Peled Laboratory
Meet the Team
Principal
Investigator
Jonathan (Tsoni) Peled, MD PhD
After undergraduate studies at the University of Illinois, MD/PhD studies at Albert Einstein College of Medicine, and medical residency at Massachusetts General Hospital in Boston, Jonathan Peled did a heme/onc fellowship at Memorial Sloan Kettering Cancer Center and in 2016 joined the Adult Bone Marrow Transplantation Service in the Department of Medicine of MSKCC, where he serves as an Assistant Attending. He launched an independent laboratory in 2022 where he and his research team focus on the mechanisms by which commensal bacteria modulate host immunity, specifically within the context of cancer immunotherapy, including allogeneic hematopoietic cell transplantation. His laboratory is part of Memorial Hospital Laboratories and he holds a secondary appointment in the Human Oncology Pathogenesis Program (HOPP). He also serves as the Associate Director of the MSKCC Center for Hematological Malignancies.
Madhumitha Rangesa
Madhu received her Master’s degree in Biotechnology from New York University. Prior to joining the Peled Lab, her research centered on the development of dendritic cell vaccines with targeted mRNA tumor antigens in multiple myeloma. Since joining the Peled lab in 2022 she has been studying Enterococcus domination of the microbiome in cancer, investigating their role in graft-versus-host-disease using mouse models.

Graduate Research
Assistant
LeeAnn is a medical student at the State University of New York Downstate College of Medicine. She graduated from Cornell University in 2019 with a Bachelor's Degree in Human Biology, Health, and Society. During her three gap years before medical school, LeeAnn worked in clinical research at MSK in the Adult Bone Marrow Transplant service and in the van den Brink Lab. LeeAnn has interests in data science, the gut microbiome, and stem cell transplantation. In the Peled Lab, LeeAnn is investigating the role of the gut microbiome in the development of Graft-vs-Host Disease (GVHD).
