Research Interests
-
Geology and geochemistry of fluid expulsion sites (cold seeps) along continental margins.
-
Sedimentology and diagenesis of marine sediments.
-
Fluid and sediment geochemistry with emphasis on gas hydrate bearing sedimentary sequences.
My research involves the study of fluid expulsion sites in several areas along the world's continental margins:
