Dr. Ramsingh's laboratory research interests include genetic changes underlying the development of leukemia in patients previously treated with chemotherapy. He is particularly focused on understanding the mechanism of aging in Hematopoietic stem and progenitor cells and its contribution to leukemogensis.

Dr. Ramsingh earned his medical degree from Christian Medical College, and then stayed on to perform his internship and residency. He then completed two fellowships, one in hematology/oncology, and the other in stem cell biology at Washington University School of Medicine.
