BS, Brigham Young University (1992)
Ph.D., University of California, Berkeley (1997)
Runyon-Winchell Postdoctoral Fellow, Harvard University (1998-2000)
Research:
Woolley lab researchers work at the interface between chemistry, engineering, and biology. Thus, Woolley students receive broad technical training and are well-poised to contribute to key research fields, including Micro-and Nanometer-Scale Chemical Manipulation and Analysis. A common theme in Woolley Lab research is the interrelationship between biological molecules and miniaturization. Woolley chemists utilize miniaturization tools to detect and quantify clinically relevant biomolecules and apply DNA in forming nanoscale materials.

3D printed microfluidics for bioanalysis
Research is focused on developing miniaturized analysis systems using 3D printing. Figure 1 shows a schematic diagram of a 3D printed microfluidic design for analysis of preterm birth (PTB) biomarkers from maternal serum. The device combines multiplexed immunoaffinity extraction with solid-phase extraction and fluorescent labeling, followed by rapid electrophoretic separation with fluorescence detection. After a few microliters of unlabeled blood serum are loaded, the device is designed to carry out integrated sample preparation and analysis functions to determine the concentrations of PTB biomarkers, providing risk assessment and enabling improved medical care.

Antimicrobial susceptibility studies using droplet microfluidics
Antimicrobial resistance remains a global threat with ~5 million deaths in 2019 and 10 million annual deaths projected by 2050. Current tools for the analysis of bacteria are slow, leading to delayed diagnosis and treatment. Woolley’s lab is developing methods for rapidly testing antimicrobial resistance using droplet microfluidics, as shown schematically in Figure 2. Research focuses on designing and fabricating microfluidic devices, encapsulating single bacteria with reporter molecules and antibiotics in discrete water-in-oil droplets, and monitoring bacterial growth via fluorescence. Measurements of droplet fluorescence during incubation can elucidate bacterial response to different antibiotic doses, helping to inform potential treatments.

Biotemplated nanofabrication of electronics
The Woolley Lab Group is leading an interdisciplinary team whose objective is to explore bottom-up methods for the fabrication of nanoscale electronic systems. This team folds DNA into controlled nanoscale designs that can be converted into functional electronic elements after purification and metallization (Fig. 3). The Woolley Lab is presently applying these methods in making metal-semiconductor junctions with linewidths as small as 5 nm.
