My expertise is in both oncology and hematology. Although a large percentage of my time is spent in the laboratory, I enjoy taking care of patients at Children’s Hospital. My research has given me a broad clinical approach that helps me diagnosis and treat the rare child who is “off the grid,” particularly when there is an oncology/hematology problem that has gone unsolved. I focus on treating patients with acute lymphoblastic leukemia (ALL) and with autoimmune diseases. I also specialize in hematopoietic stem cell transplant (bone marrow transplant) and use my expertise in transplant to help treat patients with leukemia and autoimmune disease.
My research is primarily focused on developing new therapies for children with white blood cell diseases, including ALL and a rare autoimmune disease called Autoimmune Lymphoproliferative Syndrome (ALPS). My research in ALL focuses on studying leukemic cells from children with high-risk disease. I take a “bench-to-bedside” approach and test new therapies in my lab and then try to bring those therapies to the clinic. This work, performed in collaboration with the Children’s Oncology Group (COG), has allowed me to study patient samples from hundreds of children with rare forms of childhood leukemia. My investigation of new “targeted” therapies has led to a number of local and national clinical trials. On many of these trials, I have served in a leadership role either as a Vice Chair or Study Chair, and for many of these trials the correlative biology is performed in my lab. I am currently the Vice Chair for Biology for the ALL Disease Committee in COG. I am also the national study chair for one of the largest pediatric T cell ALL (T-ALL) trials ever performed. This trial opened in 2014 and is expected to treat over 1200 patients at over 200 participating institutions in North America, Europe, and Australia. My experience in translational research of T-ALL and past experience in early phase trials qualified me to take this position.
An additional major area of research centers on investigating novel therapeutics and in autoimmune and lymphoproliferative diseases, particularly ALPS. ALPS was thought to be a rare disease, but early in my career I demonstrated it is more common than previously thought as many patients were misdiagnosed. Using preclinical models, I have studied ALPS in the lab and found that ALPS cells are very sensitive to a drug calle sirolimus. Based on this work, I opened a study treating patients with ALPS with sirolimus. Prior to using sirolimus for ALPS, there was no effective treatment that could improve the lymphoproliferative and autoimmune manifestations of the disease. I have treated over 50 patients with ALPS from all over the globe with sirolimus. Over 90% of these patients have had a complete and durable response to this single agent therapy. Indeed, sirolimus has revolutionized the treatment of ALPS and has become the standard of care for this disease.
My final area of research expertise is dedicated to understanding hemophagocytic lymphohistiocytosis (HLH), with emphasis on understanding why patients treated with T-cell engaging therapies, including chimeric antigen receptor (CAR) T cells and bi-specific T-cell engaging antibodies (BITE) who develop severe cytokine release syndrome develop secondary HLH. I made the initial observation that patients treated with CAR T cells and blinatumomab develop a clinical, laboratory, and cytokine profile similar to HLH. It was this observation that helped lead to IL6-directed therapy with tocilizumab post-CAR T cells. Currently, patients treated with CAR T cells are followed for HLH and on-going research is dedicated to understanding secondary HLH after these therapies.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
