Description

Application Instructions:

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

POSITION SUMMARY

The Research Assistant III position will focus on managing the lab’s activities in the cryo-electron microscopy (cryo-EM) facility, utilizing high-end equipment for cryo-EM, focused-ion-beam (FIB) milling, and light microscopy, performing computational image processing tasks, assisting users with data collection and analysis, training members of the laboratory, and managing the facility for the laboratory. A central component will be the day-to-day operation and management of the cryo-EM infrastructure, which includes multiple electron microscopes, a FIB milling instrument, a cryo-fluorescence microscope, as well as a number of ancillary equipment associated with cryo-EM. The employee will be the intermediary to the electron microscopy facility for the laboratory and will interact closely with members of the lab as well as the general facility manager for the electron microscopy suite. A second component will be utilizing the equipment, together with computational data analysis infrastructure in the lab, to examine and study the structures macromolecular assemblies. The research work will be performed with some supervision from postdoctoral associates, and there will also be an independent research component. A successful candidate will work part of their time with assisting users, training, etc., as well as dedicate part of their time on independent projects and part of their time on supporting postdoctoral researchers in the lab. The Research Assistant will be expected to apply expertise in the EM field and execute experiments and analyze experimental results independently with limited training in specific techniques and methods. The overall goal of the research is to decipher and understand macromolecular structures isolated from and inside of the native cellular environment.

 

ESSENTIAL FUNCTIONS

(40%) Electron Microscopy Techniques

  • Operate and maintain electron microscopes, including directly interfacing with laboratory members and facility manager
  • Collect cryo-electron microscopy data on the Titan Krios, Talos Arctica, Talos side-entry, F20, and T12 microscopes using automated data acquisition software (Leginon or SerialEM). Data collection will include workflows for both single-particle and tomographic acquisition.
  • Operate FIB milling instrument for cutting into different cell types and preparing lamellae samples for cryo-ET.
  • Operate the cryo-light microscope for helping to prepare samples for CLEM
  • Operate and maintain ancillary equipment, including the Vitrobot, manual blotter, carbon coater, plasma cleaner, etc.
  • Employ various vitrification techniques for freezing cells and to prepare various cellular specimens for FIB milling
  • Sample preparation supporting single particle workflows

(30%) Computational Image Processing Techniques

  • Utilize workflows for single-particle image processing to analyze and process data acquired on the electron microscopes
  • Explore different strategies for computational data analysis of single-particle and/or cryo-ET data, including utilizing different software, analysis schemes, etc.
  • Explore strategies for sub-tomogram averaging
  • Segment tomographic reconstructions and/or train students for segmentation
  • Interpret single-particle cryo-EM and cryo-ET reconstruction data using molecular models
