Hardware platforms for socially interactive robotics can be limited by cost or lack of functionality. In this talk I will present the overall system—design, hardware, and software—for Quori, a novel, affordable, socially interactive humanoid robot platform for facilitating non-contact human-robot interaction(HRI) research. The design of the system is motivated by feedback sampled from the HRI […]

The Department of Bioengineering at the University of Pennsylvania and Dr. Michelle Johnson are pleased to announce the Doctoral Dissertation Defense of Kevin Bui. Zoom link: https://upenn.zoom.us/j/96436500457?pwd=OUVTSjNpNWp1Z0dGVnpyaVJUa0VHQT09 Meeting ID: 964 3650 0457 Passcode: 571655
Cellulose nanofibrils (CNFs) are a naturally abundant polymer and have superior mechanical properties, high aspect ratios, are transparent and biodegradable, which make them attractive to be used in structural materials. As a reinforcing phase, CNFs have the potential to improve the mechanical properties of polymer materials. While there are active research efforts aimed at incorporating […]
Thesis Title: Balancing Fit and Complexity in Learned Representations Abstract: This dissertation is about learning representations of functions while restricting complexity. In machine learning, maximizing the fit and minimizing the complexity are two conflicting objectives. Common approaches to this problem involve solving a regularized empirical minimization problem, with a complexity measure regularizer and a regularizing […]
Underwater swimmers present unique opportunities for using bodily reconfiguration for self-propulsion. Origami-inspired designs are low-cost, fast to fabricate, robust, and can be used to create compliant mechanisms useful in energy-efficient underwater locomotion. This thesis demonstrates an origami-inspired robot that can change its body shape to ingest and expel water, creating a jet that propels it […]

Abstract:Â Colloidal particles accumulate and organize at fluid interfaces via capillary interactions. We study pair interactions and structure formation around spherical particles with pinned contact lines. Particles attract to apparent contact and organize in near trapped structures that reflect the underlying curvature field. We have derived pair potentials to describe these interactions. The particles distort […]
In the late 1940s, John von Neumann first introduced the concept of self-replication as a way of furthering cellular reproduction research. By the late ‘50s and ’60s this research diverges along two separate paths: cellular automata replication with a focus on biological systems and robotics/machine replication. Generally the work in robotic systems focuses on the […]
Older adults are forming a much larger percentage of the population leading to a strain in the healthcare sector. It is expected that the population aged 65 and over in the United States alone will double in the next 30 years, and similarly worldwide. Despite the abundance of facilities to accommodate the growing older adult […]
Abstract:Â Several chemical processes involve the use of mutually immiscible molecules, for example a water-soluble catalyst is used in combination with oil-soluble reagents to produce water soluble products. There are two possible strategies to run these processes. A mutual solvent can be used to promote mixing of the otherwise immiscible molecules; however, such a system […]
Abstract:Â 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 […]
