• Perform non-compartmental (NCA) and compartmental PK analysis, PK/PD modeling, and translational pharmacokinetics to guide compound optimization and dosing strategies.

• Author and review technical reports, regulatory submissions (INDs, NDAs, BLAs), and scientific publications.

• Collaborate closely with toxicology, clinical pharmacology, CMC, and discovery teams to ensure suitable study design and robust PK/PD understanding of drug candidates.

• Leveraging specialized ADME/PK skills such as in vitro ADME, in vivo ADME, biotransformation, PK/PD, or physiologically-based pharmacokinetic modeling (PBPK) to impact project progression and decision-making

• Manage external CROs for bioanalytical and PK studies, ensuring data quality and regulatory compliance (GLP/GCP).

• Mentor junior scientists and contribute to departmental initiatives to enhance scientific and operational excellence.

• Capable of independently troubleshooting and resolving Sciex LC-MS/MS challenges as they arise in the lab.

• Deep expertise in LC-MS/MS, Orbitrap, Q-TOF and HPLC methods.

• Strong background in PK modeling (WinNonlin, Phoenix, NONMEM, R, etc.) and interpretation of PK/PD data.

• Experience with regulatory submissions (FDA/EMA/ICH guidelines) and working in a GLP/GCP environment.

• Proven leadership skills with the ability to influence cross-functional teams and mentor junior scientists.

• Excellent communication, problem-solving, and project management abilities.

• Familiarity with DMPK principles (metabolism, transporters, drug-drug interactions).

• Knowledge of automation and high-throughput bioanalytical techniques.
