Operate and maintain common lab instrumentation: biosafety cabinets, CO2 incubators, refrigerated centrifuges, microplate readers, thermocyclers, spectrophotometers, and automated liquid handlers, including routine calibration logs and troubleshooting.
Implement and document aseptic technique, waste segregation, and hazardous material handling (chemical, biological, and genetically modified organisms) in compliance with institutional biosafety committee (IBC) approvals and relevant regulations.
Maintain inventory management systems and LIMS entries for reagents, consumables, biological stocks, and experimental samples; place reagent orders and perform lot reconciliation to ensure experimental continuity.
Prepare media, buffers, and specialized growth substrates (including xenobiotic-compatible media), perform sterility testing, and document batch records and deviations following GMP/GLP where applicable.
Assist in high-throughput screening assays and robotics workflows, including plate setup, liquid handling programming, sample indexing, and preliminary data QC to ensure throughput targets and assay fidelity.
Perform microscopy and imaging support tasks: fluorescence microscopy, live-cell imaging setup, slide preparation, and basic image acquisition for downstream analysis by senior staff.
Conduct flow cytometry sample preparation, staining, compensation controls, and coordinated acquisition with core flow cytometry facilities; assist with data export and metadata annotation.
Execute environmental monitoring and decontamination protocols in the xenobiology suite, including surface swabs, incubator cleaning, HEPA filter checks, and documentation of corrective actions.
Implement sample tracking and chain-of-custody procedures for sensitive or regulated samples, ensuring appropriate labeling, secure storage, and proper transfer documentation for internal or external collaborators.
Support design-of-experiments (DOE) under guidance: set up experimental matrices, randomization, replicate structure, and accurate recording of experimental conditions and deviations in electronic lab notebooks (ELNs).
Process and prepare biological samples for mass spectrometry, HPLC, or metabolomics workflows, including extraction, derivatization, and QC steps for reliable downstream analysis.
Participate in protocol development and SOP updates by providing hands-on feedback, performing validation runs, and documenting performance metrics and change control records.
Assist with safety trainings, onboarding of new lab personnel, and demonstrate best practices for biosafety, chemical safety, and waste handling; ensure new staff are competent in xenobiology-specific procedures.
Liaise with cross-functional teams (bioinformatics, regulatory, facilities, procurement) to coordinate experiments, equipment requests, and compliance documentation that enable translational research milestones.
Collect and curate experimental metadata, maintain project-specific ELNs and shared documentation repositories, and prepare preliminary methods or materials sections for internal reports and grant documentation.
Troubleshoot routine experimental failures and escalate complex technical issues to senior scientists; document corrective and preventive actions (CAPA) and lessons learned for process improvement.
Support pilot-scale cultivation and small-batch process development tasks, including media optimization, growth kinetics sampling, and preliminary scale-up parameter documentation to inform process scientists.

Secondary Functions
