The focus of Dr. Dhall’s clinical research is to design and conduct clinical trials utilizing treatment strategies that either avoid or at least minimize the dose and volumes of irradiation in infants and young children with malignant brain tumors. His clinical trials also innovatively focus on children and young adults with CNS germ cell tumors

He has successfully chaired many local and multi-institutional clinical trials and has been involved in many leadership roles on various national committees, including the chairmanship of the Young Investigator’s Committee in Children’s Oncology Group (COG). He also serves as the Vice-Chair of the Institutional Review Board at CHLA and has mentored many students, residents, fellows, and junior faculty over the last 10 years who have now taken leadership roles at many prestigious institutions across the country.  

Clinical Interests

Caring for children and young adults with primary brain and spinal cord tumors.

Research Interests: 

Girish Dhall, MD, is dedicated to improving the survival rate of young children with brain tumors without using radiation therapy or minimizing the dose and volume of radiation therapy, which can cause severe and irreversible damage to intellectual functioning.  He is investigating innovative approaches for children who fail to respond to standard therapy; a mix of chemotherapy, radiation therapy, biologic therapy, and autologous hematopoietic stem cell transplantation. 

Dhall’s clinical research goal is to discover novel, research-based diagnostic and treatment options for brain and spinal cord tumors, which can be offered to patients of the Neuro-Oncology Program at Children’s Hospital Los Angeles. He serves as CHLA’s institutional principal investigator for a number of important clinical trial research consortia including:

  • Pediatric Brain Tumor Consortium - the study of correlative tumor biology and new therapies for primary CNS tumors of childhood with the objective to rapidly conduct novel phase I and phase II clinical evaluations of new therapeutic drugs, new biological therapies, treatment delivery technologies and radiation treatment strategies in children from infancy to 21 years of age with primary central nervous system tumors.
  • Neurofibromatosis (NF) Clinical Trials Consortium –clinical trials of novel medications in the treatment and prevention of neurofibromatosis.
  • Collaborative Ependymoma Research Network (CERN) – adult and pediatric neuro-oncologists working to find new treatments for ependymoma, a malignant brain tumor often found in young infants and children
  • Pacific Pediatric Neuro-Oncology Consortium (PNOC) – innovative clinical trials based on cutting-edge research in children and young adults with malignant brain tumors.
