Evaluate and prioritize the portfolio of projects using objective gating criteria, resource allocation models, and go/no-go decision frameworks to focus investment on the most promising therapeutic or platform opportunities.
Implement robust data governance and scientific reproducibility standards across all laboratories and programs, overseeing SOPs, experimental design, statistical rigor, and independent data review where appropriate.
Lead regulatory strategy and submissions with global perspective, coordinating pre-IND meetings, regulatory briefings, and interactions with FDA/EMA/PMDA to expedite development pathways while maintaining compliance.
Champion translational biomarkers and companion diagnostic strategies to support patient selection, stratification, and clinical endpoint validation in partnership with diagnostic developers and commercial teams.
Oversee budget planning, resource allocation, and vendor management for R&D programs, ensuring cost-effective operations and forecasting to support fundraising and operational planning.
Translate complex scientific findings into clear, compelling narratives for non-scientific executives, board members, and potential partners to drive strategic decisions and business development opportunities.
Establish and monitor key performance indicators (KPIs) for scientific programs, including milestone achievement, IND/CTA timelines, data readouts, and external validation metrics to ensure accountability and transparency.
Integrate emerging technologies—such as AI/ML-enabled drug discovery, high-throughput screening, single-cell biology, gene editing, and advanced analytics—into the R&D strategy to accelerate discovery and optimize pipelines.
Ensure compliance with ethical, safety, and regulatory standards for laboratory operations, human subject research, animal welfare, and biosafety across all teams and external partners.
Mentor and cultivate a culture of scientific excellence, collaboration, and continuous learning that attracts top scientific talent and supports high retention in competitive markets.
Lead crisis and risk management for scientific programs, including safety events, clinical holds, or unexpected preclinical failures, by rapidly mobilizing cross-functional response teams and contingency plans.
Advise and partner with commercial, legal, and finance leadership to align scientific development timelines with market access, pricing, payer strategy, and product launch readiness.
Build and maintain a Scientific Advisory Board (SAB) and external expert network to provide independent review, validation, and guidance on strategic scientific decisions and program prioritization.
Drive translational and publication strategy, including peer-reviewed manuscripts, conference presentations, and data disclosure policies that maximize scientific visibility while protecting company IP and competitive advantage.
