Core Responsibilities

Primary Functions

Coordinate the design and operational execution of xenograft and orthotopic tumor models, partnering with study directors and investigators to ensure study objectives, endpoints, and timelines are achieved.
Perform or supervise tumor cell line preparation and verification, including thawing, culture QC, cell counting, viability assessment, and preparation of inoculum for implantation.
Execute sterile surgical implantation and injection procedures (subcutaneous, orthotopic, intracranial, intravenous) for rodent xenograft models according to SOPs and surgical best practices.
Manage daily tumor measurements using calipers and digital measurement systems, document tumor volume calculations, and flag deviations or humane endpoint triggers to veterinary staff and study leads.
Administer study therapeutics (oral gavage, IV, IP, subcutaneous, topical) with precise dosing schedules, maintain dosing logs, and ensure chain of custody and drug inventory control.
Triage, monitor, and record animal health and welfare, implement humane endpoints, and coordinate veterinary interventions as needed to maintain compliance with animal care standards and IACUC protocols.
Plan and coordinate necropsy and tissue collection workflows, ensuring correct dissection, labeling, fixation, snap-freezing, and chain‑of‑custody for downstream histology, IHC, flow cytometry, PK/PD, and molecular assays.
Maintain meticulous, GLP-compatible study notebooks, electronic records, and sample tracking systems (LIMS), ensuring data integrity, audit readiness, and reproducibility.
Oversee xenograft colony and animal inventory management including ordering, quarantine, genotyping, health surveillance, and vendor communications to prevent study delays.
Implement and update SOPs related to xenograft procedures, aseptic techniques, surgical instruments, and vivarium workflows to ensure consistent, high-quality study execution.
Train and mentor junior technicians and new hires on aseptic technique, tumor measurement methodology, dosing procedures, and humane endpoints to build a robust in vivo team.
Collect and process blood and tissue samples for biomarker, PK/PD, and immunophenotyping analyses, ensuring appropriate storage, labeling, and shipment logistics for CROs and internal labs.
Collaborate with pathology and imaging teams to coordinate tumor imaging (bioluminescence, MRI, CT, ultrasound) schedules and integrate imaging data into study endpoints.
Troubleshoot study deviations, adverse events, and technical complications, perform root-cause analysis, and propose corrective and preventive actions (CAPA).
Support study budgeting, resource forecasting, and scheduling to optimize vivarium utilization and reduce timeline and cost variances for preclinical oncology programs.
Ensure compliance with institutional and national regulations (IACUC, AAALAC, GLP, OSHA) and participate in internal and external inspections, providing documentation and corrective actions as required.
Maintain and calibrate specialized equipment (surgical tools, anesthesia machines, calipers, scales, biosafety cabinets) and coordinate maintenance and repair with facilities teams.
Coordinate sample shipping and biosafety documentation for international and domestic transfers, adhering to IATA, DOT, and institutional biosafety policies.
Generate study reports, data summaries, and operation notes for inclusion in study final reports, presentations, and regulatory submissions, emphasizing clarity and reproducibility.
Partner with cross‑functional teams (drug discovery, bioanalytics, pathology, pharmacology) to align preclinical model selection, endpoint definitions, and translational relevance for drug candidate evaluation.
Drive continuous improvement initiatives to increase study throughput, reduce variability in tumor take rate and growth, and enhance data quality for decision-making in oncology programs.
Manage vendor relationships for cell lines, matrices, specialized diets, and equipment consumables to ensure timely supply and quality control for critical study reagents.

Secondary Functions

Support SOP and protocol authoring and revision for new xenograft model types and specialized surgical techniques.
Assist in biostatistical planning and sample size justification in collaboration with study statisticians to ensure robust experimental design.
Participate in cross‑functional project meetings to provide vivarium timelines, resource needs, and feasibility input on program roadmaps.
Maintain training records, certifications, and continuing education plans for in vivo staff to meet institutional and accreditation requirements.
Contribute to animal facility emergency response planning and continuity of operations for ongoing long‑term studies.
