Title: Senior Scientist, Cryo-ET & Cryo-CLEM Location: Upper East Side Org Unit: General Institutional Cores Work Days: Weekly Hours: 35.00 Exemption Status: Exempt Salary Range: $128,800.00 - $150,400.00 *As required under NYC Human Rights Law Int 1208-2018 - Salary range for this role when Hired for NYC Offices Position Summary The Weill Cornell Medicine Cryo-EM Core is seeking a PhD-level scientist with significant hands-on expertise in cryo-FIB milling and cryo-ET, including data collection and analysis, to serve as the scientific lead for these capabilities within the Cryo-EM Core.

Reporting to the Director of the Cryo-EM Core, the Senior Scientist will play a leading scientific and technical role in commissioning and operating the new instrumentation and establishing an integrated in situ structural biology workflow spanning sample preparation and vitrification, lamella preparation, correlative targeting, tomography data collection on the Titan Krios G5, reconstruction, and subtomogram averaging. The Senior Scientist will have substantial scientific responsibility for developing and advancing the Core’s cryo-ET and cryo-CLEM program, advising investigators on project feasibility and experimental design, developing new methods, training users, supporting operation and utilization of the Titan Krios G5, and supporting projects across Weill Cornell Medicine.

• Job Responsibilities Serve as the scientific lead for cryo-ET, cryo-FIB, and cryo-CLEM workflows within the Cryo-EM Core under the Core Director’s leadership.
• Lead the scientific and technical implementation, commissioning, optimization, and quality control of the Arctis Cryo-PFIB for biological cryo-ET applications, including preparation of high-quality lamellae from cells and tissues.
• Participate in commissioning, operation, and scientific use of the Titan Krios G5, including cryo-ET data collection and other workflows supported by the Core.
• As needed, independently operate the Titan Krios G5 and support investigators with data collection, instrument setup, optimization, troubleshooting, and quality control.
• Establish and optimize integrated cryo-ET and cryo-CLEM workflows, including grid preparation and vitrification, correlative targeting, FIB milling, lamella transfer, Krios data collection, and downstream analysis.
• Work with the Core Director to develop and support tomography data collection on the Titan Krios G5 and Glacios.
• Process and analyze cryo-ET data, including tilt-series alignment, tomogram reconstruction, segmentation, and subtomogram averaging, and assist investigators with data analysis and interpretation.
• Consult with investigators on project feasibility, sample preparation, experimental design, and appropriate workflows for in situ structural biology studies.
• Develop, evaluate, and implement emerging methods and technologies, including automated milling, lift-out approaches, improved correlative workflows, and advances in tomography data collection and analysis.
• Train and mentor investigators, trainees, and Core users in cryo-FIB, cryo-ET, cryo-CLEM, Titan Krios operation, and associated computational workflows.
• Develop and maintain standard operating procedures, training materials, quality-control processes, and other documentation.
• Coordinate scheduling, logs, consumables, and vendor and service relationships associated with cryo-FIB and cryo-ET workflows within the Core’s overall operational structure.
• Work collaboratively with the Core Director and other Core staff to ensure efficient utilization, scientific quality, and integration of instrumentation and workflows across the Cryo-EM Core.
• Participate in scientific outreach, user education, workshops, and other activities designed to expand adoption of cryo-ET and related technologies across WCM.
• Ensure compliance with institutional laboratory safety and operational requirements.
• Education PhD in structural biology, biophysics, cell biology, physics, or a related field.
• Experience Required Qualifications Demonstrated hands-on experience with cryo-FIB milling of biological samples for cryo-ET.
• Hands-on experience with cryo-ET data collection.
• Demonstrated experience with cryo-ET data processing and analysis (for example, IMOD, AreTomo, Warp/M, RELION, Dynamo, or similar), including subtomogram averaging.

Preferred Qualifications

• Experience with plasma-FIB (for example, Arctis), cryo-CLEM, or lift-out.
• Experience in a shared-resource or core facility.
• Familiarity with SerialEM, Tomo5, or PACE-tomo, and scripting in Python or shell.
• Publications involving cryo-ET.
• Knowledge, Skills and Abilities Strong troubleshooting skills with complex vacuum and cryogenic instrumentation.
• Ability to communicate effectively with investigators who have widely varying levels of microscopy experience.
• Licenses and Certifications Working Conditions/Physical Demands The position is based within the Weill Cornell Medicine Cryo-EM Core and includes work in BSL-1/BSL-2 laboratory and office settings.
