Jim Gilchrist's research and scholarly activities are designed to impact both science and engineering through fundamental studies of particulate systems. From an engineering viewpoint, particle technology is ubiquitous, including pharmaceutical, chemical, agricultural, food, cosmetic, ceramic, electronic, and mining processes and in an uncountable number of natural processes including sediment transport in rivers, dune formation, and blood flow. An overarching objective of Gilchrist's research is to develop a better understanding of these far-from-equilibrium particulate processes exhibiting complexity and self-organization.

Gilcrhist manages the Laboratory for Particle Mixing and Self-Organization, where he and his team investigate phenomena ranging from the nano- to macro- scales, typically divided into colloidal and granular systems. Researchers in the lab identify prototypical complex systems for study and develop new experimental, computational, and analytical methods of investigation and analysis. Current projects include suspension transport in chaotic flows, suspension rheology and microstructure, convective deposition, suspension dielectrophoresis, and granular dynamics in vibrated systems. Paired with this fundamental research is collaborative development of applications involving novel processes, materials, and devices such as microfluidic- and industrial-scale mixing and separation, light emitting diode and dye sensitized solar cell coating and internal structure fabrication, fabrication of BioMEMS sensor platforms, and dynamic powder density measurement for online process analysis. The long term goal of this work is to further fundamental understanding of suspensions and granular dynamics and to devise novel ways of controlling these interactions.
