- Coordinate handoff of trimmed tissues, cassettes, containers, exceptions, urgency notes, and retrim requests to Histology.

- Assist in reviewing raw data and technical activities and preparing responses to Quality Assurance (QA) findings.
- Perform Necropsy Technician duties as assigned, including support for table readiness, specimen collection, labeling, and downstream handoffs, with tissue trimming as the primary responsibility.
- Review the daily trimming queue with Necropsy and Histology partners to align priorities, anticipated volume, special handling needs, and time-sensitive study requirements.
- Perform other related duties as required.
Interpersonal:
- Communicate priorities, risks, and handoff requirements clearly and collaborate professionally across Pathology and related departments.
Technical Consultation & Capability Development:
- Provide role-specific input to study planning and workflow improvement; escalate technical or operational questions to the appropriate supervisor or functional leader.

- Ability to lead daily work, train staff, follow SOPs/protocols, and maintain accurate controlled records.
