- Develop and apply modeling frameworks to prioritize targets, optimize drug properties, and inform clinical trial design.
- Engage with external partners and internal stakeholders to align modeling objectives with therapeutic strategy and guide internal strategy.
- Present modeling results in a clear and impactful way to cross-functional teams, collaborators, and senior leadership.
- Beta test and benchmark FL104’s software to identify and prioritize opportunities to improve performance and user experience and provide feedback to AI researchers and engineers.
Qualifications
- PhD. in systems pharmacology, bioengineering, applied mathematics, or a related field, with 12+ years of industry experience.
- Proven track record in developing and applying mechanistic models in translational or clinical contexts.
- Expertise in QSP, PK/PD modeling, and simulation tools such as MATLAB, Monolix, SimBiology, or Julia.
- Experience managing alliances with multi-disciplinary teams in pharma, biotech, or academic translational research settings.
- Strong communication skills and the ability to translate complex models into actionable insights for diverse stakeholders.
Preferred Qualifications
- Experience contributing to IND-enabling or clinical development programs and leading computational modeling within programs.
- Background in immunology, oncology, or metabolic disease is a plus.
- Experience building and simulating mechanistic models in Python environments.
- Familiarity with hybrid modeling approaches that combine mechanistic models and machine learning.
- Experience with Git, AWS, and collaborating on software projects.
