Justine first came to the NIH as a postbacclaureate IRTA after graduating from Rennselaer Polytechnic Institute with a B.S. in biomedical engineering in 2010. As an undergraduate at RPI, she worked to optimize 3-D cell printing technology for vascular tissue engineering applications. In 2008, Justine worked as a summer intern at the University of Minnesota to develop a real-time, label-free biosensor that measured DNA hybridization kinetics. This work led her to spend her subsequent summer in 2009 at the National Institute of Material Science in Tsukuba, Japan to optimize field-effect devices capable of detecting DNA hybridization by taking potentiometric measurements of the density of the intrinsic negative charge of DNA in the sample. With her experience in microfluidics and microfabrication, Justine is now a contractor at the NIBIB developing and characterizing microfluidic devices for collaborators within the NIH.
