A PBPK (Physiologically Based Pharmacokinetic) Modeling job involves developing mathematical models to predict the absorption, distribution, metabolism, and excretion (ADME) of drugs in the human body. Professionals in this role use computational tools to integrate physiological, biochemical, and drug-specific data to support drug development, dose optimization, and regulatory submissions. PBPK modelers work in pharmaceutical companies, regulatory agencies, and research institutions to improve drug safety and efficacy predictions. Strong expertise in pharmacokinetics, coding (e.g., MATLAB, R, Python), and data analysis is essential for this role.
