Scientific Interests

Dr. Steven Mittelman is interested in understanding how obesity worsens cancer outcomes, specifically in children with acute lymphoblastic leukemia (ALL). He investigates the relationships between adipocytes and ALL cells, evaluating effects on chemotherapy pharmacokinetics, cancer metabolism and treatment resistance. His research primarily involves cell culture, pre-clinical models and human samples.
