  • Assist in training users on routine techniques and laboratory equipment.

  • Perform whole animal fixation and tissue dissection of fish and rodents.

  • Section, using vibratomes and cryostats, fixed and fresh-frozen tissue for histological experiments.

  • Mount, stain, and cover tissue sections on microscope slides.

  • Assist team members with techniques that require changing solutions at defined intervals.

  • Perform standard tissue labeling techniques (e.g. H&E, silver stain, DAPI, etc).

  • Perform immuno-histochemistry (IHC), in-situ hybridizations, or other labeling techniques on tissue sections.

  • Assist with tissue clearing on whole mount specimens.

  • Maintain detailed documentation of work performed.

  • Read and follow established protocols. Assist in the optimization of protocols for new techniques and tissue types.

What you bring:

  • Bachelors degree (Masters preferred) in Cell Biology, Molecular Biology, Biochemistry, or other life science or HT (ASCP) certification. (An equivalent combination of education and relevant work experience will be considered.)

  • 4 years of related laboratory experience.

  • Preferred experience working in a shared resource or core facility.

  • Demonstrated proficiency in the preparation of buffers and solutions.

  • Demonstrated proficiency in the use of a vibratome and cryostat.

  • Experience handling fish and rodents.

  • Experience trouble-shooting protocols.

  • Some experience as a project lead or point of contact.

  • Ability to interact with collaborators at all levels, including senior scientific management, project scientists, Janelia lab heads, visitors (domestic and international), and scientific support staff.

  • Strong communication skills to update team members, supervisors, and researchers on the status of projects and work in progress.

  • Proven ability to work within time constraints to achieve experimental results.

  • Strong time management skills.
