Building Biologist Jobs in Oregon (NOW HIRING)

Department Overview

This posting is for a Post-Doctoral Research Fellowship focused on the structure and function of membrane proteins, with an emphasis on ligand-gated ion channels. The successful candidate will contribute to studies aimed at understanding the molecular mechanisms underlying ion channel function, gating, and pharmacology through an integrated combination of biochemical, functional, and structural approaches.

The Mansoor Lab studies the molecular structure and function of ion channels and receptors, with the broader goal of understanding fundamental mechanisms of membrane protein function and leveraging these insights toward the development of novel pharmacological approaches. Typical techniques and experiments in the lab include, but are not limited to, molecular biology, mammalian tissue culture, heterologous protein expression, membrane protein expression and purification, electrophysiology, and high-resolution structural biology. Applicants should have prior experience with protein expression and purification and be comfortable working with membrane proteins for structure-function studies. Experience with mammalian tissue culture and heterologous mammalian expression systems is highly desirable. Experience studying ligand-gated ion channels, including familiarity with two-electrode voltage clamp (TEVC) and/or whole-cell patch-clamp electrophysiology, is also desirable. Previous experience with high-resolution structural biology techniques, such as X-ray crystallography and/or single-particle cryo-electron microscopy, is preferred.

Function/Duties of Position

• Assist the PI with manuscript preparation and grant applications.
• Present, or assist in the presentation of, research projects at retreats, seminars, conferences and other OHSU or public venues.
• Providing training to users on lab practices and protocols, including sample preparation and instrumentation use.
• Maintain an accurate and detailed laboratory notebook of all experiments performed. Participate in lab meeting.
• Training of lab personnel and supervision of Research Assistants, students and other lab members.
• Perform routine lab operations, including but not limited to the purchase of laboratory supplies, monitoring supplies and maintaining all laboratory equipment.
• Other duties as assigned.
