Stephen S Hecht

Stephen S Hecht is a Professor in the Department of Laboratory Medicine and Pathology at the University of Minnesota Medical School, specializing in carcinogenesis and chemoprevention research. His work focuses on tobacco carcinogens, particularly tobacco-specific nitrosamines like NNK (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone).

His research interests center on tobacco carcinogenesis, with expertise in DNA adduct formation, biomarker development for cancer risk assessment, and ethnic disparities in tobacco-related cancers. Key areas include metabolic activation of carcinogens, quantitative analysis of tobacco toxins, and molecular mechanisms of cancer progression.

Analysis of recent publications (2024-2025) reveals strong focus on tobacco-specific nitrosamines and their role in DNA damage, with expanding work on e-cigarette constituents and pancreatic cancer mechanisms. His studies integrate mass spectrometry, molecular epidemiology, and in vitro models to address cancer prevention.

• NIH-funded projects on ethnic/racial differences in lung cancer (2022-2027)
• Head/neck cancer biomarker study via DNA adduct analysis (2021-2026)
• Minnesota HHEAR Targeted Analysis Laboratory (2019-2025)
• Population Assessment of Tobacco and Health (PATH) Study (2016-2026)

He leads multi-institutional collaborations with researchers at the National Cancer Institute, Westat Inc., and environmental health institutes. His laboratory develops advanced mass spectrometry methods for carcinogen-DNA adduct detection and participates in large cohort studies like the Southern Community Cohort Study.
