About the Role:
Biogen is seeking a highly motivated and experienced Principal Scientist specializing in biotransformation/metabolite identification to join the Drug Metabolism and Pharmacokinetics (DMPK) department. This role is ideal for a technically strong scientist who thrives in a hands-on laboratory environment and enjoys solving complex drug metabolism challenges. The successful candidate will design and execute studies to identify and characterize drug metabolites, oversee some outsourced work, and deliver high-quality data to support drug discovery and development programs. Excellent communication and interpersonal skills are required, along with scientific thinking and problem-solving skills.
What You’ll Do:
- Design, execute, and interpret biotransformation studies to characterize drug metabolites in vitro and in vivo.
- Conduct hands-on laboratory work, including sample preparation, LC-MS/MS, and high-resolution mass spectrometry (HRMS) for metabolite profiling.
- Oversee and manage outsourced studies with CROs, ensuring scientific quality and compliance with project timelines.
- Provide detailed interpretation of metabolite data to guide medicinal chemistry and safety assessment decisions.
- Maintain awareness of regulatory guidance (e.g., FDA, EMA) and scientific trends in biotransformation and MIST (Metabolites in Safety Testing).
- Design and oversee mass balance and metabolite identification studies using ³H- or ¹⁴C-radiolabeled compounds in in-vitro systems and preclinical species for development candidates. Provide scientific guidance on metabolite identification in clinical SAD/MAD studies and support metabolism-related activities required for regulatory submissions.
- Develop, optimize, and validate innovative analytical methods to improve biotransformation workflows.
- Author and review high-quality scientific reports, regulatory submissions, and presentations.
- Collaborate effectively with cross-functional teams, including bioanalytical, toxicology and medicinal chemistry.
Who You Are:
Qualifications:
- Ph.D., Master’s, or Bachelor’s degree in Chemistry, Biochemistry, Pharmaceutical Sciences, or a related discipline, with 5+ years of relevant industry experience. (Master’s with 8+ years OR Bachelor’s with 10+ years)
- Strong expertise in drug metabolism and biotransformation, with hands-on experience in metabolite identification using LC-MS/MS and HRMS.
- Knowledge of in vitro models (hepatocytes, microsomes, S9 fractions) and in vivo systems for drug metabolism studies.
- Ability to analyze complex data and provide actionable insights.
- Familiarity with regulatory guidelines for metabolite safety testing (MIST).
- Excellent communication and documentation skills, with the ability to work independently and collaboratively.
Preferred Skills:
- Experience with human ADME studies, including QWBA (Quantitative Whole-Body Autoradiography) and radiolabeled compound studies.
- Familiarity with oligonucleotide biotransformation
- Track record of peer-reviewed publications or conference presentations in drug metabolism or biotransformation.
- Strong project management skills for coordinating outsourced studies.
