Pediatric Hematology Oncology

Areas of Interest

Clinical interest: oncology and chelation therapy, clinical trials. Research interest: Proteomics in cancer (Wilms tumor, osteosarcoma, neuroblastoma), sickle cell disease, childhood obesity and inflammatory bowel syndrome as well as glaucoma; Biobank collection and storage of serum, plasma, urine, aqueous and vitreous fluid.


The focus of Dr Ragg's clinical research involves the study of serum proteins in many childhood disease including cancer, sickle cell disease, obesity and inflammatory bowel disease. Dr. Ragg has designed many studies to collect the serum of children with different diseases; she implemented the computational infrastructure required for large biobanking efforts as well as the analytical procedures required to compare the serum proteins in different diseases.

Research & Grants

For many pediatric diseases, such as sickle cell disease and cancer, research has concentrated on studying individual biomarkers separately.   We hypothesized that combining the information of many proteins as well as several diseases would give us a more comprehensive picture on the changes of the serum proteome as it relates to different disease.  We use an integrated approach that measures several hundred proteins by protein antibody array as well as by Liquid chromatography-tandem mass spectrometry. In collaboration with the Children Oncology Group we have analyzed the proteomic signature of children with osteosarcoma, Wilms tumor and neuroblastoma and are currently comparing the signature of children with cancer to other disease such as sickle cell disease, obesity and inflammatory bowel syndrome.
