2026 SNMMI Annual Meeting

Mirjam, a pharmacometrics consultant, serves as the US Lead for Pharmacometrics, Division II, at Certara. With expertise spanning various modalities, including complex biologics, she specializes in Cell and Gene Therapy.

Hunter Stephens, PhD, is an Associate Director in the Pharmacometrics group at Certara. He specializes in applying mathematical and computational models to understand the pharmacokinetics and pharmacodynamics of drugs, especially radiopharmaceuticals. He has a PhD in Medical Physics from Duke University. He also holds an MS in Physics from North Carolina State University and a BS in Mathematics from Tennessee Tech University. His work in TRT has focused on building semi-mechanistic population PK models to simulate and predict absorbed and biologically effective doses to inform dose-range finding and questions of safety and efficacy. In addition, he has extensive experience in radiation dosimetry from external and internal sources.

Joshuaine Grant is a Senior Director in Quantitative Systems Pharmacology at Certara with more than 25 years of experience integrating biophysics, disease biology, and quantitative modeling to advance drug development. She leads collaborative projects that use mechanistic and translational QSP modeling to inform key decisions from discovery through the clinic. Her broad experience across biologics and complex therapeutics has supported Certara’s growing leadership in radioligand and targeted radiotherapies.
