Laboratory for Molecular Pediatric Pathology (LaMPP) | Meet Our Team

Marian Harris, MD, PhD

Medical Director

Marian H. Harris, MD, PhD, is the director of the Boston Children’s Hospital Laboratory for Molecular Pediatric Pathology (LaMPP), as well as a practicing hematopathologist and molecular pathologist at Boston Children’s. She received her MD and PhD from the University of Pennsylvania, completed her residency in Anatomic Pathology and fellowship in Hematopathology at Brigham and Women’s Hospital, and completed her fellowship in Molecular Genetic Pathology at Harvard Medical School. Harris’s clinical and translational research focuses on molecular diagnostics in the context of pediatric malignancy and hematologic disease. She is particularly interested in using molecular diagnostics to refine pathologic diagnoses, as well as to provide prognostic and therapeutic guidance in clinical care, and is a co-investigator on a number of multi-institutional clinical trials using molecular diagnostics for these purposes.

Alanna Church, MD

Associate Medical Director

Alanna Church, MD, is the associate director of LaMPP. She received her MD from Queen’s University in Canada, where she also completed her residency in Anatomic Pathology. She completed her fellowship in Molecular Genetic Pathology at Harvard Medical School and her Pediatric Pathology fellowship at Boston Children’s. Her clinical focus is on the integration of molecular diagnostics into the care of children with extracranial solid tumors, including sarcomas, liver tumors and vascular anomalies. She directs the LaMPP Informatics Division. She is the lead pathologist for the iCat2/GAIN consortium study to detect actionable genetic alterations in tumors of children with high risk solid tumors. Dr. Church is actively engaged in the education of trainees and is an associate program director for the Harvard Medical School Molecular Genetic Pathology Fellowship training program.
