Dr Kelly currently serves as lead of the microfabrication facility in the Environmental Molecular Sciences Laboratory at Pacific Northwest National Laboratory (PNNL). He has a broad background in the design and fabrication of microfluidic devices and other microsystems for a diverse array of applications. His prior research focused on the development of novel separation and analysis methods for proteins and peptides within microfluidic devices. He also developed new fabrication methods for creating microdevices in plastic substrates and interfacing microchannels with semipermeable membranes. While at PNNL, Dr. Kelly developed approaches for increasing the sensitivity of electrospray ionization mass spectrometry using both capillary based and microfabricated electrospray sources. His current interests involve coupling microfluidic systems with mass spectrometry for single cell and other sample-limited bioanalyses.
