Colloids and Interfaces, Transport in porous/nonporous materials, Single-molecule microscopy, Separations, Biomolecules at interfaces, Surface modification by self-assembly, Heterogeneous Catalysis/Biocatalysis, Biomaterials.

Molecular Transport at Interfaces

The dynamic behavior of molecules and nanoparticles at interfaces leads to complex phenomena, where heterogeneity may arise from spatial variation of the interface itself, from molecular structures, or through inhomogeneous dynamic behavior. To obtain relevant information about these complex dynamics, we have developed highly multiplexed single-molecule/single-particle tracking methods that acquire large numbers of trajectories permitting rigorous analysis using statistical modeling and machine learning. A specific discovery that was enabled by these methods involves the ubiquitous intermittent motion (i.e. “hopping diffusion”) of molecules at interfaces, which was explicitly confirmed using 3D double-helix point spread function imaging. Ongoing research studies the impacts of interfacial dynamics on various technological applications, membrane biophysics, and separations processes.

Transport in Porous and Complex Materials

Work in our lab has explored the motion of Brownian, pressure-driven, and self-propelled molecules, polymers, and nanoparticles within highly interconnected porous environments (both static and dynamic), leading to insights linking microscopic pore-scale mechanisms to macroscopic transport. Ongoing research includes fundamental studies of mass transport in complex interface-rich environments and within nominally non-porous materials, as well as more applied studies of phenomena in porous filtration and separations media that are relevant to energy and pharmaceutical technologies.

Biomolecules at Interfaces

Biomacromolecules, like proteins and DNA, interact in complex ways at interfaces and within interface-rich materials. We are studying the structural changes that occur when proteins and oligonucleotides adsorb or are immobilized at solid surfaces and at the air/water interface using single-molecule tracking fluorescence microscopy and other tools. We are particularly interested in understanding how surface-mediated structural changes (e.g. protein unfolding and refolding) influence applications including biosensing, biocatalysis, biomaterials, pharmaceuticals, and vaccines.

Catalyst Surface Modification using Self-assembled Monolayers

Self-assembled monolayers (SAMs) represent a versatile coating technology with applications in biocompatibility, nanotechnology, biosensors, corrosion resistance, and molecular electronics. We study the growth and structure of SAMs, ultra-thin molecular films adsorbed from solution on solid surfaces, and we are particularly interested in the use of SAMs to modify heterogeneous catalysts, to control activity and selectivity in thermal, biphasic, and electrochemical reactions.
