Dr. Martinez-Outschoorn’s research centers on how cancer cells interact metabolically with surrounding stromal cells, particularly in head and neck squamous cell carcinoma (HNSCC). He has shown that cigarette smoke alters cell metabolism in HNSCC, creating a tumor environment that supports cancer growth. He leads a lab focused on studying these metabolic profiles and has secured dedicated research funding. In breast cancer, his NIH-funded work explores how metabolic coupling between epithelial and stromal cells drives antiestrogen resistance, including investigations into the potential of N-acetylcysteine to reverse this effect.
