I am an Assistant Professor for Pediatric Hematology and an Attending physician with the Division of Hemostasis and Thrombosis at Northwell Health. I completed my graduate medical training in Pediatric Hematology/Oncology in June 2021. My primary research interest started during my Fellowship. Understandably, as a physician in training, I engaged in answering different research questions to broaden my learning and understanding.

My current research projects include basic science and clinical research projects in Pediatric Hematology. I have several completed and ongoing clinical research projects in hemostasis and thrombosis. I am analyzing real world data for the use of emicizumab in patients with Hemophilia. The preliminary findings were presented at the annual American Society of Hematology meeting, 2020 and a manuscript is being draft currently. ( Some of my other works in the field of thrombosis and hemostasis which have been published include:

  1. Al-Ghafry, M., Vagrecha, A., et al. Multisystem inflammatory syndrome in children (MIS-C) and the prothrombotic state: Coagulation profiles and rotational thromboelastometry in a MIS-C cohort. J. Thromb. Haemost., 19: 1764-1770.
  2. Vagrecha A, Stanco J, Majeed S, Kouides P, Acharya SS. Primary thromboprophylaxis in a patient with type 3 von Willebrand disease and severe COVID-19 infection. Haemophilia. 2021;27(4):e517- e519.

I studied the role of a novel transcription factor Irf5 in mammalian erythropoiesis. The preliminary findings from studying erythropoiesis and erythroblastic islands in wild type and Irf5-/- global knockout C57Bl6 mice suggests a crucial role of Irf5 in erythropoiesis at both steady and stress states. This role is mediated through the polarization of macrophages which are central to the anatomic and functioning subunits of erythropoiesis – the erythroblastic islands. Preliminary findings for this project have been presented at the annual meeting of the American Society of Hematology as an oral abstract and was awarded the abstract achievement award. (

I am also involved in clinical research in pediatric HLH. Particularly, the use of anakinra, the outcomes and the role of genetic variants in the pathogenesis of related disorders. Some of these works have been published as listed below:

  1. Vagrecha A, Zhang M, Acharya S, Lozinsky S, Singer A, Levine C, Al-Ghafry M, Fein Levy C, Cron RQ. Hemophagocytic Lymphohistiocytosis Gene Variants in Multisystem Inflammatory Syndrome in Children. Biology. 2022; 11(3):417.
  2. Vagrecha A, Patel HB, Mamdouhi T, et al. Effect of COVID-19 on anakinra-induced remission in homozygous STX11 hemophagocytosis lymphohistiocytosis. Pediatr Blood Cancer. 2021;68(6):e28897.
  3. Bami S*, Vagrecha A*, et al. The use of anakinra in the treatment of secondary hemophagocytic lymphohistiocytosis. Pediatric Blood Cancer. 2020 Nov;67(11):e28581. (*co first authors)

Lastly, I also serve as the Associate P As a junior faculty in Hematology, I continue to further my academic interests in hematology, hemostasis and thrombosis.
