Core Responsibilities

Primary Functions

Assist principal investigators and surgeons in preclinical xenotransplant surgeries, including donor organ procurement from genetically engineered pigs, vessel preparation, organ preservation, and intraoperative surgical assistance for pig-to-NHP vascular anastomoses, while maintaining strict sterile technique to minimize infection risk.
Prepare, dose, and administer immunosuppressive and adjunctive pharmacologic regimens (IV, IM, subcutaneous), accurately document administration times and volumes, and monitor pharmacodynamic and pharmacokinetic responses under supervision of veterinary and clinical leads.
Perform perioperative and postoperative clinical monitoring of nonhuman primate and swine subjects including vital signs, telemetry data capture, wound assessments, pain scoring, fluid and nutritional support, and immediate intervention for complications to optimize graft survival and animal welfare.
Collect, label, process, and store biospecimens (blood, serum, plasma, PBMCs, urine, tissue biopsies) according to SOPs and GLP-like documentation, ensuring chain-of-custody with barcoding, cryopreservation (liquid nitrogen), and inventory management for downstream immunologic and molecular analyses.
Execute a wide range of laboratory assays central to xenotransplant research—flow cytometry immunophenotyping, ELISA cytokine panels, qPCR/PCR for viral and gene expression assays (e.g., PERV monitoring), complement activation assays, and basic microbiology when needed—ensuring assay QC and reproducibility.
Process harvested grafts and biopsy samples for histopathology and immunohistochemistry, including fixation, paraffin embedding, microtomy, H&E staining, and targeted IHC markers (CD3, CD20, C4d, macrophage markers), and coordinate slide transfers with veterinary pathologists for blinded scoring.
Maintain and calibrate critical surgical and laboratory equipment such as anesthesia machines, ventilators, surgical instruments, centrifuges, flow cytometers, and refrigerated storage; perform routine preventive maintenance checks and document deviations or failures for timely service.
Support donor genetic and microbiological screening workflows, including PCR-based detection of porcine endogenous retroviruses (PERV), donor genotype confirmation, and pathogen surveillance to ensure safety of xenograft studies and compliance with institutional biosafety standards.
Implement and document aseptic technique, sterile field setup, instrument sterilization, and surgical scrub procedures; oversee autoclave logs and sterility indicators to maintain compliance with IACUC and institutional surgical standards.
Develop, update, and adhere to standard operating procedures (SOPs) for all experimental and animal-care processes, actively participating in protocol refinement, root-cause analysis after adverse events, and implementation of corrective actions.
Accurately record experimental details, surgical notes, anesthesia records, dosing logs, and monitoring observations in electronic lab notebooks (ELN) or study-specific case report forms (CRFs) to support regulatory audits and manuscript preparation.
Coordinate study timelines, animal scheduling, and logistics across multidisciplinary teams including veterinary staff, surgical teams, genetic engineers, and external CROs to ensure on-time completion of preclinical endpoints.
Assist with training and supervision of junior technicians, undergraduate students, and visiting researchers in animal handling, sample processing, sterile technique, and safety practices to maintain team capability and continuity.
Support sample preparation for high-throughput analyses such as single-cell RNA-seq, proteomics, and multiplex immunoassays by performing cell isolation, viability assessments, and quality-control steps required for successful downstream sequencing and analytic workflows.
Execute experimental endpoints including euthanasia per humane guidelines, necropsy with systematic organ inspection, and controlled tissue collection for virology, histology, and molecular assays while maintaining biosafety and humane handling standards.
Maintain inventory and procurement workflows for specialized xenotransplant supplies—sterile surgical kits, organ preservation solutions, custom reagents, anesthetic agents, and PPE—anticipating study needs to minimize downtime due to supply chain delays.
Participate in immunologic monitoring studies: design sample collection timelines with PIs, process PBMCs for functional assays (mixed lymphocyte reactions, cytotoxicity assays), and help analyze trends in anti-donor antibody formation and cellular rejection.
Implement and maintain biosafety and biosecurity practices for work with gene-edited animals and potentially infectious materials, ensuring adherence to BSL2/BSL2+ practices as required and coordinating with institutional biosafety officers.
Contribute to data analysis and visualization for study reports, preparing figures and tables for manuscripts, grant applications, and regulatory submissions; use GraphPad Prism, R, or Python for statistical summaries and graphical representation of survival, immune parameters, and graft function metrics.
Participate in study design meetings and provide practical feedback on feasibility, timeline estimation, and resource allocation for proposed xenotransplant experiments, leveraging hands-on experience to optimize experimental reproducibility and translational relevance.
Maintain high standards of animal welfare and reporting: identify, document, and escalate adverse events, deviations from humane endpoints, and unanticipated outcomes to the veterinary team and PIs to uphold ethical research conduct.
Support validation and transfer of preclinical protocols to contract research organizations (CROs) or clinical translation partners by preparing technical summaries, SOPs, and training modules to ensure consistent study execution across sites.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Assist with preparation of institutional biosafety and IACUC submissions by compiling experimental details, animal numbers, and welfare considerations for protocols and amendments.
Help prepare materials for grant applications, regulatory dossiers, and investigator brochures by providing technical summaries, pilot data, and methods descriptions related to xenotransplant assays.
Represent the laboratory in cross-functional safety meetings, vendor evaluations, and procurement discussions for specialized xenotransplant supplies and equipment.
