Nahal Rose Lalefar

Nahal Rose Lalefar, MD is an Associate Professor of Pediatrics at the University of California San Francisco (UCSF). She specializes in pediatric hematology/oncology with a focus on stem cell transplantation. She leads the bone marrow transplant long-term follow-up program at UCSF Benioff Children's Hospital Oakland and operates a hematology clinic at UCSF-Fresno.

• Education: BA (UC Berkeley, 2001), Biotech Certificate (CSU Hayward, 2003), MD (UC Davis, 2008), Pediatrics Residency (UCSF Fresno, 2001-2005), Pediatric Hematology/Oncology Fellowship (UCSF Benioff Children's Hospital Oakland, 2015)

Her research centers on optimizing stem cell transplantation outcomes through pharmacokinetic modeling, immune suppression strategies, and long-term complication management. Key collaborations include the Pediatric Transplantation and Cell Therapy Consortium and multicenter trials on GVHD prevention.

Recent publications analyze:

• Mechanisms of graft-versus-host disease (GVHD) in pediatric haploidentical transplants
• Pharmacokinetic optimization of melphalan and fludarabine
• Impact of pulmonary microbiome dysbiosis on transplant mortality
• Fertility preservation challenges in stem cell transplant survivors
• Racial disparities in unrelated donor transplant outcomes

Scientific awards include the ASBMT Travel Grant and multiple UC Davis/UCSF Fresno scholarships. She contributes to clinical trials on costimulation blockade and transplant-associated thrombotic microangiopathy.
