and fish scales, are extremely resilient […]
MEAM Seminar: “A Differential Homogenization Framework for Precipitation Strengthened Metals”
Precipitation-strengthened alloys are a commercially important class of materials because their mechanical properties can be altered by changing the microstructure through heat-treatment. Specifically, precipitates are introduced into the bulk (matrix) […]
