Michele P. Lambert, MD, MSTR, is the Medical Director of the Special Coagulation Laboratory and an attending physician in the Division of Hematology at Children's Hospital of Philadelphia.

Areas of Expertise: Congenital platelet disorders, General hematology
Locations: Main Hospital

Appointments and Referrals: 1-800-TRY-CHOP (1-800-879-2467)


Michele Lambert, MD, received her undergraduate degree in Biology from Rensselaer Polytechnic Institute and attended medical school at Rutgers New Jersey Medical School. She did her residency in Pediatrics at St. Christopher’s Hospital for Children followed by a year as Chief Resident and then a Hematology/Oncology Fellowship at The Children’s Hospital of Philadelphia. She is now an Associate Professor of Pediatrics in The Perelman School of Medicine at the UPENN and a Pediatric Hematologist at the Children’s Hospital of Philadelphia where she is the clinical director of the special coagulation laboratory and co-director of the Frontier Program in Immune Dysregulation as well as the director of the Pediatric Platelet Disorder Program at CHOP. Her particular clinical interest is in the inherited and acquired platelet disorders and in the interplay between genetics and disease.

Her current research focuses on understanding the role of genetics in this space. She is a member of the ClinGen Hemostasis and Thrombosis clinical domain working group and a Co-Chair of the ClinGen Hemostasis and Thrombosis Hemostasis and Thrombosis Gene Curation Expert Panel as well as the current Chair of the pediatric ITP Consortium of North America. By understanding the drivers of differences in biology in platelet disorders, Dr. Lambert hopes to develop targeted therapies to improve outcomes.
