Department Overview

We are seeking a talented, motivated and highly interactive individual to work in a multidisciplinary team at OHSU as part of the Multiscale Microscopy Core (MMC).  Included at this OHSU Electron Microscopy Core are two Transmission Electron Microscopes (TEM), a Tecnai T12 Biotwin, and a Glacios cryoTEM microscope (outfitted with a K3 direct electron detector). This facility also has a Helios G3 FIB-SEM, a newly installed Helios UC5 FIB-SEM equipped with Oxford EDS detector and Leica cryo stage, a Teneo SBF-SEM and a CorrSight for correlative light and EM projects.


The Associate Core Scientist will provide support to the MMC’s activities and core director by communication with core facility users, providing sample preparation, imaging acquisition and training to new users and junior staff. The candidate will also be involved in laboratory maintenance including consumables and reagents restocking, operations with advanced electron microscope equipment (TEM, cryoTEM, SEM, FIB-SEM and SBF-SEM) and provide assistance with organization of laboratory events including training and workshops.  The candidate will provide administrative support of laboratory operations including iLabs, ordering, maintenance of records and inventory databases and liaising with the manufacturers and vendors for purchases, repairs, upgrades and application support.  It is expected for this candidate maintain current knowledge with literature and database searches on topics relevant to the projects, methodology and instrumentations of the core.
