• Build and maintain strong networks with key stakeholders and opinion leaders in the relevant regulatory and scientific communities.
• Stay current on scientific and regulatory developments in the focus areas, anticipate emerging expectations, and proactively advise internal stakeholders on implications and options
• Partner closely with regulatory and toxicology project leads to resolve key questions in study design and regulatory interpretation, and to recommend fit-for-purpose paths forward based on a holistic view of risk, timing and requirements.
