- We act BOLDLY—Breakthroughs require pushing the boundaries of science, exploring new frontiers, and thinking differently
- We SUPPORT each other—Respect leads to trust, which leads to excellence
- We work as a CONNECTED team—We must leverage our collective brain power to conquer cancer because no one individual can do it alone
- Development of biological particle separation techniques using dielectrophoresis technology – Using microelectrode array chips to recover cancer-derived nanoparticles from circulation (Gustafson, et al. 2021). This novel work will focus on the development and characterization of new nanoparticle recovery techniques using dielectrophoretic forces. These forces are created by microelectrode array devices that act on the unique dielectric properties of different particles (Ibsen et al. 2017). This work includes increasing particle collection efficiency, understanding the types of particles that are collected and how they can be separated, and developing an internal standard appropriate for different particle types. This position will utilize the high-end specialized dielectrophoresis equipment located here at OHSU. This will also involve quantitative fluorescent microscopy imaging, TEM imaging, immunostaining, and particle characterization.
- Cancer biomarker panel development – Evaluate the nanoparticle associated biomarkers that are collected for their ability to detect pancreatic cancer from plasma samples. Here the goal is to use the developed dielectrophoresis techniques to collect cancer-derived nanoparticles and evaluate their biomarkers for the ability to detect pancreatic cancer.
