Research Assistant 2 - Senior Research Assistant

US-OR-Portland

Job ID: 2024-29593
Type: Regular Full-Time
# of Openings: 1
Category: Research
Portland, OR (Waterfront)

Overview

We are developing an exciting new type of cancer diagnostic test that combines microfluidic and microarray technology to pull cancer-derived nanoparticles straight from plasma. Our long-term goal is to bring nanoparticle-based diagnostics to the clinic for the first time. We are currently hiring for a highly motivated and enthusiastic Research Assistant 2 or Senior Research Assistant.

We are looking for applicants with expertise in Engineering or Biology to work in some of the following general areas:

• 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.
• System automation – continuing development and finalization of an automated system to conduct the dielectrophoresis work. The goal is to automate the dielectrophoresis collection protocol to increase sample analysis throughput. This will involve basic robotics and automation programming in LabView.
• 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.
