2010 Summer Program on Semiparametric Bayesian Inference: Applications in Pharmacokinetics and Pharmacodynamics
Workshop Information
Description of Activities
The program began with a week of tutorials and workshop activities. There were extended, tutorial-style talks during morning sessions, and contributed and invited research talks during the afternoons. Afternoon talks were selected to complement topics covered in the morning sessions.
At the end of the first week workshop research working groups were formed. The working groups tackled particular research problems in the area. Working group activities included workshop-style presentations by group members to stimulate discussion on specific issues. Themes for the working groups and workshop sessions:
- semi-parametric population PK/PD models
- dose individualization
- probability models for PK/PGx networks
- joint inference for PK and PD data
