As a physician scientist in the hematological malignancies and stem cell transplantation division with Sidney Kimmel Comprehensive Cancer Center at the Johns Hopkins, my focus is on the various aspects of cellular therapy in the treatment of hematological malignancies. My primary research focus is to develop strategies to prevent relapse of hematological malignancies following allogeneic stem cell transplantation. Additionally, I serve as the director of the adult CAR T program for hematological malignancies as we grow our CAR T program to help patients with advanced hematological malignancies. My academic interest in this space lies in studying the aspects of toxicity of CAR T cell therapy with an aim to improve long term outcomes in these patients. Among hematological malignancies, myeloproliferative disorders are my area of interest and I work to study newer drugs in early phase of development and also its treatment using allogeneic stem cell transplantation.

Dr. Nara Lygia De Macena Sobreira is an assistant professor at the McKusick-Nathans Department of Genetic Medicine at Johns Hopkins University School of Medicine. Her area of expertise is rare Mendelian phenotypes, analysis of next-generation sequencing, and functional testing of candidate causative variants. She earned her M.D. at the University of Pernambuco in Brazil. She finished her Ph.D. in Human Genetics at Johns Hopkins followed by a one-year postdoc also at Johns Hopkins School of Medicine. During her Ph.D., she worked with Dr. David Valle using next-generation sequencing to elucidate the molecular basis of rare Mendelian phenotypes and in 2010 she discovered PTPN11 as the gene responsible for metachondromatosis by using whole-genome sequencing. She completed residencies in clinical genetics at both Universidade Federal de Sao Paulo and Johns Hopkins. Her main clinical and research focus is on identifying the genetic bases of rare phenotypes, mainly, phenotypes associated with cartilage tumors and vascular anomalies (including Ollier disease and Maffucci syndrome), and on understanding the physiopathology of these phenotypes to identify pharmacological strategies to treat them. She has worked extensively on developing strategies to better analyze the variants identified by next-generation sequencing and on novel strategies for data sharing. She participated on the development of PhenoDB, a phenotypic and genomic database, and created PhenoDB Variant Analysis Tool used worldwide. She is also one of the creators of GeneMatcher, VariantMatcher, and one of the co-founders of the Matchmaker Exchange, all intended to share next-generation sequencing data. She has also worked extensively on functional studies that evaluate the possible pathogenic effects of the candidate causative variants.
