We focus on understanding, predicting, and controlling emergent behavior in classical systems, often involving colloids.
We use a variety of analytic and numerical approaches.
A complete list of publications can be found on Here is a sample of some recent work.
Engineering hierarchically-structured materials requires breaking natural hierarchies. We show how to do that with pre-assembled building blocks.
Characteristic arrangement patterns determine 'prime real estate' in distributed systems design. But how can patterns be identified?
How do we know if a distributed system design is robust? We show system architectures can be classified by materials-inspired metrics.
Entropy often leads to disorder, but in some circumstances it can promote organization. We determine what those circumstances are.
If we want a material to exhibit a target property, what building blocks do we use to get it? We demonstrate how to do this reverse-engineering in colloidal materials.
To understand chemistry, we think in terms of bonds. But what does a bond require? Does bonding require atoms, electrons, and quantum mechanics?
Entropy is now something we can rationally engineer to make materials organize. How?
Is it possible to design a colloidal material that has a switchablephotonic band gap? We use simulation to show that compressing self-assembled truncated tetrahedra alters structure in a way to shift the band gap.
In designing, e.g., electrical, mechanical, or thermodynamic systems, engineers rely on principles that come from centuries of basic physics investigation. But what are the basic physics principles that guide how to integrate different systems together?
When does matter pack? We find that that for systems of colloids, even when they are found in dense packing structures, they didn't get there by packing.
Solid–solid transitions are ubiquitous in nature and technology, but we still have a lot to learn about them. How can we learn more, and what kind of minimal models can we construct to do so?
How do symmetric, anisotropic objects pack in a spherical container? This simple question is surprisingly difficult to answer, but it has implications for a wide range of physical systems.
Nanoparticle synthesis yields particles that play the role of atoms in nanomaterials, but have properties that can be controlled in ways atoms can't. What does that freedom mean for materials design, and how do we leverage it?
Entropy, especially in the context of anisotropic particle shape, can drive the formation of complex structural order. How does does it do that?
Nanoparticle synthesis inherently yields anisotropically shaped particles. How can we control shape to produce desired bulk behavior?
