• CMC Support: Author and review relevant sections of IND/NDA/ANDA filings, ensuring technical data accurately reflects the validated state of the QC laboratory.
  
  

Operational Leadership & Team Development

• Hands-On Leadership: Work in close collaboration with QC analysts, microbiologists, and cross-site SMEs to ensure adequate bench support, redundancy, and coverage for release testing and troubleshooting while the QC Team is being built.
• SME Management: Mentor a diverse team of subject matter experts, fostering a culture of technical excellence and collaborative problem-solving between the analytical and micro sub-departments.
• Resource Planning: Develop and manage the QC department budget, including capital expenditure on lab buildouts and the procurement of reagents and reference standards.
• KPI Tracking: Establish and monitor departmental metrics (e.g., sample turnaround time, lab error rates) to ensure the QC lab meets the operational demands of the production schedule.
  
  

Laboratory Informatics (CDS/LIMS)

• Serve as business owner for Waters Empower chromatography data system (CDS), including user administration, system suitability configuration, and integration with QC workflows.
• Lead the configuration and implementation of Waters NuGenesis LMS for sample management, stability pulls, and data review/approval, ensuring alignment with data integrity requirements.
• Partner with IT and vendors to qualify, maintain, and continuously improve the CDS and LIMS environments.
