  • Ability to design, optimize and interpret DMPK-related optimization strategies (discovery testing funnels) as part of a broader research operating plan

  • Technical ability to analyze, interpret and provide context around data describing the ADME, pharmacokinetic and pharmacodynamic properties including use of software such as Phoenix WinNonlin

  • Experience contributing to development and execution of translational pharmacokinetic/pharmacodynamic/efficacy relationships and other useful quantitative pharmacology applications in a discovery setting

  • Strong leadership, interpersonal, communication, problem solving and collaborative qualities to deliver high quality results in a fast-paced environment

 Preferred Experience and Skills

  • Hands-on experience performing translational pharmacokinetic/pharmacodynamic/efficacy and physiologically-based pharmacokinetic (PBPK) software modeling (e.g., Phoenix WinNonlin, Berkeley Madonna, MATLAB).
