Clinical and Research Requirements

The Transplant and Oncology Center within the Division of Infectious Diseases was established in 2008, with the overall goals to provide clinical care, clinical training, and academic scholarship directed to infectious complications unique to transplant and oncology patients.  A formal curriculum of training at multiple levels has been developed, including a GME- approved specialized fellowship program.  For more information, contact Darin Ostrander at (410) 614-6702,

Teaching is a top priority for the Hopkins TOID Faculty, who utilize (and have co-authored) the current AST- and IDSA-approved curriculum for Transplant ID training.

Trainees are exposed to an extraordinary variety of infectious and immunologic issues on a busy inpatient Transplant ID consultation service, with opportunity to participate in outpatient pre-transplant evaluation and continuity clinics. There are ample opportunities to do translational and clinical research for motivated fellows who would like to stay in program for a longer duration (up to two years).

Goals and Objectives for Fellowship Training

  • Identify major causes of opportunistic and other infections and the major clinical syndromes that occur in immunocompromised hosts, including patients with hematologic malignancies, following cancer therapy, and following hematopoietic stem cell and solid organ transplantation
  • Understand the ways in which immune defects alter the clinical presentations of infection
  • Understand principal diagnostic modalities including radiology, microbiology (including molecular and immunologic diagnostic assays), and histopathology, and the most effective application and limitations of each in this patient population
  • Understand the principles of treatment of infections in these patients, including selection of antimicrobial agents and adjunctive therapies, role of removal of foreign bodies/devices, role of surgery, role of prophylactic, preventative and preemptive treatment strategies, and the limitations of therapy
  • Become facile in the evaluation, differential diagnosis and treatment of acutely ill solid organ and stem cell transplant patients
  • Understand the major immunosuppressive medications (mechanism of action, adverse effects, etc.) and the management of drug interactions in these hosts

Electives Outside of the Fellowship

Visiting clinicians, clinical fellows, medical students, and undergraduates are accepted for electives in the subspecialty, from both United States and international hospitals.
