My studies are focused on the Late Cretaceous sea-level reconstructions. I integrate sequence stratigraphy, paleobathymetry and biostratigraphy to derive a record of Late Cretaceous sea-level changes on the New Jersey coastal plain. I conduct nannofossils biostratigraphy for age control. I use benthic foraminiferal assemblages for paleobathymetry estimates and apply integrated sequence stratigraphic analysis on the basis of physical stratigraphy, lithofacies analysis and geochronology. My studies provide high-resolution (<1myr) integrated stratigraphic record on New Jersey coastal plain that indicates large and rapid eustatic sea-level variations occurred in the Late Cretaceous In my future work, I will establish global correlation of Upper Cretaceous (Cenomanian-Campanian) depositional sequences between New Jersey coastal plain Russian Platform and Colorado Plateau regions. High resolution biostratigraphy of calcareous nannoplankton, and planktonic foraminifera will be applied for interregional correlation. The results will contribute to global estimates of sea-level changes and to interregional biostratigraphic and sequence stratigraphic reconstructions of Cenomanian-Campanian strata. Glacioeustasy
