The Research Assistant II will be responsible for, under the supervision of a postdoctoral associate, research support and some lab management duties in support of the Principal Investigator's (PI) studies. Research duties will involve performing techniques in molecular biology and biochemistry such as production and purification of nucleic acids, proteins, and nucleoprotein complexes. Scientific research duties will also include performing biochemical assays in support of research projects as well as assisting the postdoctoral associates with experimental design and direction of future experiments. This position will also involve assisting in hiring new staff as well as leading and assisting with training of junior lab staff (junior technicians, students and volunteers) as necessary. The position provides opportunities for some independence in defining the directions of the project, under general guidance by a postdoctoral associate and principal investigator. This position will provide in depth knowledge and expertise in biochemical techniques, including routine to moderately advanced methods, and procedures on new assignments in support of research directions. The incumbent is also responsible for assisting with maintaining lab materials including FPLC columns, plasmid DNA, DNA and custom primer data, inventory lists, and freezer/fridge contents, ordering, equipment upkeep and repair, ensuring compliance with all Salk policies, and working with collaborators to achieve specific research goals.
