Lead clinical dosimetry strategy across Alpha-9’s radiopharmaceutical programs, defining standards for absorbed dose calculation, time-activity modeling, and interpretation across early-phase clinical studies.
Establish and govern quantitative imaging standards for SPECT/CT and PET/CT, including acquisition protocols, reconstruction parameters, QC frameworks, and site qualification criteria.
Serve as the internal authority on dosimetry, translating patient- and program-level dose data into actionable insights that inform dose escalation, safety evaluation, and clinical decision-making.
Integrate dosimetry into clinical trial design and regulatory submissions, including protocols, amendments, investigator brochures, clinical study reports, and IND/CTA documentation.
Partner closely with Clinical Development, Clinical Pharmacology, Biostatistics, and Clinical Operations to ensure dosimetry is embedded in dose selection strategy and study execution.
Manage external imaging and dosimetry vendors and core laboratories, ensuring methodological consistency, data quality, and timely delivery across active programs.
Support regulatory interactions and scientific communications, including responses to agencies, investigator meetings, abstracts, manuscripts, and conference presentations.
The Skills You Bring
PhD or MS in Medical Physics, Radiation Physics, Nuclear Medicine Physics, or related discipline (Ph.D. preferred).
6–10+ years of experience in radiopharmaceutical development, molecular imaging, or medical physics within oncology drug development.
Direct experience in radiopharmaceutical or radioligand therapy clinical programs required.
Proven experience with quantitative SPECT/CT and PET/CT imaging workflows in clinical trial settings.
Strong understanding of internal dosimetry principles (e.g., MIRD methodology) and organ/tumor absorbed dose modeling.
Experience contributing to or supporting IND/CTA submissions and regulatory interactions involving imaging or dosimetry.
Demonstrated ability to translate quantitative radiopharmaceutical data into clinical development decisions.
Experience operating in cross-functional drug development teams, ideally across multiple concurrent clinical programs.
Experience influencing or contributing to dosimetry methodology, standards, or decision frameworks in clinical development preferred.
