معرفی
Tomoko Komada is Professor of Chemistry at San Francisco State University, affiliated with the Estuary & Ocean Science Center in Tiburon, California. Her research is centered on marine biogeochemistry, particularly the cycling and preservation of organic carbon at land-ocean margins. She leads the Komada Lab, where isotopic and molecular approaches are used to study sedimentary processes.
Research Interests: Dr. Komada's work investigates the sources, transformation, and fate of organic matter in marine and estuarine environments. Key areas include:
- Sediment biogeochemistry and benthic carbon cycling
- Dissolved organic matter (DOM) production and export from marine sediments
- Organic carbon preservation in salt marshes, especially minerogenic systems in San Francisco Bay
- Use of natural abundance radiocarbon (¹⁴C) and stable carbon isotope (¹³C) tracers
- Role of organic-mineral associations in organic matter stability
- Molecular characterization of complex organic matter using NMR and other analytical techniques
Publication Trends: Her recent publications focus on the molecular composition and abiotic formation of organic matter in anoxic marine sediments, particularly in the Santa Barbara Basin. These studies combine field sampling, isotopic analysis, and advanced spectroscopy to uncover reaction pathways and preservation mechanisms of organic carbon and sulfur compounds. There is a strong emphasis on early diagenetic processes and the role of sediments in the global carbon cycle.
