Professor of Clinical Medicine

Dr. Bernard M. Kubak is involved with the management of infections in solid-organ transplants and immunocompromised patients. Dr. Kubak is trained in Infectious Diseases and Microbiology. He received his Ph.D. training at Loyola University School of Medicine and performed post-doctoral research in immunology at Rush-Presbyterian St. Luke’s Medical Center; he received his medical education at Rush Medical College and post-graduate medical training at the University of California Los Angeles. Since 1993, he has been the formal representative to the UCLA heart and lung transplant program and the cardiac assist-device program. He directs the activities and training of staff in transplant infectious diseases.

He serves on the executive committees for transplant infectious diseases at the American Society of Transplantation (AST) & the International Society for Heart & Lung Transplantation (ISHLT). With the AST, he authored the guidelines on the prophylaxis & treatment of fungal infections and he continues to work with the society’s Community of Practice for infectious diseases topics in donor and recipient infections. Further, he participates in graduate medical educational activities with the AST, the ISHLT, & the American College of Physicians on the identification of high-risk patients for infections in solid organ transplants & ventricular assist devices, antimicrobial agents, and emerging pathogens. He completed chapters for the state-of-the-art review of clinical & investigative aspects of lung transplantation (2006) and is a continuing medical educator with other medical centers around the country on the management of infections in immmunocompromised patients.

He is listed in the Guide to Top Physicians in California (Infectious Diseases) for several years. He is a reviewer for several journals, has been principal investigator on trials in sepsis treatments, antifungal prophylaxis, and antiviral agents, and, also, is working with Drs. O. Yang and A. Gregson in transplant related research. He serves on the selection committees for heart and lung transplant, the epidemiology committee, and the bioterrorism task force, and he is the director for the David Geffen School of Medicine Infectious Disease elective.

Dr. Kubak's clinical research activities are listed below:

  • Community of Practice guidelines (AST): antifungal treatment and prophylaxis in solid-organ transplants
  • Extended donor use in heart and lung transplantation.
  • Infections in lung and heart transplant recipients, ventricular assist devices and artificial hearts.
  • Infections associated with extended-spectrum beta-lactamase producing bacteria, hepatitis C virus, endobronchial stents, Aspergillus & Coccidioides), & Influenza & respiratory viral infections in solid organ transplants.
