A client needs to hire an expert in PBPK modeling to update an existing PBPK/PD model for simulating exposures for workers in Japan. Thus, parameterizing the model for Japanese population and worker scenarios will be required. The results will need to be presented to Japanese government scientists, so being fluent in Japanese and/or experience presenting to Japanese authorities is a plus, but not a requirement. Pay for this project will be determined by your billing rate. It is anticipated that 40-80 hours of work will be required, spread out over several months.
