Community

A cornerstone of our philosophy is that we support the pharmacometrics community as much as possible, with volunteer participation in activities and open-source tool development that benefit our discipline. Our members are involved in a number of such projects.

Software tool development

	nlmixr is a free and open source R package for fitting general dynamic models, pharmacokinetic (PK) models and pharmacokinetic-pharmacodynamic (PKPD) models in particular, using either individual data or population data. Rik and Justin are helping with its development and testing.
	Census is a free and open source project manager for NONMEM, providing detailed summary, comparison and overview of the runs comprising a given project, including the display of output data, simple post-run processing, diagnostic plots and run output management, complementary to other available modelling aids. Justin is its lead developer.

Volunteer activities

	The International Society of Pharmacometrics (ISoP) has as its mission the promotion and advancement of the discipline of pharmacometrics, through integration, innovation, and impact. Currently engaged in a concentrated attempt to expand its membership beyond its traditionally North American core, ISoP also organizes the annual American Conference on Pharmacometrics (ACoP). Justin was elected to the ISoP Board of Directors in 2015, has chaired its Standards and Practices Committee, and began his term as President of ISoP in October 2018.
	The Population Approach Group in Europe (PAGE) is a community with a shared interest in data analysis using the population approach. PAGE organizes an iconic conference in a different European city every year. Rik, Janet, Justin and Julia have been involved in organizing the meeting since 1996, 1999, 2013, and 2015, respectively.
	The DDMoRe Foundation will continue the work of the DDMoRe Consortium going forward. Justin coordinated the Thoughtflow Community Group.
