The TIAFT Communications Committee was created in 2013 (renamed from Social Media Committee in 2018) to support the aims of the TIAFT organization by promoting cooperation, discussion and the exchange of ideas among TIAFT members.

Aims of the Committee

The primary objective of the Communications Committee is to disseminate timely and accurate information about the organization’s policies, programs, services and events (such as the Annual Meetings). This is done via the website and social media pages (Twitter, LinkedIn, Facebook, Instagram).

The secondary objective is to serve the TIAFT community by providing platforms to members for sharing toxicology-related information. Amongst others, this is done via:

  • The Facebook discussion group, where members can ask questions or disseminate relevant information;
  • The Careers Centre, where toxicologists can look for job offers in their area of expertise posted by employers worldwide.
