Highlights of research activities
My research is focused on DNA nanotechnology, including colloidal self-assembly and designed chemical reaction networks. I have integrated this technology with my knowledge and experience in laser fluorescence detection and microfluidics. I have programmed lab automation and data analysis including image analysis in Mathematica, MATLAB and LabView. My research interests include the expansion of DNA-directed self-assembly to include biocompatible materials with designed, self-assembled sub-structures to influence and engineer tissue growth.
Under Daniel Chiu at the University of Washington in the Department of Chemistry, I studied microfabrication of microfluidic devices for biological analyses. This culminated in the use of capillary electrophoresis for the chemical analysis of the contents of single 100 nm diameter vesicles and single mitochondria. The ability to use sensitive fluorescence detection for precise, small volume analyses remains a strong interest that is being expanded in the Allen lab.
In Andrew Ellington’s lab at the University of Texas, I studied the design and application of DNA reaction networks. This included paper-based assays for the detection of isothermally amplified DNA, theoretical and experimental studies of chemical localization in macro-scale gels by DNA sequence, and the self-assembly of colloidal gels based on DNA “smart glue.” This final project is the foundation for future materials-based research in the Allen lab.
My research at the University of Idaho integrated Aptamers, microparticle synthesis, and chemical sensing using DNA nanotechnology. My students and I seleced aptamers against several disease-relevant proteins, Drosophila melanogaster virus particles, and against light-up dyes.
Research and Professional Experience:
Biotech startup company Senior Scientist
6/2020 – current
I work for a biotech company in the Seattle area.
University of Idaho Assistant Professor, Chemistry
1/15 – 5/2020
I served as an assistant professor of chemistry in the analytical division at the University of Idaho. My research focussed on DNA aptamers-based biosensors. This includes DNA nanotechnology-based sensors and a generation of hydrogel colloids for surface-immobilized amplification.
University of Texas Postdoctoral Fellow, Chemistry/ICMB
9/09 – 12/14
I was a postdoctoral fellow under Andrew D. Ellington. My research is in self-assembly mediated by DNA nanotechnology and computation. The other side of my research is to apply DNA reactions to the detection of nucleic acid analytes and integrated the result into a paper-fluidic detector for point-of-care diagnosis.
University of Washington Research Assistant, Chemistry
6/01 – 8/09
I wrote my dissertation under Prof. Daniel T. Chiu on the use of microfluidics in analyzing small, biological samples in vitro and in vivo. For the capstone, I analyzed single, 100 nm synthetic vesicles (1 attoliter volume) and single mitochondria with capillary electrophoresis and laser induced fluorescence. I led six projects to completed publications and mentored two undergraduate students.
University of Washington Teaching Assistant, Chemistry
4/08 – 6/08
Taught introductory organic chemistry laboratory under Prof. Michael Gelb. I was responsible for laboratory safety, instruction on experimental protocol, and grading. My philosophy of teaching is to seek first to understand, then to be understood. Many confusions can be cleared if the instructor takes the time to understand them.
