Cash Lab Assistant Project Scientist

The Department of Molecular and Cellular Biology at the University of California, Davis invites applications for one Assistant Project Scientist in the biochemistry and structural biology lab of Dr. Jennifer Cash.

The Project Scientist makes significant and creative contributions to a research or creative project in their academic discipline. The appointee possesses the subject matter expertise and the creative energy necessary to function at a high level of competence. The appointee will participate in activities to increase, improve, or upgrade competency. Appointees with Project Scientist titles may engage in University and public service. They do not have teaching responsibilities. Although the Project Scientist is expected to work independently under the general guidance of an academic member with an independent research program, they are not
required to develop an independent research program or reputation. They will carry out research or creative programs with supervision by an individual in an academic title that carries with it automatic Principal Investigator status. The Project Scientist does not usually serve as a Principal Investigator but may do so by exception.

Position Description:

Research (80%)
