Research

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 this Google Scholar page. Here is a sample of some recent work.

Packing and Structure

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.

Check out our paper in PNAS.

Systems Physics

In designing, e.g., electrical, mechanical, or thermodynamic systems engineers have principles that come from centuries of basics physics investigation to rely on. But what are the basic physics principles that guide how to integrate different systems together?

Check out our paper on the arXiv.

Solid–Solid Transitions

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?

Check out our paper in PNAS.

Packing in Confinement

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.

Check out our paper in PNAS.

Digital Alchemy

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?

Check out our paper in ACS Nano.

Shape Entropy

Entropy, especially in the context of anisotropic particle shape, can drive the formation of complex structural order. How does does it do that?

Check out our paper in PNAS.

Entropically Patchy Particles

Nanoparticle synthesis inherently yields anisotropically shaped particles. How can we control shape to produce desired bulk behavior?

Check out our paper in ACS Nano.
