Core Responsibilities

Primary Functions

Plan, design and execute complex preclinical xenotransplantation experiments using porcine-to-primate and rodent xenograft models, including development of study protocols, surgical coordination, perioperative care and objective graft survival endpoints to support translational drug/device strategies.
Lead immunophenotyping workflows by performing high-dimensional flow cytometry panels, compensation, gating strategies and data analysis to quantify innate and adaptive immune responses to xenografts and genetically modified donor tissues.
Develop and run quantitative humoral immunity assays (ELISA, Luminex, xMAP) and functional neutralization/complement activation assays to measure anti-pig antibody titers, IgG/IgM subclasses and xeno-reactive complement pathways over defined study timepoints.
Execute tissue processing, histopathology, immunohistochemistry (IHC) and digital slide analysis to assess graft architecture, rejection signatures, cell infiltration, complement deposition and marker co-localization in xenograft specimens.
Collaborate with veterinary surgeons to perform or support aseptic transplant surgeries on large animal models (porcine, non-human primate) and small animal xenotransplant procedures, ensuring consistent surgical technique, anesthesia protocols and humane endpoints.
Apply molecular biology techniques (RT-qPCR, droplet digital PCR, bulk RNA-seq and targeted gene expression panels) to quantify donor and recipient transcriptomic changes associated with rejection, tolerance, and immunomodulation.
Design and perform CRISPR/Cas9 and gene-editing validation assays to characterize donor organ modifications (knockouts, knockins, human transgene expression) and evaluate their effects on immunogenicity and complement sensitivity.
Maintain GLP/GMP awareness and contribute to generation of GLP-compliant raw data, study notebooks (ELN), SOPs, and QC documentation to enable regulatory submissions such as IND/IDE packages and veterinary review dossiers.
Build, maintain and curate study datasets in LIMS and research databases, perform quality control, and prepare analysis-ready data for statistical modeling and visualization using R, Python or GraphPad Prism.
Produce comprehensive study reports, technical memoranda and regulatory-ready summaries that clearly document methods, results, interpretation and next-step recommendations for cross-functional stakeholders and external regulators.
Coordinate and manage outsourced laboratory services and external CRO relationships (e.g., specialized histopathology, viral testing, bioanalysis), including protocol transfer, sample shipment logistics, and data reconciliation.
Implement and optimize ex vivo and in vitro xenoreactivity assays (mixed lymphocyte reactions, cytotoxicity assays, cellular proliferation assays) to phenotype cellular drivers of rejection and to test candidate immunomodulatory strategies.
Design and execute pharmacodynamic and pharmacokinetic sampling plans for biologic immunosuppressants used in xenotransplant studies, including assay validation and interpretation of biomarker dynamics in preclinical species.
Lead troubleshooting, root-cause analysis and continuous improvement of laboratory workflows, instrument performance (flow cytometers, sequencers, imaging platforms) and sample processing pipelines to improve reproducibility and throughput.
Mentor and train junior technicians and research assistants on animal handling, aseptic technique, tissue harvest, assay execution, data entry and GLP documentation to uphold study quality and regulatory readiness.
Integrate single-cell and bulk omics data with immunophenotyping and histology to generate mechanistic insights into rejection pathways and to support biomarker discovery for translational endpoints.
Participate in cross-functional project meetings, contribute to project plans, timelines and budgets, and communicate study risks, milestones and resource needs to program leadership.
Prepare materials and present experimental findings internally and at scientific conferences or regulatory meetings, translating complex preclinical data into clear narratives for nontechnical stakeholders.
Support grant and IND/IDE writing by contributing experimental design sections, methods, preliminary data summaries and responses to regulatory reviewer questions related to xenotransplantation safety and efficacy.
Maintain compliance with institutional animal care and use committee (IACUC), biosafety (IBC) and other regulatory requirements for xenotransplantation work, including pathogen screening, xenogeneic risk mitigation and documentation of animal health monitoring.
Stay current with the scientific literature, patent landscape, and regulatory guidance related to xenotransplantation, porcine endogenous retrovirus (PERV) testing, and novel immunomodulatory approaches, and integrate insights into study designs.

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 inventory management, reagent QC, and procurement for critical xenotransplant assays and surgical supplies.
Support internal audits, quality assurance activities and corrective action plans related to preclinical study conduct and recordkeeping.
