Resources for Hematology Fellows

Meet the Trainee Council

Since 2001, the Trainee Council has provided a forum for hematology fellows to discuss issues relevant to fellowship training and career development and provides suggestions regarding programs that may increase interest in hematology. The council projects include Hematopoiesis, Ash-a-Palooza and other trainee activities at the ASH annual meeting, Grants Clearinghouse, ASH Hematology Career Planner, and more.

The Trainee Council consists of MD, MD, PhD, and PhD trainees from across North America. The council is governed by a chair who is elected by the members of the council and each council member serves a two-year term.

Since 2023 the council has expanded to include four new positions:

  • Medical student
  • PhD student in a hematology laboratory
  • Resident (MD, DO, MD/PhD enrolled in a duly accredited residency program related to internal medicine that may lead to hematology-related practice)
  • A clinical or post-doctoral fellow from outside of North America

Fellows are invited to apply for a position on the Trainee Council at the top of each year. Trainees who exhibit leadership qualities and a high potential for a successful career in hematology or a hematology-related discipline are the best fit.
