Postdoctoral Members

Postdoctoral membership in SOT provides early career toxicologists with opportunities for scientific growth, networking, and career advancement. All members of SOT who self-identify as postdoctoral scholars are part of the Postdoctoral Assembly (PDA), which was formed to increase involvement of postdocs in SOT and to address issues related to the postdoctoral experience. The PDA is governed by an elected PDA Executive Board who provide leadership for communications, strategic activities, and events of special interest to postdocs. Postdoctoral members serve leadership roles in the Society by participating as representatives for SOT Regional Chapters, Special Interest Groups, Specialty Sections, and to Committees.

How SOT Defines a Postdoc

The Society of Toxicology aligns its definition of a postdoctoral researcher closely with the definition set by the National Postdoctoral Association.

Characteristics that define a postdoctoral position include:

  • The postdoctoral appointment is temporary.
  • Effort is focused primarily on research.
  • The development of professional skills prepares the postdoc to actively pursue a career.
  • The postdoc is supervised by at least one senior scholar.
  • The postdoc is allowed and encouraged to publish the results of his or her research or scholarship.
  • The appointment is not part of a clinical training program.
Postdoctoral Assembly Leadership

All SOT Postdoctoral members are part of the Society’s Postdoctoral Assembly (PDA), which is governed by the elected PDA Executive Board. Postdoctoral representatives are appointed to SOT Regional Chapters, Special Interest Groups, Specialty Sections, and some SOT Committees to enhance the involvement of postdoctoral scholars within SOT.
