Dr. Maria Monica Gramatges is the Research Co-Director of the Long-Term Survivor Program at Texas Children’s Cancer and Hematology Centers. In that role, she develops and facilitates local and national collaborative research that investigates the physical, medical, and psychosocial late effects of treatment for childhood cancer.

Dr. Gramatges serves as Chair of the Texas Children’s Cancer and Hematology Centers Practice Standards Committee. The objective of this committee is to develop and establish standards of practice that are based on the available evidence for the non-research related treatment of hematological/oncological diseases, as well as for related supportive care efforts.

Research Statement

The objectives of the Gramatges lab are to uncover genetic risks, such as underlying defects in telomere maintenance, that may predispose children to cancer and cancer therapy-related toxicities as well as late effects. Her research explores these associations using human samples obtained locally and in collaboration with organizations such as the Children’s Oncology Group and the Childhood Cancer Survivor Study. Of particular interest to her lab are biomarkers of aging and frailty, and how these biological factors are related to features of premature, accelerated aging observed in survivors of childhood cancer.
