Job Description

Application Instructions:

Employment History Include your last ten (10) years of employment history, or length of your employment history if less, including all positions (even those that are not relevant to this position) and periods of unemployment. Incomplete information could disqualify you from further consideration.


Research Assistant II position will focus on project that involve extensive tissue culture with cancer cell line models, molecular biology, and laboratory organization. A successful candidate will work half of their time on independent projects and the other half on supporting students/postdoctoral researchers in the lab by maintaining laboratory stocks, keeping supplies and reagents organized, and helping with orders/purchasing. The position will be responsible for establishing and utilizing cancer cell line models and performing biochemical assays like western blotting as well as flow cytometry-based assays, and some microscopy. Position will be trained in specific techniques and methods in order to execute experiments that are broadly designed by post doc or PI and must be able to carry out and analyze experimental results independently. The overall goal of the research is to understand how cancer cells utilize alternative processes to adapt with metabolic recycling pathways, like autophagy, are blocked.
