Ryan C. Bailey

Professor of Chemistry

Professor Bailey received his undergraduate degree in chemistry from Eastern Illinois University in 1999. He then went on Northwestern University, obtaining his Ph.D. in 2004. While at Northwestern, Ryan was the recipient of an American Chemical Society graduate student fellowship. Following a joint post-doctoral fellowship at the California Institute of Technology and the Institute for Systems Biology, he joined the faculty at Illinois in 2006. Prof. Bailey left for the University of Michigan in 2016.


With the sequencing of the human genome, researchers are armed with the fundamental blueprint for human life. It is becoming increasingly clear that the programming architecture which executes the genetic code is tremendously complex and that single biological measurements are incapable of truly describing even the simplest system. To further the understanding of biological processes, hierarchical levels of data (DNA, mRNA, proteins, metabolites) must be measured simultaneously from homogeneous sample populations and in near real-time in response to environmental stimuli. The requirement of measuring large numbers of biological parameters on increasingly small sample sizes is not currently possible given today's diagnostic technology.

As medicine strives to become more personalized and predictive, new technologies are needed to perform high-throughput multiparameter analysis on blood and routinely available pathology samples (e.g. skinny needle biopsies). My group takes an interdisciplinary approach towards developing new bioanalytical tools to understand the onset and progression of disease. Areas of particular interest include cancer metastasis and immunotherapy, which due to tissue heterogeneity and immune cell diversity, represent challenges that necessitate single cell investigation.

We are exploring multi-dimensional surface receptor gradients to stratify heterogeneous tissues, spatially separating cells according to disease state. Once identified, genomic and proteomic analysis of single altered cells will reveal the molecular perturbations responsible for disease progression and differentiation. Single-cell genomic and proteomic characterization, however, is not currently feasible using available analytical approaches. To facilitate these studies, we are currently developing integrated arrays of label-free biological sensors based upon high-Q optical resonators. Features such as high sensitivity and real-time detection enable investigation of dynamic processes such as the temporal secretion patterns of effector molecules from individual T-cells in response to tumor-specific antigen stimulation.

A related long-term goal of the group is the comparative analysis of protein diversity within individual cells. In order for this to be realized in a practical manner, new technologies must be developed that allow for cellular contents to be cataloged in a high-throughput fashion. Promising platforms for these efforts are arrays of metallic nanopores, and we are investigating both the electrokinetic transport and nanoscale plasmonic properties of these materials.
